YouTube is an American online video sharing platform owned by Google. YouTube was founded on February 14, 2005,[7] by Chad Hurley, Jawed Karim, and Steve Chen, who were former employees of PayPal. Headquartered in San Bruno, California, it is the second-most-visited website in the world, after Google. In January 2024, YouTube had more than 2.7 billion monthly active users, who collectively watched more than one billion hours of videos every day.[8] As of May 2019, videos were being uploaded to the platform at a rate of more than 500 hours of content per minute,[9][10] and as of mid-2024, there were approximately 14.8 billion videos in total.[11]

Key Information

On November 13, 2006, YouTube was purchased by Google for US$1.65 billion (equivalent to $2.39 billion in 2024).[12] Google expanded YouTube's business model from generating revenue through advertisements alone to offering paid content such as movies and exclusive content explicitly produced for YouTube. It also offers YouTube Premium, a paid subscription option for watching content without ads. YouTube incorporated the Google AdSense program, generating more revenue for both YouTube and approved content creators. In 2023, YouTube's advertising revenue totaled $31.7 billion, a 2% increase from the $31.1 billion reported in 2022.[13] From Q4 2023 to Q3 2024, YouTube's combined revenue from advertising and subscriptions exceeded $50 billion.[14]

Since its purchase by Google, YouTube has expanded beyond the core website into mobile apps, network television, and the ability to link with other platforms. Video categories on YouTube include music videos, video clips, news, short and feature films, songs, documentaries, movie trailers, teasers, TV spots, live streams, vlogs, and more. Most content is generated by individuals, including collaborations between YouTubers and corporate sponsors. Established media, news, and entertainment corporations have also created and expanded their visibility to YouTube channels to reach bigger audiences.

YouTube has had unprecedented social impact, influencing popular culture, internet trends, and creating multimillionaire celebrities. Despite its growth and success, the platform has been criticized for its facilitation of the spread of misinformation and copyrighted content, routinely violating its users' privacy, excessive censorship, endangering the safety of children and their well-being, and for its inconsistent implementation of platform guidelines.

History

[edit]

Founding and initial growth (2005–2006)

[edit]
The founders of YouTube

YouTube was founded by Chad Hurley, Jawed Karim, and Steve Chen. The three were early employees at PayPal and had become wealthy after eBay's acquisition of the company.[15] Hurley had studied design at the Indiana University of Pennsylvania, and Chen and Karim studied computer science together at the University of Illinois Urbana-Champaign.[16]

According to a story that has often been repeated in the media, Hurley and Chen developed the idea for YouTube during the early months of 2005, after they had experienced difficulty sharing videos that had been shot at a dinner party at Chen's apartment in San Francisco. Karim did not attend the party and denied that it had occurred, but Chen remarked that the idea that YouTube was founded after a dinner party "was probably very strengthened by marketing ideas around creating a story that was very digestible".[17]

Karim said the inspiration for YouTube came from the Super Bowl XXXVIII halftime show controversy when Janet Jackson's breast was briefly exposed by Justin Timberlake during the halftime show. Karim could not easily find video clips of the incident and the 2004 Indian Ocean tsunami online, which led to the idea of a video-sharing site.[18][19] Hurley and Chen said that the original idea for YouTube was a video version of an online dating service and had been influenced by the website Hot or Not.[17][20] They created posts on Craigslist asking attractive women to upload videos of themselves to YouTube in exchange for a $100 reward.[21] Difficulty in finding enough dating videos led to a change of plans, with the site's founders deciding to accept uploads of any video.[22]

The YouTube logo used from its launch until 2007. It returned in 2008 before being removed again in 2010. Another version without "Broadcast Yourself" was used until 2011.

YouTube began as a venture capital–funded technology startup. Between November 2005 and April 2006, the company raised money from various investors, with Sequoia Capital and Artis Capital Management being the largest two.[15][23] YouTube's early headquarters were situated above a pizzeria and a Japanese restaurant in San Mateo, California.[24] In February 2005, the company registered www.youtube.com.[25] The first video was uploaded on April 23, 2005. Titled "Me at the zoo", it shows co-founder Jawed Karim at the San Diego Zoo and can still be viewed on the site.[26][27] The same day, the company launched a public beta and by November, a Nike ad featuring Ronaldinho became the first video to reach one million total views.[28][29] The site exited beta in December 2005, by which time the site was receiving 8 million views a day.[30][31] Clips at the time were limited to 100 megabytes, as little as 30 seconds of footage.[32]

YouTube was not the first video-sharing site on the Internet; Vimeo was founded in November 2004, though that site remained a side project of its developers from CollegeHumor.[33] On December 17, 2005—the same week YouTube exited beta—NBCUniversal Saturday Night Live ran a sketch "Lazy Sunday" by The Lonely Island. Besides helping to bolster ratings and long-term viewership for Saturday Night Live, "Lazy Sunday"'s status as an early viral video helped establish YouTube as an important website.[34] Unofficial uploads of the skit to YouTube drew in more than five million collective views by February 2006 before they were removed when NBCUniversal requested it two months later based on copyright concerns.[35] Despite eventually being taken down, these duplicate uploads of the skit helped popularize YouTube's reach and led to the upload of more third-party content.[36][37] The site grew rapidly; in July 2006, the company announced that more than 65,000 new videos were being uploaded every day and that the site was receiving 100 million video views per day.[38]

The choice of the name youtube.com led to problems for a similarly named website, utube.com. That site's owner, Universal Tube & Rollform Equipment (Universal Tube), filed a lawsuit against YouTube in November 2006, after being regularly overloaded by people looking for YouTube. Universal Tube subsequently changed its website to www.utubeonline.com.[39][40][41]

"Broadcast Yourself" era (2006–2013)

[edit]

On October 9, 2006, Google announced that they had acquired YouTube for $1.65 billion in Google stock.[42][43] The deal was finalized on November 13, 2006.[44][45] Google's acquisition launched newfound interest in video-sharing sites; IAC, which now owned Vimeo, focused on supporting the content creators to distinguish itself from YouTube.[33] It was at this time that YouTube adopted the slogan "Broadcast Yourself". The company experienced rapid growth. The Daily Telegraph wrote that in 2007, YouTube consumed as much bandwidth as the entire Internet in 2000.[46] By 2010, the company had reached a market share of around 43% and more than 14 billion views of videos, according to comScore.[47] That year, the company simplified its interface to increase the time users would spend on the site.[48]

In 2011, more than three billion videos were being watched each day with 48 hours of new videos uploaded every minute.[49][50][51] However, most of these views came from a relatively small number of videos; according to a software engineer at that time, 30% of videos accounted for 99% of views on the site.[52] That year, the company again changed its interface and at the same time, introduced a new logo with a darker shade of red.[53][54] A subsequent interface change, designed to unify the experience across desktop, TV, and mobile, was rolled out in 2013.[55] By that point, more than 100 hours were being uploaded every minute, increasing to 300 hours by November 2014.[56][57]

YouTube's headquarters in San Bruno, California, April 2017

During that time, the company also went through some organizational changes. In October 2006, YouTube moved to a new office in San Bruno, California.[58] Hurley announced that he would be stepping down as chief executive officer of YouTube to take an advisory role and that Salar Kamangar would take over as head of the company in October 2010.[59] In April 2009, YouTube partnered with Vevo.[60] In April 2010, Lady Gaga's "Bad Romance" became the most-viewed video, becoming the first video to reach 200 million views on May 9, 2010.[61]

YouTube faced a major lawsuit by Viacom International in 2011 that nearly resulted in the discontinuation of the website. The lawsuit was filed due to alleged copyright infringement of Viacom's material by YouTube. However, the United States Court of Appeals for the Second Circuit ruled that YouTube was not liable, and thus YouTube won the case in 2012.[62]

Susan Wojcicki's leadership (2014–2023)

[edit]

Susan Wojcicki was appointed CEO of YouTube in February 2014.[63] In January 2016, YouTube expanded its headquarters in San Bruno by purchasing an office park for $215 million. The complex has 51,468 square metres (554,000 square feet) of space and can house up to 2,800 employees.[64] YouTube officially launched the "polymer" redesign of its user interfaces based on Material Design language as its default, as well as a redesigned logo that is built around the service's play button emblem in August 2017.[65]

Through this period, YouTube tried several new ways to generate revenue beyond advertisements. In 2013, YouTube launched a pilot program for content providers to offer premium, subscription-based channels.[66][67] This effort was discontinued in January 2018 and relaunched in June, with US$4.99 channel subscriptions.[68][69] These channel subscriptions complemented the existing Super Chat ability, launched in 2017, which allows viewers to donate between $1 and $500 to have their comment highlighted.[70] In 2014, YouTube announced a subscription service known as "Music Key", which bundled ad-free streaming of music content on YouTube with the existing Google Play Music service.[71] The service continued to evolve in 2015 when YouTube announced YouTube Red, a new premium service that would offer ad-free access to all content on the platform (succeeding the Music Key service released the previous year), premium original series, and films produced by YouTube personalities, as well as background playback of content on mobile devices. YouTube also released YouTube Music, a third app oriented towards streaming and discovering the music content hosted on the YouTube platform.[72][73][74]

The company also attempted to create products appealing to specific viewers. YouTube released a mobile app known as YouTube Kids in 2015, which was designed to provide an experience optimized for children. It features a simplified user interface, curated selections of channels featuring age-appropriate content, and parental control features.[75] Also in 2015, YouTube launched YouTube Gaming—a video gaming-oriented vertical and app for videos and live streaming, intended to compete with the Amazon.com-owned Twitch.[76] In April 2018, a shooting occurred at YouTube's headquarters in San Bruno, California, which wounded four and resulted in the death of the shooter.[77]

By February 2017, one billion hours of YouTube videos were being watched every day, and 400 hours worth of videos were uploaded every minute.[8][78] Two years later, the uploads had risen to more than 500 hours per minute.[9] During the COVID-19 pandemic, when most of the world was under stay-at-home orders, usage of services like YouTube significantly increased. Forbes estimated that YouTube accounted for 16% of all internet traffic, as of 2024, up from 11% in 2018, before the pandemic.[79][80] In response to EU officials requesting that such services reduce bandwidth to make sure medical entities had sufficient bandwidth to share information, YouTube and Netflix said they would reduce streaming quality for at least thirty days as to cut bandwidth use of their services by 25% to comply with the EU's request.[81] YouTube later announced that they would continue with this move worldwide: "We continue to work closely with governments and network operators around the globe to do our part to minimize stress on the system during this unprecedented situation."[82]

After a 2018 complaint alleging violations of the Children's Online Privacy Protection Act (COPPA),[83] the company was fined $170 million by the FTC for collecting personal information from minors under the age of 13.[84] YouTube was also ordered to create systems to increase children's privacy.[85][86] Following criticisms of its implementation of those systems, YouTube started treating all videos designated as "made for kids" as liable under COPPA on January 6, 2020.[87][88] Joining the YouTube Kids app, the company created a supervised mode, designed more for tweens, in 2021.[89] Additionally, to compete with TikTok and Instagram Reels, YouTube released YouTube Shorts, a short-form video platform.[90] During that period, YouTube entered disputes with other tech companies. For over a year, in 2018–19, no YouTube app was available for Amazon Fire products.[91] In 2020, Roku removed the YouTube TV app from its streaming store after the two companies were unable to reach an agreement.[92]

After testing earlier in 2021, YouTube removed public display of dislike counts on videos in November 2021, claiming the reason for the removal was, based on its internal research, that users often used the dislike feature as a form of cyberbullying and brigading.[93] While some users praised the move as a way to discourage trolls, others felt that hiding dislikes would make it harder for viewers to recognize clickbait or unhelpful videos and that other features already existed for creators to limit bullying. YouTube co-founder Jawed Karim referred to the update as "a stupid idea", and said that the real reason behind the change was "not a good one, and not one that will be publicly disclosed." He felt that users' ability on a social platform to identify harmful content was essential, saying, "The process works, and there's a name for it: the wisdom of the crowds. The process breaks when the platform interferes with it. Then, the platform invariably declines."[94][95][96] Shortly after the announcement, software developer Dmitry Selivanov created Return YouTube Dislike, an open-source, third-party browser extension for Chrome and Firefox that allows users to see a video's number of dislikes.[97] In a letter published on January 25, 2022, by then YouTube CEO Susan Wojcicki, acknowledged that removing public dislike counts was a controversial decision, but reiterated that she stands by this decision, claiming that "it reduced dislike attacks."[98]

In 2022, YouTube launched an experiment where the company would show users who watched longer videos on TVs a long chain of short unskippable adverts, intending to consolidate all ads into the beginning of a video. Following public outrage over the unprecedented amount of unskippable ads, YouTube "ended" the experiment on September 19 of the same year.[99] In October, YouTube announced that they would be rolling out customizable user handles in addition to channel names, which would also become channel URLs.[100]

Neal Mohan leadership (2023–present)

[edit]
YouTube logo from August 2017 until February 2025

On February 16, 2023, Wojcicki announced that she would step down as CEO, with Neal Mohan named as her successor. Wojcicki took on an advisory role for Google and parent company Alphabet.[101] Wojcicki died a year and a half later from non-small-cell lung cancer, on August 9, 2024.[102] In late October 2023, YouTube began cracking down on the use of ad blockers on the platform. Users of ad blockers may be given a pop-up warning saying "Video player will be blocked after 3 videos". Users of ad blockers are shown a message asking them to allow ads or inviting them to subscribe to the ad-free YouTube Premium subscription plan. YouTube says that the use of ad blockers violates its terms of service.[103][104] In April 2024, YouTube announced it would be "strengthening our enforcement on third-party apps that violate YouTube's Terms of Service, specifically ad-blocking apps".[105] Starting in June 2024, Google Chrome announced that it would be replacing Manifest V2 in favor of Manifest V3, effectively killing support for most ad-blockers.[106] Around the same time, YouTube started using server-side ad injection, which allows the platform to inject the ads directly into the video, instead of having the ad as a separate file which can be blocked.[107]

In September 2023, YouTube announced an in-app gaming platform called Playables. It was made accessible to all users in May 2024, expanding from an initial offering limited to premium subscribers. In December 2024, YouTube began testing a new multiplayer feature for that service, supporting multiplayer functionality across desktop and mobile devices. As of December 2024 the Playables catalog has over 130 games in various genres, including trivia, action and sports.[108][109] In December 2024, YouTube introduced new guidelines prohibiting videos with clickbait titles to enhance content quality and combat misinformation. The platform aims to penalize creators using misleading or sensationalized titles, with potential actions including video removal or channel suspension.[110] According to YouTube, this guideline will gradually roll out in India first, but will expand to more countries in the coming months.[111]

On February 14, 2025, YouTube celebrated 20 years since its founding.[112] On July 30, 2025, amid the implementation of the Online Safety Act 2023 in the United Kingdom, Google announced that it would begin to enforce "age assurance" policies for selected users in the United States as a trial. Machine learning will be used to determine the age of the user (regardless of any account information indicating their age) and restrict access to certain content and features across all Google properties, including YouTube (including, in particular, disabling personalized advertising and enabling certain digital wellbeing limits), if they are assumed to be under 18. On YouTube, this will be based on factors such as searches and video history, and the age of the account. The user must go through age verification via payment, scanned ID, or selfie to access all features if they are detected to be a minor.[113][114] On April 9, 2025, YouTube expressed support for the NO FAKES Act of 2025, introduced by Senator Chris Coons (D-DE) and Senator Marsha Blackburn (R-TN), and announced an expansion of its pilot program that is designed to identify content generated by AI.[115]

On September 23, 2025, YouTube parent company Alphabet announced that it would reinstate creators that were banned for spreading misinformation about COVID-19 and the 2020 U.S. presidential election.[116] Within the context of the suspension of Jimmy Kimmel and debates about free speech in the United States, Vice President JD Vance defended Kimmel's suspension and instead cited a letter sent by Alphabet legal counsel Daniel F. Donovan to U.S. House Judiciary Committee chairman Jim Jordan, claiming the Biden administration pressured YouTube to remove "non-violative user-generated content" containing misinformation about the COVID-19 pandemic and the 2020 election, and announced that it would reinstate content creators previously banned due to the cited content;[117][118] however, such claims have not formally been proven, and the U.S. Supreme Court dismissed in 2024 the First Amendment case Murthy v. Missouri (which claimed the Biden administration had pressured social media companies to censor conservative views, government criticism, and COVID-19 misinformation), ruling 6–3 that neither the attorneys general of Missouri and Louisiana nor other respondents had standing to bring the case. The decision of Alphabet to bring back YouTube creators who engaged in misinformation was criticized for prioritizing "free expression" over "facts".[119]

Senior leadership

[edit]

YouTube has been led by a CEO since its founding in 2005, beginning with Chad Hurley, who led the company until 2010. After Google's acquisition of YouTube, the CEO role was retained. Salar Kamangar took over Hurley's position and kept the job until 2014. He was replaced by Susan Wojcicki, who later resigned in 2023.[101] On February 16, 2023, Neal Mohan was appointed as the new CEO.[101]

Features

[edit]

YouTube offers different features based on user verification, such as standard or basic features like uploading videos, creating playlists, and using YouTube Music, with limits based on daily activity (verification via phone number or channel history increases feature availability and daily usage limits); intermediate or additional features like longer videos (over 15 minutes), live streaming, custom thumbnails, and creating podcasts; advanced features like content ID appeals, embedding live streams, applying for monetization, clickable links, adding chapters, and pinning comments on videos or posts.[120]

Videos

[edit]

In January 2012, it was estimated that visitors to YouTube spent an average of 15 minutes a day on the site, in contrast to the four or five hours a day spent by a typical US citizen watching television.[121] In 2017, viewers on average watched YouTube on mobile devices for more than an hour every day.[122] In December 2012, two billion views were removed from the view counts of Universal and Sony music videos on YouTube, prompting a claim by The Daily Dot that the views had been deleted due to a violation of the site's terms of service, which ban the use of automated processes to inflate view counts. That was disputed by Billboard, which said that the two billion views had been moved to Vevo, since the videos were no longer active on YouTube.[123][124]

On August 5, 2015, YouTube patched the formerly notorious behavior which caused a video's view count to freeze at "301" (later "301+") until the actual count was verified to prevent view count fraud.[125] YouTube view counts again began updating in real time.[126] Since September 2019, subscriber counts are abbreviated. Only three leading digits of channels' subscriber counts are indicated publicly, compromising the function of third-party real-time indicators such as Social Blade. Exact counts remain available to channel operators inside YouTube Studio.[127]

On November 11, 2021, after testing out this change in March of the same year, YouTube announced it would start hiding dislike counts on videos, making them invisible to viewers. The company stated the decision was in response to experiments which confirmed that smaller YouTube creators were more likely to be targeted in dislike brigading and harassment. Creators will still be able to see the number of likes and dislikes in the YouTube Studio dashboard tool, according to YouTube.[128][129][130] YouTube has an estimated 14.8 billion videos with about 4% of those never having a view.[11] Just over 85% have fewer than 1,000 views.[131]

[edit]

YouTube has faced numerous challenges and criticisms in its attempts to deal with copyright, including the site's first viral video, Lazy Sunday, which had to be taken down, due to copyright concerns.[132] At the time of uploading a video, YouTube users are shown a message asking them not to violate copyright laws.[133] Despite this advice, many unauthorized clips of copyrighted material remain on YouTube. YouTube does not view videos before they are posted online, and it is left to copyright holders to issue a DMCA takedown notice pursuant to the terms of the Online Copyright Infringement Liability Limitation Act. Any successful complaint about copyright infringement results in a YouTube copyright strike. Three successful complaints for copyright infringement against a user account will result in the account and all of its uploaded videos being deleted.[134][135] From 2007 to 2009 organizations including Viacom, Mediaset, and the English Premier League have filed lawsuits against YouTube, claiming that it has done too little to prevent the uploading of copyrighted material.[136][137][138]

In August 2008, a US court ruled in Lenz v. Universal Music Corp. that copyright holders cannot order the removal of an online file without first determining whether the posting reflected fair use of the material.[139] YouTube's owner Google announced in November 2015 that they would help cover the legal cost in select cases where they believe fair use defenses apply.[140] In the 2011 case of Smith v. Summit Entertainment LLC, professional singer Matt Smith sued Summit Entertainment for the wrongful use of copyright takedown notices on YouTube.[141] He asserted seven causes of action, and four were ruled in Smith's favor.[142] In April 2012, a court in Hamburg ruled that YouTube could be held responsible for copyrighted material posted by its users.[143] On November 1, 2016, the dispute with GEMA was resolved, with Google content ID being used to allow advertisements to be added to videos with content protected by GEMA.[144]

In April 2013, it was reported that Universal Music Group and YouTube have a contractual agreement that prevents content blocked on YouTube by a request from UMG from being restored, even if the uploader of the video files a DMCA counter-notice.[145][146] As part of YouTube Music, Universal and YouTube signed an agreement in 2017, which was followed by separate agreements other major labels, which gave the company the right to advertising revenue when its music was played on YouTube.[147] By 2019, creators were having videos taken down or demonetized when Content ID identified even short segments of copyrighted music within a much longer video, with different levels of enforcement depending on the record label.[148] Experts noted that some of these clips said qualified for fair use.[148]

Content ID

[edit]

In June 2007, YouTube began trials of a system for automatic detection of uploaded videos that infringe copyright. Google CEO Eric Schmidt regarded this system as necessary for resolving lawsuits such as the one from Viacom, which alleged that YouTube profited from content that it did not have the right to distribute.[149] The system, which was initially called "Video Identification"[150][151] and later became known as Content ID,[152] creates an ID File for copyrighted audio and video material, and stores it in a database. When a video is uploaded, it is checked against the database, and flags the video as a copyright violation if a match is found.[153] When this occurs, the content owner has the choice of blocking the video to make it unviewable, tracking the viewing statistics of the video, or adding advertisements to the video.[citation needed]

An independent test in 2009 uploaded multiple versions of the same song to YouTube and concluded that while the system was "surprisingly resilient" in finding copyright violations in the audio tracks of videos, it was not infallible.[154] The use of Content ID to remove material automatically has led to controversy in some cases, as the videos have not been checked by a human for fair use.[155] If a YouTube user disagrees with a decision by Content ID, it is possible to fill in a form disputing the decision.[156] Before 2016, videos were not monetized until the dispute was resolved. Since April 2016, videos continue to be monetized while the dispute is in progress, and the money goes to whoever won the dispute.[157] Should the uploader want to monetize the video again, they may remove the disputed audio in the "Video Manager".[158] YouTube has cited the effectiveness of Content ID as one of the reasons why the site's rules were modified in December 2010 to allow some users to upload videos of unlimited length.[159]

Russia

[edit]

In 2021, two accounts linked to RT DE, the German channel of the Russian state-owned RT network, were removed for breaching YouTube's policies relating to COVID-19.[160] Russia threatened to ban YouTube after the platform deleted two German RT channels in September 2021.[161] Shortly after the Russian invasion of Ukraine in 2022, YouTube removed all channels funded by the Russian state.[162] YouTube expanded the removal of Russian content from its site to include channels described as 'pro-Russian'. In June 2022, the War Gonzo channel run by Russian military blogger and journalist Semyon Pegov was deleted.[163]

In July 2023, YouTube removed the channel of British journalist Graham Phillips, active in covering the war in Donbas from 2014.[164] In August 2023, a Moscow court fined Google 3 million rubles, around $35,000, for not deleting what it said was "fake news about the war in Ukraine".[165] In October 2024, a Russian court fined Google 2 undecillion rubles (equivalent to US$20 decillion) for restricting Russian state media channels on YouTube.[166] State news agency TASS reported that Google is allowed to return to the Russian market only if it complies with the court's decision.[167] Kremlin spokesperson Dmitry Peskov labeled the court decision as "symbolic" and warned Google that it "should not be restricting the actions of our broadcasters on its platform."[168]

April Fools gags

[edit]

YouTube featured an April Fools prank on the site on April 1 of every year from 2008 to 2016. In 2008, all links to videos on the main page were redirected to Rick Astley's music video "Never Gonna Give You Up", a prank known as "rickrolling".[169][170] The next year, when clicking on a video on the main page, the whole page turned upside down, which YouTube claimed was a "new layout".[171] In 2010, YouTube temporarily released a "TEXTp" mode which rendered video imagery into ASCII art letters "in order to reduce bandwidth costs by $1 per second."[172]

The next year, the site celebrated its "100th anniversary" with a range of sepia-toned silent, early 1900s-style films, including a parody of Keyboard Cat.[173] In 2012, clicking on the image of a DVD next to the site logo led to a video about a purported option to order every YouTube video for home delivery on DVD.[174] In 2013, YouTube teamed up with satirical newspaper company The Onion to claim in an uploaded video that the video-sharing website was launched as a contest which had finally come to an end, and would shut down for ten years before being re-launched in 2023, featuring only the winning video. The video starred several YouTube celebrities, including Antoine Dodson. A video of two presenters announcing the nominated videos streamed live for 12 hours.[175][176]

In 2014, YouTube announced that it was responsible for the creation of all viral video trends, and revealed previews of upcoming trends, such as "Clocking", "Kissing Dad", and "Glub Glub Water Dance".[177] The next year, YouTube added a music button to the video bar that played samples from "Sandstorm" by Darude.[178] In 2016, YouTube introduced an option to watch every video on the platform in 360-degree mode with Snoop Dogg.[179]

Services

YouTube Premium (formerly Music Key and YouTube Red) is YouTube's premium subscription service. It offers advertising-free streaming, access to original programming, and background and offline video playback on mobile devices.[180] YouTube Premium was originally announced on November 12, 2014, as "Music Key", a subscription music streaming service, and was intended to integrate with and replace the existing Google Play Music "All Access" service.[181][182][183] On October 28, 2015, the service was relaunched as YouTube Red, offering ad-free streaming of all videos and access to exclusive original content.[184][185][186] As of November 2016, the service has 1.5 million subscribers, with a further million on a free-trial basis.[187] As of June 2017, the first season of YouTube Originals had received 250 million views in total.[188]

YouTube Kids

[edit]

YouTube Kids is an American children's video app developed by YouTube, a subsidiary of Google. The app was developed in response to parental and government scrutiny on the content available to children.[citation needed] The app provides a version of the service oriented towards children, with curated selections of content, parental control features, and filtering of videos deemed inappropriate viewing for children aged under 13, 8 or 5, depending on the age grouping chosen. First released on February 15, 2015, as an Android and iOS mobile app, the app has since been released for LG, Samsung, and Sony smart TVs, as well as for Android TV. On May 27, 2020, it became available on Apple TV. As of September 2019, the app is available in 69 countries, including Hong Kong and Macau, and one province. YouTube launched a web-based version of YouTube Kids on August 30, 2019.[189]

On September 28, 2016, YouTube named Lyor Cohen, the co-founder of 300 Entertainment and former Warner Music Group executive, the Global Head of Music.[190] In early 2018, Cohen began hinting at the possible launch of YouTube's new subscription music streaming service, a platform that would compete with other services such as Spotify and Apple Music.[191] On May 22, 2018, the music streaming platform named "YouTube Music" was launched for people who mostly listen to music on YouTube.[192][193][194]

YouTube Movies & TV

[edit]

YouTube Movies & TV is a video on demand (VOD) service that offers movies and television shows for purchase or rental, depending on availability, along with a selection of movies (encompassing between 100 and 500 titles overall) that are free to stream, with interspersed ad breaks. YouTube began offering free-to-view movie titles to its users in November 2018; selections of new movies are added and others removed, unannounced each month.[195] In March 2021, Google announced plans to gradually deprecate the Google Play Movies & TV app, and eventually migrate all users to the YouTube app's Movies & TV store to view, rent and purchase movies and TV shows (first affecting Roku, Samsung, LG, and Vizio smart TV users on July 15).[196][197] Google Play Movies & TV formally shut down on January 17, 2024, with the web version of that platform migrated to YouTube as an expansion of the Movies & TV store to desktop users. Other functions of Google Play Movies & TV were integrated into the Google TV service.[198]

YouTube Primetime Channels

[edit]

On November 1, 2022, YouTube launched Primetime Channels, a channel store platform offering third-party subscription streaming add-ons sold a la carte through the YouTube website and app, competing with similar subscription add-on stores operated by Apple, Prime Video and Roku. The add-ons can be purchased through the YouTube Movies & TV hub or through the official YouTube channels of the available services; subscribers of YouTube TV add-ons that are sold through Primetime Channels can also access their content via the YouTube app and website. A total of 34 streaming services (including Paramount+, Showtime, Starz, MGM+, AMC+ and ViX+) were initially available for purchase.[199][200]

NFL Sunday Ticket, as part of a broader residential distribution deal with Google signed in December 2022 that also made it available to YouTube TV subscribers, was added to Primetime Channels as a standalone add-on on August 16, 2023.[201][202] The ad-free tier of Max was added to Primetime Channels on December 12, 2023, coinciding with YouTube TV converting its separate HBO (for base plan subscribers) and HBO Max (for all subscribers) linear/VOD add-ons into a single combined Max offering.[203][204][note 1]

YouTube TV

[edit]

On February 28, 2017, in a press announcement held at YouTube Space Los Angeles, YouTube announced YouTube TV, an over-the-top MVPD-style subscription service that would be available for United States customers at a price of US$65 per month. Initially launching in five major markets (New York City, Los Angeles, Chicago, Philadelphia and San Francisco) on April 5, 2017,[205][206] the service offers live streams of programming from the five major broadcast networks (ABC, CBS, The CW, Fox and NBC, along with selected MyNetworkTV affiliates and independent stations in certain markets), as well as approximately 60 cable channels owned by companies such as The Walt Disney Company, Paramount Global, Fox Corporation, NBCUniversal, Allen Media Group and Warner Bros. Discovery (including among others Bravo, USA Network, Syfy, Disney Channel, CNN, Cartoon Network, E!, Fox Sports 1, Freeform, FX and ESPN).[207][208]

Subscribers can receive premium cable channels (including HBO (via a combined Max add-on that includes in-app and log-in access to the service), Cinemax, Showtime, Starz and MGM+) and other subscription services (such as NFL Sunday Ticket, MLB.tv, NBA League Pass, Curiosity Stream and Fox Nation) as optional add-ons for an extra fee, and can access YouTube Premium original content.[207][208] In September 2022, YouTube TV began allowing customers to purchase most of its premium add-ons (excluding certain services such as NBA League Pass and AMC+) without an existing subscription to its base package.[209]

YouTube Go

[edit]
Logo of YouTube Go

In September 2016, YouTube Go was announced,[210] as an Android app created for making YouTube easier to access on mobile devices in emerging markets. It was distinct from the company's main Android app and allowed videos to be downloaded and shared with other users. It also allowed users to preview videos, share downloaded videos through Bluetooth, and offered more options for mobile data control and video resolution.[211]

In February 2017, YouTube Go was launched in India, and expanded in November 2017 to 14 other countries, including Nigeria, Indonesia, Thailand, Malaysia, Vietnam, the Philippines, Kenya, and South Africa.[212][213] On February 1, 2018, it was rolled out in 130 countries worldwide, including Brazil, Mexico, Turkey, and Iraq. Before it shut down, the app was available to around 60% of the world's population.[214][215] In May 2022, Google announced that they would be shutting down YouTube Go in August 2022.[216]

YouTube Shorts

[edit]

In September 2020, YouTube announced that it would be launching a beta version of a new platform of 15-second videos, similar to TikTok, called YouTube Shorts.[217][218] The platform was first tested in India and later expanded to other countries, including the United States in March 2021, with videos now able to be up to 1 minute long.[219] The platform is not a standalone app, but is integrated into the main YouTube app. Like TikTok, it gives users access to built-in creative tools, including the possibility of adding licensed music to their videos.[220] The platform had its global beta launch on July 13, 2021.[221]

YouTube Stories

[edit]

In 2018, YouTube started testing a new feature initially called "YouTube Reels".[222] The feature was nearly identical to Instagram Stories and Snapchat Stories. YouTube later renamed the feature "YouTube Stories". It was only available to creators who had more than 10,000 subscribers and could only be posted/seen in the YouTube mobile app.[223] On May 25, 2023, YouTube announced that they would be shutting down this feature on June 26, 2023.[224][225]

YouTube VR

[edit]

In November 2016, YouTube released YouTube VR, a dedicated version with an interface for VR devices, for Google's Daydream mobile VR platform on Android.[226] In November 2018, YouTube VR was released on the Oculus Store for the Oculus Go headset.[226] YouTube VR was updated since for compatibility with successive Quest devices, and was ported to Pico 4.[227]

YouTube VR allows for access to all YouTube-hosted videos, but particularly supports headset access for 360° and 180°-degree video (both in 2D and stereoscopic 3D). Starting with the Oculus Quest, the app was updated for compatibility with mixed-reality passthrough modes on VR headsets. In April 2024, YouTube VR was updated to support 8K SDR video on Meta Quest 3.[228]

Playables

[edit]

In 2010, YouTube added Snake as a hidden game inside of their video player.[229] In May 2024, YouTube introduced Playables, a set of around 75 free-to-play games that can be played on the platform.[230]

Automatic language dubbing

[edit]

In December 2024, YouTube added the functionality of automatic language dubbing, which uses AI to produce translations of videos into different languages.[231][232][233][234]

Criticism and controversies

[edit]

YouTube, a video sharing platform, has faced various criticisms over the years, particularly regarding content moderation, offensive content, and monetization. YouTube has faced criticism over aspects of its operations,[235] its recommendation algorithms perpetuating videos that promote conspiracy theories and falsehoods,[236] hosting videos ostensibly targeting children but containing violent or sexually suggestive content involving popular characters,[237] videos of minors attracting pedophilic activities in their comment sections,[238] and fluctuating policies on the types of content that is eligible to be monetized with advertising.[235]

YouTube has also been blocked by several countries. As of 2018, public access to YouTube was blocked by countries including China, North Korea, Iran, Turkmenistan,[239] Uzbekistan,[240][241] Tajikistan, Eritrea, Sudan and South Sudan.

Privacy concerns

[edit]

Since its founding in 2005, the American video-sharing website YouTube has been faced with a growing number of privacy issues, including allegations that it allows users to upload unauthorized copyrighted material and allows personal information from young children to be collected without their parents' consent.

In September 2024, the Federal Trade Commission released a report summarizing 9 company responses (including from YouTube) to orders made by the agency pursuant to Section 6(b) of the Federal Trade Commission Act of 1914 to provide information about user and non-user data collection (including of children and teenagers) and data use by the companies that found that the companies' user and non-user data practices put individuals vulnerable to identity theft, stalking, unlawful discrimination, emotional distress and mental health issues, social stigma, and reputational harm.[242][243][244]

Censorship and bans

[edit]

YouTube has been censored, filtered, or banned for a variety of reasons, including:[245]

  • Limiting public access and exposure to content that may ignite social or political unrest.
  • Preventing criticism of a ruler (e.g. in North Korea), government (e.g. in China) or its actions (e.g. in Morocco), government officials (e.g. in Turkey and Libya), or religion (e.g. in Pakistan).
  • Morality-based laws, e.g. in Iran.

Access to specific videos is sometimes prevented due to copyright and intellectual property protection laws (e.g. in Germany), violations of hate speech, and preventing access to videos judged inappropriate for youth,[246] which is also done by YouTube with the YouTube Kids app and with "restricted mode".[247] Businesses, schools, government agencies, and other private institutions often block social media sites, including YouTube, due to its bandwidth limitations[248][249] and the site's potential for distraction.[245][250]

As of 2018, public access to YouTube is blocked in many countries, including China, North Korea, Iran, Turkmenistan,[251] Uzbekistan,[252][253] Tajikistan, Eritrea, Sudan and South Sudan. In some countries, YouTube is blocked for more limited periods of time, such as during periods of unrest, the run-up to an election, or in response to upcoming political anniversaries. In cases where the entire site is banned due to one particular video, YouTube will often agree to remove or limit access to that video in order to restore service.[245]

Reports emerged that since October 2019, comments posted with Chinese characters insulting the Chinese Communist Party (共匪 "communist bandit" or 五毛 "50 Cent Party", referring to state-sponsored commentators) were being automatically deleted within 15 seconds.[254] Specific incidents where YouTube has been blocked include:

  • Thailand blocked access in April 2007 over a video said to be insulting the Thai king.[255]
  • Morocco blocked access in May 2007, possibly as a result of videos critical of Morocco's occupation of Western Sahara.[256] YouTube became accessible again on May 30, 2007, after Maroc Telecom unofficially announced that the denied access to the website was a mere "technical glitch".[257]
  • Turkey blocked access between 2008 and 2010 after controversy over videos deemed insulting to Mustafa Kemal Atatürk.[258][259][260] In November 2010, a video of the Turkish politician Deniz Baykal caused the site to be blocked again briefly, and the site was threatened with a new shutdown if it did not remove the video.[261] During the two and a half-year block of YouTube, the video-sharing website remained the eighth-most-accessed site in Turkey.[262][263] In 2014, Turkey blocked the access for the second time, after "a high-level intelligence leak".[264][265][266]
  • Pakistan blocked access on February 23, 2008, because of "offensive material" towards the Islamic faith, including display of the Danish cartoons of Muhammad.[267] This led to a near global blackout of the YouTube site for around two hours, as the Pakistani block was inadvertently transferred to other countries. On February 26, 2008, the ban was lifted after the website had removed the objectionable content from its servers at the request of the government.[268][269] Many Pakistanis circumvented the three-day block by using virtual private network software.[270] In May 2010, following the Everybody Draw Mohammed Day, Pakistan again blocked access to YouTube, citing "growing sacrilegious content".[271] The ban was lifted on May 27, 2010, after the website removed the objectionable content from its servers at the request of the government. However, individual videos deemed offensive to Muslims posted on YouTube will continue to be blocked.[272][273] Pakistan again placed a ban on YouTube in September 2012, after the site refused to remove the film Innocence of Muslims. The ban was lifted in January 2016 after YouTube launched a Pakistan-specific version.[274]
  • Libya blocked access on January 24, 2010, because of videos that featured demonstrations in the city of Benghazi by families of detainees who were killed in Abu Salim prison in 1996, and videos of family members of Libyan leader Muammar Gaddafi at parties. The blocking was criticized by Human Rights Watch.[275] In November 2011, after the Libyan Civil War, YouTube was once again allowed in Libya.[276]
  • Afghanistan, Bangladesh, Pakistan, and Sudan blocked access in September 2012 following controversy over a 14-minute trailer for the film Innocence of Muslims which had been posted on the site.[277][278][279][280][281] A court in the southern Russian Republic of Chechnya ruled that Innocence of Muslims should be banned.[282] In Libya and Egypt, it was blamed for violent protests. YouTube stated: "This video—which is widely available on the Web—is clearly within our guidelines and so will stay on YouTube. However, given the very difficult situation in Libya and Egypt we have temporarily restricted access in both countries."[283][284]
  • Following the Russian invasion of Ukraine in February 2022, YouTube announced on March 1 the immediate removal of RT (and other Russian government-funded outlets) from its platform in Europe. The removal was soon expanded globally.[285] From late 2024, users across Russia started experiencing sharp declines in YouTube loading speeds.[286]

Social impact

[edit]

Private individuals,[287] as well as large production corporations,[288] have used YouTube to grow their audiences. Indie creators have built grassroots followings numbering in the thousands at very little cost or effort, while mass retail and radio promotion proved problematic.[287] Concurrently, old media celebrities moved into the website at the invitation of a YouTube management that witnessed early content creators accruing substantial followings and perceived audience sizes potentially larger than that attainable by television.[288] While YouTube's revenue-sharing "Partner Program" made it possible to earn a substantial living as a video producer—its top five hundred partners each earning more than $100,000 annually[289] and its ten highest-earning channels grossing from $2.5 million to $12 million[290]—in 2012 CMU business editor characterized YouTube as "a free-to-use ... promotional platform for the music labels."[291] In 2013, Katheryn Thayer of Forbes asserted that digital-era artists' work must not only be of high quality, but must elicit reactions on the YouTube platform and social media.[292] Videos of the 2.5% of artists categorized as "mega", "mainstream" and "mid-sized" received 90.3% of the relevant views on YouTube and Vevo in that year.[293] By early 2013, Billboard had announced that it was factoring YouTube streaming data into calculation of the Billboard Hot 100 and related genre charts.[294]

Observing that face-to-face communication of the type that online videos convey has been "fine-tuned by millions of years of evolution", TED curator Chris Anderson referred to several YouTube contributors and asserted that "what Gutenberg did for writing, online video can now do for face-to-face communication."[295] Anderson asserted that it is not far-fetched to say that online video will dramatically accelerate scientific advance, and that video contributors may be about to launch "the biggest learning cycle in human history."[295] In education, for example, the Khan Academy grew from YouTube video tutoring sessions for founder Salman Khan's cousin into what Forbes' Michael Noer called "the largest school in the world", with technology poised to disrupt how people learn.[296] YouTube was awarded a 2008 George Foster Peabody Award,[297] the website being described as a Speakers' Corner that "both embodies and promotes democracy."[298] The Washington Post reported that a disproportionate share of YouTube's most-subscribed channels feature minorities, contrasting with mainstream television in which the stars are largely white.[299] A Pew Research Center study reported the development of "visual journalism", in which citizen eyewitnesses and established news organizations share in content creation.[300] The study also concluded that YouTube was becoming an important platform by which people acquire news.[301]

YouTube has enabled people to more directly engage with government, such as in the CNN/YouTube presidential debates (2007) in which ordinary people submitted questions to U.S. presidential candidates via YouTube video, with a techPresident co-founder saying that Internet video was changing the political landscape.[302] Describing the Arab Spring (2010–2012), sociologist Philip N. Howard quoted an activist's succinct description that organizing the political unrest involved using "Facebook to schedule the protests, Twitter to coordinate, and YouTube to tell the world."[303] In 2012, more than a third of the U.S. Senate introduced a resolution condemning Joseph Kony 16 days after the "Kony 2012" video was posted to YouTube, with resolution co-sponsor Senator Lindsey Graham remarking that the video "will do more to lead to (Kony's) demise than all other action combined."[304]

Prominent YouTube content creators met at the White House with U.S. President Obama to discuss how government could better connect with the "YouTube generation".[305][306]

Conversely, YouTube has also allowed government to more easily engage with citizens, the White House's official YouTube channel being the seventh top news organization producer on YouTube in 2012[307] and in 2013 a healthcare exchange commissioned Obama impersonator Iman Crosson's YouTube music video spoof to encourage young Americans to enroll in the Affordable Care Act (Obamacare)-compliant health insurance.[308] In February 2014, U.S. President Obama held a meeting at the White House with leading YouTube content creators not only to promote awareness of Obamacare[309] but more generally to develop ways for government to better connect with the "YouTube Generation".[305] Whereas YouTube's inherent ability to allow presidents to directly connect with average citizens was noted, the YouTube content creators' new media savvy was perceived necessary to better cope with the website's distracting content and fickle audience.[305]

Some YouTube videos have themselves had a direct effect on world events, such as Innocence of Muslims (2012) which spurred protests and related anti-American violence internationally.[310] TED curator Chris Anderson described a phenomenon by which geographically distributed individuals in a certain field share their independently developed skills in YouTube videos, thus challenging others to improve their own skills, and spurring invention and evolution in that field.[295] Journalist Virginia Heffernan stated in The New York Times that such videos have "surprising implications" for the dissemination of culture and even the future of classical music.[311]

A 2017 article in The New York Times Magazine posited that YouTube had become "the new talk radio" for the far right.[312] Almost a year before YouTube's January 2019 announcement that it would begin a "gradual change" of "reducing recommendations of borderline content and content that could misinform users in harmful ways",[313] Zeynep Tufekci had written in The New York Times that, "(g)iven its billion or so users, YouTube may be one of the most powerful radicalizing instruments of the 21st century".[314] Under YouTube's changes to its recommendation engine, the most-recommended channel evolved from conspiracy theorist Alex Jones (2016) to Fox News (2019).[315] According to a 2020 study, viewership of far-right videos on YouTube peaked in 2017 and "a growing body of journalistic evidence" suggested that YouTube was radicalizing young men through its recommendation engine, but that such evidence was "fraught with a bias towards sensationalism". It also found more "mainstream-adjacent Conservative creators" gaining over alt-right and extremist videos by 2020.[316] A 2022 study found that "despite widespread concerns that YouTube's algorithms send people down 'rabbit holes' with recommendations to extremist videos, little systematic evidence exists to support this conjecture", and that such exposure was "heavily concentrated among a small group of people with high prior levels of gender and racial resentment."[317] A 2024 study by the Institute for Strategic Dialogue found that YouTube frequently recommended Christian videos and right-leaning and culturally conservative "culture war" videos by Fox News and male lifestyle influencers to accounts that did not show an interest in such topics.[318]

The Legion of Extraordinary Dancers[319] and the YouTube Symphony Orchestra[320] selected their membership based on individual video performances.[295][320] Further, the cyber-collaboration charity video "We Are the World 25 for Haiti (YouTube edition)" was formed by mixing performances of 57 globally distributed singers into a single musical work,[321] with The Tokyo Times noting the "We Pray for You" YouTube cyber-collaboration video as an example of a trend to use crowdsourcing for charitable purposes.[322] The anti-bullying It Gets Better Project expanded from a single YouTube video directed to discouraged or suicidal LGBT teens,[323] that within two months drew video responses from hundreds including U.S. President Barack Obama, Vice President Biden, White House staff, and several cabinet secretaries.[324] Similarly, in response to fifteen-year-old Amanda Todd's video "My story: Struggling, bullying, suicide, self-harm", legislative action was undertaken almost immediately after her suicide to study the prevalence of bullying and form a national anti-bullying strategy.[325] In May 2018, after London Metropolitan Police claimed that drill music videos glamorizing violence gave rise to gang violence, YouTube deleted 30 videos.[326]

Finances

[edit]

Prior to 2020, Google did not provide detailed figures for YouTube's running costs, and YouTube's revenues in 2007 were noted as "not material" in a regulatory filing.[327] In June 2008, a Forbes magazine article projected the 2008 revenue at $200 million, noting progress in advertising sales.[328] In 2012, YouTube's revenue from its ads program was estimated at $3.7 billion.[329] In 2013, it nearly doubled and estimated to hit $5.6 billion according to e-Marketer,[329][330] while others estimated $4.7 billion.[329] The vast majority of videos on YouTube are free to view and supported by advertising.[66] In May 2013, YouTube introduced a trial scheme of 53 subscription channels with prices ranging from $0.99 to $6.99 a month.[331] The move was seen as an attempt to compete with other providers of online subscription services such as Netflix, Amazon Prime, and Hulu.[66]

Google first published exact revenue numbers for YouTube in February 2020 as part of Alphabet's 2019 financial report. According to Google, YouTube had made US$15.1 billion in ad revenue in 2019, in contrast to US$8.1 billion in 2017 and US$11.1 billion in 2018. YouTube's revenues made up nearly 10% of the total Alphabet revenue in 2019.[332][333] These revenues accounted for approximately 20 million subscribers combined between YouTube Premium and YouTube Music subscriptions, and 2 million subscribers to YouTube TV.[334] YouTube had $29.2 billion ads revenue in 2022, up by $398 million from the prior year.[335] In Q2 2024, ad revenue rose to $8.66 billion, up 13% on Q1.[336]

Partnership with corporations

[edit]

YouTube entered into a marketing and advertising partnership with NBC in June 2006.[337] In March 2007, it struck a deal with the BBC for three channels with BBC content, one for news and two for entertainment.[338] In November 2008, YouTube reached an agreement with MGM, Lions Gate Entertainment, and CBS, allowing the companies to post full-length films and television episodes on the site, accompanied by advertisements in a section for U.S. viewers called "Shows". The move was intended to create competition with websites such as Hulu, which features material from NBC, Fox, and Disney.[339][340] In November 2009, YouTube launched a version of "Shows" available to UK viewers, offering around 4,000 full-length shows from more than 60 partners.[341] In January 2010, YouTube introduced a film rentals service,[342] available in many countries, and TV shows can be bought in several countries.[343][344] The service offers over 6,000 films.[345]

2017 advertiser boycott

[edit]

In March 2017, the government of the United Kingdom pulled its advertising campaigns from YouTube, after reports that its ads had appeared on videos containing extremist content. The government demanded assurances that its advertising would "be delivered safely and appropriately". The Guardian newspaper, as well as other major British and U.S. brands, similarly suspended their advertising on YouTube in response to their advertising appearing near offensive content. Google stated that it had "begun an extensive review of our advertising policies and have made a public commitment to put in place changes that give brands more control over where their ads appear".[346][347]

In early April 2017, the YouTube channel h3h3Productions presented evidence claiming that a Wall Street Journal article had fabricated screenshots showing major brand advertising on an offensive video containing Johnny Rebel music overlaid on a Chief Keef music video, citing that the video itself had not earned any ad revenue for the uploader. The video was retracted after it was found that the ads had been triggered by the use of copyrighted content in the video.[348][349] On April 6, 2017, YouTube announced that to "ensure revenue only flows to creators who are playing by the rules", it would change its practices to require that a channel undergo a policy compliance review, and have at least 10,000-lifetime views, before they may join the YouTube Partner Program.[350]

YouTuber earnings

[edit]
Total annual earnings of the top ten YouTuber accounts, and the income of the single highest-earning account for 2017

In May 2007, YouTube launched its Partner Program (YPP), a system based on AdSense which allows the uploader of the video to share the revenue produced by advertising on the site.[351] YouTube typically takes 45 percent of the advertising revenue from videos in the Partner Program, with 55 percent going to the uploader.[352][353] There are over two million members of the YouTube Partner Program.[354] According to TubeMogul, in 2013 a pre-roll advertisement on YouTube (one that is shown before the video starts) cost advertisers on average $7.60 per 1000 views. Usually, no more than half of the eligible videos have a pre-roll advertisement, due to a lack of interested advertisers.[355]

YouTube's policies restrict certain forms of content from being included in videos being monetized with advertising, including videos containing violence, strong language, sexual content, "controversial or sensitive subjects and events, including subjects related to war, political conflicts, natural disasters and tragedies, even if graphic imagery is not shown" (unless the content is "usually newsworthy or comedic and the creator's intent is to inform or entertain"),[356] and videos whose user comments contain "inappropriate" content.[357]

In 2013, YouTube introduced an option for channels with at least a thousand subscribers to require a paid subscription for viewers to watch videos.[358][359] In April 2017, YouTube set an eligibility requirement of 10,000 lifetime views for a paid subscription.[360] On January 16, 2018, the eligibility requirement for monetization was changed to 4,000 hours of watch-time within the past 12 months and 1,000 subscribers.[360] The move was seen as an attempt to ensure that videos being monetized did not lead to controversy, but was criticized for penalizing smaller YouTube channels.[361] YouTube Play Buttons, a part of the YouTube Creator Rewards, are a recognition by YouTube of its most popular channels.[362] The trophies made of nickel plated copper-nickel alloy, golden plated brass, silver plated metal, ruby, and red tinted crystal glass are given to channels with at least one hundred thousand, a million, ten million, fifty million subscribers, and one hundred million subscribers, respectively.[363][364]

YouTube's policies on "advertiser-friendly content" restrict what may be incorporated into videos being monetized; this includes strong violence, language,[365] sexual content, and "controversial or sensitive subjects and events, including subjects related to war, political conflicts, natural disasters and tragedies, even if graphic imagery is not shown", unless the content is "usually newsworthy or comedic and the creator's intent is to inform or entertain".[366] In September 2016, after introducing an enhanced notification system to inform users of these violations, YouTube's policies were criticized by prominent users, including Philip DeFranco and Vlogbrothers. DeFranco argued that not being able to earn advertising revenue on such videos was "censorship by a different name". A YouTube spokesperson stated that while the policy itself was not new, the service had "improved the notification and appeal process to ensure better communication to our creators".[367][368][369] Boing Boing reported in 2019 that LGBT keywords resulted in demonetization.[370] In the United States as of November 2020, and June 2021 worldwide,[371] YouTube reserves the right to monetize any video on the platform, even if their uploader is not a member of the YouTube Partner Program. This will occur on channels whose content is deemed "advertiser-friendly", and all revenue will go directly to Google without any share given to the uploader.[372]

[edit]

The majority of YouTube's advertising revenue goes to the publishers and video producers who hold the rights to their videos; the company retains 45% of the ad revenue.[373] In 2010, it was reported that nearly a third of the videos with advertisements were uploaded without permission of the copyright holders. YouTube gives an option for copyright holders to locate and remove their videos or to have them continue running for revenue.[374] In May 2013, Nintendo began enforcing its copyright ownership and claiming the advertising revenue from video creators who posted screenshots of its games.[375] In February 2015, Nintendo agreed to share the revenue with the video creators through the Nintendo Creators Program.[376][377][378] On March 20, 2019, Nintendo announced on Twitter that the company will end the Creators program. Operations for the program ceased on March 20, 2019.[379][380]

On February 13, 2005, Jawed Karim emailed Chad Hurley and Steve Chen with the subject line "video idea," referring to the concept as "Video H or N" (alluding to a video version of Hot or Not), demonstrating the product vision just prior to the domain registration. YouTube was founded on February 14, 2005, when its domain was registered by , , and , three former employees who had met while working there. The trio, having benefited from PayPal's acquisition by , sought to address the challenges of sharing video content online, inspired by personal experiences such as Karim's difficulty in distributing clips from a dinner date and broader frustrations following events like the 2004 halftime show , where clips were hard to access and share. Initially conceived as a video-dating site, the project pivoted to a general video-sharing platform after recognizing broader demand. The platform's first video, "," was uploaded by Karim on April 23, 2005, featuring an 18-second clip of him at the commenting on elephants' trunks. Early development occurred in a garage in , with the site launching publicly later that spring, allowing users to upload, share, and view videos via a simple web interface supporting formats like . Features emphasized ease of use, including embedding videos on other sites, which facilitated rapid dissemination. Growth accelerated in late 2005 with viral content driving traffic. In September 2005, a Nike advertisement featuring became the first video to reach one million views, highlighting the platform's potential for viral spread. The December 17, 2005, "" digital short "Lazy Sunday," featuring and , was uploaded despite NBC's restrictions, garnering millions of views and marking the first major TV clip to achieve virality on YouTube, which pressured broadcasters and boosted the site's visibility. By December 2005, YouTube averaged two million daily video views. Into 2006, uploads surged, reaching approximately 65,000 new videos per day by July, with the site becoming one of the fastest-growing on the web amid increasing adoption.

Acquisition by Google and early expansion (2006–2009)

Google announced its acquisition of YouTube on , 2006, agreeing to purchase the company for $1.65 billion in stock. The deal, which represented 's largest acquisition to date, was structured as an all-stock transaction and received approval from both companies' boards, with closure expected in the fourth quarter of 2006. The acquisition aimed to bolster 's position in online video by integrating YouTube's platform with 's search and advertising technologies, though YouTube continued to operate semi-independently post-purchase. Following the acquisition, YouTube experienced rapid user growth, reaching approximately 160 million monthly unique visitors by 2008 and expanding to 250 million by 2009. Video views surged, with the platform handling tens of millions of daily views in late and scaling to support broader traffic under Google's resources. This period marked early efforts in , including the launch of localized versions in multiple countries starting in , which facilitated content adaptation and regional partnerships to address global demand. Key features introduced during this era included enhanced user profiles with personalization options in mid-2006, followed by subscriptions allowing users to follow channels, full-screen video playback, and a 1-to-5 star persisting through 2009. In 2009, YouTube integrated logins for seamless access, began offering high-definition (HD) video streaming, and experimented with premium content partnerships, signaling a shift toward monetization while merging with Google Video's library in June to consolidate video assets. These developments, supported by Google's , addressed scalability issues like bandwidth demands and concerns through improved tools.

Scaling and "Broadcast Yourself" era (2010–2013)

During this period, YouTube experienced explosive growth, reaching approximately 800 million monthly unique visitors by 2012 and surpassing 1 billion in March 2013. Daily video views hit 4 billion by January 2012, reflecting a 25% increase from the prior eight months, while monthly video watch time exceeded 4 billion hours by 2012. Upload rates intensified to 60 hours of content per minute by early 2012, underscoring the platform's transition from niche video sharing to a dominant global media distributor. The "Broadcast Yourself" slogan, emblematic of YouTube's user-generated ethos since its early years, continued to define the era, promoting amateur creators amid this surge. To accommodate scaling demands, engineers prioritized simplicity in , employing basic tools with loose guarantees rather than over-engineered systems, which enabled handling of petabyte-scale and high concurrency without initial over-specification. This approach addressed challenges like video , search indexing, and (CDN) expansion, as traffic volumes strained servers but benefited from Google's computational resources post-acquisition. Key feature rollouts enhanced accessibility and functionality. In April 2011, YouTube integrated directly into the platform, initially for select partners before broader access, enabling real-time broadcasts that amplified user engagement. October 2011 saw the launch of the Original Channels initiative, a $100 million Google-funded program creating over 100 premium channels across categories like , fitness, and , partnering with entities such as and personalities including to blend professional production with the site's democratic roots. These developments marked a pivot toward curated content while sustaining the core appeal of individual broadcasting, though they introduced tensions between organic uploads and incentivized professionalism. By 2013, full live-streaming democratization further embedded YouTube in events like music performances and , solidifying its infrastructure for sustained hypergrowth.

Challenges under Susan Wojcicki (2014–2023)

During 's tenure as CEO, YouTube faced significant advertiser backlash in 2017, known as the "Adpocalypse," after major brands discovered their ads appearing alongside videos containing , , or inappropriate content, such as terrorist or offensive material. This prompted companies like , Verizon, and to pause or pull advertising spending, resulting in estimated revenue losses for in the hundreds of millions of dollars. In response, YouTube implemented stricter automated demonetization tools and hired thousands of human reviewers, but these measures led to over-censorship complaints from creators whose non-controversial videos were flagged. Creator discontent escalated with vague and inconsistently applied policies introduced around 2016–2017, which demonetized videos for , , or "controversial" topics, even in educational or gaming contexts, causing sudden revenue drops for thousands of channels. Prominent YouTubers like publicly criticized the process as opaque and punitive, with some channels losing entire monetization eligibility for months due to algorithmic errors. By 2019, these policies had demonetized a significant portion of content, prompting widespread backlash and migrations to alternative platforms, as creators argued the rules prioritized advertiser sensitivity over platform openness. Content moderation emerged as a core challenge, with YouTube removing millions of videos for violations including and , but facing accusations of uneven enforcement that disproportionately targeted conservative or dissenting voices. Wojcicki defended retaining some "controversial or offensive" content to preserve free speech, yet the platform banned high-profile figures like in for repeated policy breaches, drawing claims of selective from right-leaning commentators. Studies during this period indicated algorithmic recommendations could amplify extremist content for certain users, particularly right-leaning ones, exacerbating concerns while fueling perceptions of . The intensified moderation pressures, as YouTube adopted aggressive policies in 2020 to remove content deemed "medically unsubstantiated," including discussions of alternative treatments or vaccine skepticism, resulting in over 1 million video removals by September . Wojcicki emphasized these actions as necessary to combat harmful , but critics, including some medical professionals, argued the definitions were overly broad and suppressed legitimate debate, with empirical data showing persistent spread of flagged narratives despite removals. This era highlighted tensions between imperatives and platform neutrality, as YouTube's reliance on automated systems and third-party fact-checkers—often from ideologically aligned institutions—drew scrutiny for potential overreach.

Developments under Neal Mohan (2023–present)

Neal Mohan assumed the role of YouTube's CEO on February 16, 2023, succeeding Susan Wojcicki, with a background as the platform's Chief Product Officer where he oversaw expansions into streaming services, Shorts, and music. In his initial priorities outlined in March 2023, Mohan emphasized creator success through enhanced monetization, future-oriented investments in AI and short-form video, and community protection via improved safety measures. Under Mohan's leadership, YouTube achieved revenue growth, with rising from $31.5 billion in 2023 to $36.1 billion in 2024, a 14.6% increase, driven by expansions in and subscriptions. The platform maintained approximately 2.5 billion monthly active users as of early 2025, with reaching over 200 billion daily views, reflecting sustained engagement in short-form content. The YouTube Partner Program distributed over $70 billion cumulatively to creators by early 2025, including new revenue-sharing models for that mirrored long-form video payouts, building on over $100 billion paid to creators, artists, and media companies in the past four years. Mohan prioritized AI integration as a "creative copilot" for creators, introducing tools for , auto-tagging product placements, and enhanced recommendations while addressing concerns over generative AI's role in content authenticity. He emphasized AI as a tool to empower creators rather than replace them, with over 1 million channels using YouTube's AI tools daily for features like generating Shorts or music. The platform combats low-quality "AI slop" through AI-powered moderation, labeling requirements, and demotion of spam content. In 2026, YouTube remains a stable and expanding income source for creators despite AI advancements and increasing competition. A major outage began on February 17, 2026, around 7:45 PM ET, affecting hundreds of thousands of users (over 240,000 in the US per Downdetector, with nearly 300,000 total reports), with no confirmed widespread outage reports for Japan on that date despite a US-focused disruption; in Japan, issues were reported on February 18, 2026, starting around 10:00 AM JST (some reports as early as 9:50 AM), including the home screen failing to load with a "problem occurred" message, Shorts tab not functioning, and in some cases inability to play videos, though search and channel subscriptions often worked normally, alongside broader problems such as inability to access the homepage, feeds, and app features, while direct video links often worked. No reports indicate a DDoS attack or hacking; the cause was not confirmed by Google/YouTube. The outage impacted mobile apps including Android and web platforms. Issues were improving by early February 18, 2026, with decreasing reports. Quality, original content continued to thrive amid diversified monetization beyond ads, including shopping integrations, brand deals, fan funding such as Jewels and gifts, and direct commerce in Shorts. Policy updates included a commitment to free speech and creative expression, balancing it with enforcement against harmful content, as articulated in Mohan's 2025 strategic outline. This approach contrasted with prior emphases on stricter moderation, though critics from creator communities alleged persistent algorithmic biases favoring "made-for-kids" or low-effort content, claims Mohan addressed by promising refinements to demonetization and recommendation systems. YouTube expanded into "new TV" paradigms, enhancing with features like Key Plays, multiview, and live integrations, positioning the platform as a competitor to traditional . Creator tools advanced with brand collaboration platforms and premium benefits for subscribers, who numbered over 100 million by mid-2025. Mohan's 2025 "big bets" further targeted cultural centrality through podcasts, live events, and global creator economies, amid ongoing investments in and policies derived from empirical user feedback and .

Platform Features

Core video functionalities

YouTube enables users to original video content through its web interface, mobile applications, and dashboard, with supported file formats including .MOV, ., ., .MPEG4, .MP4, .MPG, ., .WMV, .MPEGPS, .FLV, , , and DNxHR. Upload limits restrict files to a maximum of 256 GB or 12 hours in duration, whichever comes first, though unverified accounts face an initial 15-minute cap per video that requires phone verification to exceed. Creators can add metadata such as titles, descriptions, tags, thumbnails—including multi-language thumbnails introduced in 2025, allowing creators to upload custom, language-specific thumbnails that automatically match the viewer's selected language or audio track, integrated with multi-language audio dubbing tools and requiring manual provision rather than automatic AI translation of existing thumbnails (piloted mid-2025)—and categories during , alongside options for ranging from public to unlisted or private. Video playback occurs via streaming, delivering content in resolutions from 144p to 4320p (8K UHD), with aspect ratios including 16:9, 4:3, and vertical formats for . Adaptive bitrate dynamically adjusts quality based on the viewer's bandwidth to minimize buffering, while playback controls encompass play/pause, seeking via , volume adjustment, fullscreen mode, and speed variation from 0.25x to 2x normal rate. YouTube includes an automatic pause mechanism that detects user inactivity, such as no screen touches or device movement, after a period of time, pausing the video and prompting the user to continue watching if they are still engaged. This feature can interfere with background playback uses, such as listening to music. Common playback issues, such as videos restarting unexpectedly, can often be addressed by disabling browser extensions particularly ad blockers like uBlock Origin or AdBlock, turning off hardware acceleration in browser settings (for example, in Chrome: Settings > System > toggle off "Use hardware acceleration when available" followed by restarting the browser), clearing browser cache and cookies, trying playback in incognito or private mode to isolate extensions, updating the browser or switching to a different one, ensuring a stable internet connection potentially by restarting the router, and for the YouTube mobile app, clearing app cache or data or reinstalling the app. Videos restarting unexpectedly are frequently caused by interfering extensions or browser configurations. YouTube processes uploaded videos into multiple quality tiers, recommending specific bitrates for optimal compression, such as 8 Mbps for at 30 fps or 12 Mbps at 60 fps; for audio in WebM containers, modern streams employ the Opus codec at a 48 kHz sample rate with typical bitrates of ~50 kbps (low), ~70 kbps (medium), and up to ~160 kbps (highest for stereo), while older streams rarely use Vorbis. Core interactions tied to videos include liking or disliking (with dislikes hidden from public view since November 2021), commenting, and via direct links, which support start time parameters using ?t= or &t= in formats such as seconds only (e.g., 90s), minutes and seconds (e.g., 1m30s), or hours minutes seconds (e.g., 1h3m30s), with shortened youtu.be links using ?t= similarly (e.g., 135s), or embed codes that allow integration into external websites and use the ?start= parameter specifying start time in seconds only, subject to Terms of Service restrictions limiting access to personal, non-commercial viewing and listening; embedding via the official player is permitted mainly for non-commercial contexts but prohibits commercial exploitation, such as selling access, placing embeds behind paywalls, or basing primary revenue on embedded content (e.g., ads or subscriptions driven by videos). YouTube's search engine utilizes artificial intelligence, including an AI-powered search results carousel introduced in June 2025 that suggests relevant videos and topic descriptions created by YouTube creators to enhance content discovery. Videos support closed captions in multiple languages, either auto-generated or manually uploaded. As of February 2026, YouTube expanded its artificial intelligence-powered auto-dubbing feature to support 27 languages, making it available to all creators and viewers; automatic dubbing generates translated audio tracks distinct from manual multi-language audio uploads, with features including "Expressive Speech" in 8 languages (English, French, German, Hindi, Indonesian, Italian, Portuguese, Spanish) for better emotional capture, a Preferred Language setting for viewers, and a Lip Sync pilot, alongside ongoing quality improvements and filters to avoid unsuitable content. This applies to spoken content in eligible non-music videos to enhance accessibility for international viewers. Videos also include end screens or cards for linking to other content. These functionalities, foundational since YouTube's launch with the first video upload on April 23, have evolved to handle diverse content types like 360-degree and live streams, though basic upload and playback remain unchanged in principle.

User interface and accessibility

The YouTube user interface on desktop features a central video player with timeline scrubbing, playback controls, and quality settings, accompanied by a right sidebar for recommended videos, playlists, and channel subscriptions. The homepage displays a grid of algorithm-curated recommendations, subscription feeds, and trending sections above a persistent search bar, with the Create button located in the top right corner for uploading videos or accessing YouTube Studio. Mobile app interfaces prioritize vertical scrolling through infinite feeds of Shorts and long-form videos, with a bottom navigation bar accessing Home, Explore, Subscriptions, Inbox, and Library tabs for touch-based interaction. The Create section is typically accessed via a '+' icon in the center of the bottom navigation bar; tapping it allows users to upload videos, create Shorts, or access other creation options. Desktop layouts offer higher information density suitable for mouse navigation, whereas mobile designs emphasize swipe gestures and compact thumbnails to accommodate smaller screens. Recent interface updates, including experiments in 2025 with smaller mobile thumbnails and enlarged desktop video players, have elicited user complaints regarding reduced usability and excessive whitespace, mirroring backlash to the 2024 redesign that prioritized visual spacing over content density. These changes, tested under CEO , aim to align desktop and mobile experiences more closely with app-like simplicity but have disrupted familiar workflows for some power users. Core navigation relies on keyboard shortcuts universally, with search functionality surfacing results in a filtered grid view for videos, channels, and playlists. Users can perform exact match searches by enclosing phrases in double quotes (e.g., "exact phrase here"), use the intitle: operator for exact titles (e.g., intitle:"exact title"), exclude terms with -term, and apply post-search filters such as upload date and video type to prioritize relevant results; however, search results include algorithmic recommendations that cannot be fully disabled. The search bar displays recent search history for users signed into a Google account with search history enabled; non-display commonly stems from lack of sign-in, paused search history, or temporary app/web errors, with no permanent feature removal noted in 2025 or 2026. Signed-out viewing remains available across web, mobile, and other platforms, allowing users to watch videos without an account, though personalized features like recommendations and search history are unavailable; age-restricted content requires sign-in and verification. In February 2025, the "Guest" profile shortcut was removed from TV apps such as Apple TV, Roku, and Fire TV, replaced by a "Use signed out" option that permits viewing without signing in. As of February 18, 2026, guest mode and signed-out viewing have not been discontinued platform-wide. Resolutions include signing in, enabling history via myactivity.google.com under YouTube search settings, clearing app cache, updating the YouTube app, or re-signing in. In January 2026, advanced search tools were updated to include a "Type" filter distinguishing Shorts from long-form videos (VODs), allowing users to exclude Shorts from results, alongside duration filters such as content over 3 minutes; the updates also removed 'Upload Date – Last Hour', 'Sort by Rating', and the option to sort results by upload date, while retaining broader upload date filters such as Today, This Week, This Month, and This Year. TeamYouTube acknowledged user feedback on the removal of the sort by upload date option, noting its usefulness for tracking breaking news, and shared it with the product team. Users signed into multiple Google accounts can switch between them via the "Switch account" feature, which displays associated channels. On the mobile app, this involves opening the app, tapping the profile icon (typically bottom right or top), selecting "Switch account," and choosing from the list; adding a new account uses the "Add account" option followed by sign-in. On the website, users click the profile picture in the top right, select "Switch account," and pick the desired account. As of February 2026, the process remains consistent with prior years, subject to minor UI updates on mobile. YouTube provides accessibility features including automatic speech-to-text captions generated via , available since their 2009 launch with ongoing accuracy improvements, though performance degrades with background noise, accents, or technical terminology. Users can custom closed captions, including advanced styled captions in the proprietary .ytt format supporting colors, positioning, shadows, bold/italic, and other styling options, or enable community contributions for precision, enhancing comprehension for deaf or hard-of-hearing individuals. compatibility supports tools like NVDA and JAWS on desktop, with automatic activation of keyboard navigation for menu traversal, playback control, and comment interaction. On mobile, integration with Android's TalkBack service enables gesture-based audio feedback for blind users, including video descriptions and UI element announcements, while iOS support offers similar haptic and verbal cues. Additional options encompass adjustable playback speeds from 0.25x to 2x, high-contrast themes for low-vision users, and audio descriptions uploadable by creators to narrate visual elements. Despite these tools, empirical limitations persist, such as imperfect auto-caption synchronization and incomplete parsing of dynamic recommendation feeds, underscoring reliance on creator diligence for optimal .

Recommendation algorithm mechanics

YouTube's recommendation algorithm utilizes a two-stage machine learning framework comprising candidate generation and ranking to personalize video suggestions across the homepage, suggested videos, and search results. This system processes billions of daily interactions to predict user preferences, drawing from and content-based approaches embedded in deep neural networks. As of , recommendations accounted for approximately 70% of all video views on the platform. In the candidate generation stage, a deep efficiently retrieves a shortlist of several hundred video candidates from a corpus exceeding hundreds of millions of videos. The model ingests user-specific features, such as derived from the user's recent watch history (typically the last 1,000 views), search queries, demographics, and contextual data like device type and time of day. Video features include metadata for titles, descriptions, and tags. By computing similarities in a shared embedding space—often via dot products or Euclidean distances—the network identifies videos likely to align with the user's latent interests, prioritizing computational efficiency to handle scale. This phase emphasizes over precision, narrowing candidates without exhaustive pairwise comparisons. The subsequent ranking stage employs a separate deep to evaluate the candidate set, assigning scores based on predicted user satisfaction. It incorporates richer signals, primarily watch time percentage and click-through rate (CTR)—the percentage of impressions resulting in clicks—which the algorithm interprets as indicating engaging content, thereby promoting high-CTR videos more prominently in recommendations and search results to increase views, watch time, and ad revenue. Creators optimize thumbnails for CTR via A/B testing, with effective elements including expressive faces and curiosity-driven graphics that boost performance. Additional signals include engagement metrics, viewer history, estimated CTR, expected watch time, likes, dislikes, shares, and post-watch survey responses rated on a 1-5 scale for perceived value. Recommendations build gradually and heavily weigh channel authority, subscriber base, and past performance. Additional factors encompass video freshness, creator authority (derived from historical performance and subscriber metrics), and session-level context to forecast multi-video watch sequences; notably, a creator's personal watch history does not influence recommendations of their channel's videos to other users, affecting only the creator's own homepage and feed, as the system relies on viewer engagement metrics and channel quality. For Shorts, videos receive some initial testing with a seed audience, but views often derive from search, subscriptions, or existing audience rather than pure algorithmic discovery. The model optimizes a weighted logistic objective balancing clicks and watch duration, trained on logged user actions to maximize long-term retention rather than isolated engagements. Over 80 billion such signals inform daily model updates. Content achieving high viewer retention is automatically promoted more broadly to global audiences, irrespective of the initial viewer's location. Core objectives center on delivering "satisfying" content that extends session watch time while adhering to responsibility principles to curb low-quality or harmful recommendations, though users of YouTube Music have reported an emerging issue of AI-generated low-quality music dominating personalized recommendations, comprising a significant portion of suggestions and eliciting calls for AI filtering tools. Watch time per impression serves as a primary proxy for satisfaction, as evidenced by a 20% drop in average views following its prioritization over pure clicks. Evolutions include weighting toward authoritative sources—reducing borderline content views from recommendations to under 1% by —and demotions for misleading thumbnails or tabloid-style videos, yielding measurable watch time gains like 0.5% over 2.5 months in tested cohorts. These adjustments reflect causal interventions to align with viewer value, though empirical critiques note persistent amplification of sensational content due to inherent optimization for prolonged attention.

Content Ecosystem

Video types and production tools

YouTube classifies uploaded videos into standardized categories via its , enabling algorithmic organization and recommendation. These include Film & (ID 1), Autos & Vehicles (ID 2), (ID 10), Pets & Animals (ID 15), Sports (ID 17), Travel & Events (ID 19), Gaming (ID 20), People & Blogs (ID 22), (ID 23), (ID 24), News & Politics (ID 25), Howto & Style (ID 26), (ID 27), Science & Technology (ID 28), and Nonprofits & (ID 29), among others. Creators select these during upload to signal content themes, influencing discoverability, though the platform's algorithm prioritizes user engagement metrics over strict categorization. Among these, gaming content generates the highest traffic volume, accounting for substantial shares of platform engagement due to live streams, walkthroughs, and coverage. Music videos dominate individual view counts, with top entries like "" by exceeding 8 billion views as of 2023, reflecting sustained demand for audio-visual entertainment. Other high-engagement genres include educational tutorials, product reviews, vlogs, and , which collectively drive billions of hours watched annually; for instance, how-to and explainer videos appeal to practical problem-solving, while reaction and challenge formats leverage viral trends for rapid growth. YouTube supports through integrated tools in , a web and mobile dashboard for editing, analytics, and metadata management, allowing creators to trim clips, add captions, and optimize thumbnails without external software. The YouTube Create app extends mobile editing capabilities, incorporating effects, music libraries, and auto-captions for Shorts and long-form content. In 2025, YouTube introduced AI-assisted production features, including Veo 3 for generative video clips from text prompts, AI-powered for scene detection and enhancements, and tools like Ask Studio for brainstorming ideas, aimed at lowering barriers for novice creators while raising concerns over authenticity and over-reliance on . Building on these, as of 2026, YouTube announced features allowing creators to generate Shorts using an AI version of their own likeness, produce games from simple text prompts via the Playables program, and experiment with AI music tools. Additionally, the quizzes feature, introduced in late 2025 or early 2026, enables creators to add interactive quizzes to videos, including auto-generated pop quizzes to enhance viewer engagement. YouTube emphasizes safeguards, including labeling AI-generated content, requiring disclosure of synthetic media, protecting creators' likeness rights, and measures to reduce low-quality "AI slop." User discussions on Reddit reflect mixed feedback, with some viewing quizzes as a monetization tactic causing annoyance and raising concerns about spam or AI-generated quality, while others note potential benefits for engagement. These build on earlier basics like built-in trimming and transitions, but professional creators often supplement with third-party software for advanced effects, as YouTube's tools emphasize over high-end . YouTube's primary copyright enforcement mechanism is , an automated digital fingerprinting system launched in that scans uploaded videos against reference files submitted by copyright owners to detect matches or substantial similarities. When a match is identified, the rights holder receives a Content ID claim, enabling options such as monetizing the video through ad , blocking it worldwide or in specific countries, muting audio, or simply tracking viewership without further action. This system processes billions of videos annually, with claims resulting in over $12 billion paid to rights holders since its inception, including more than $9 billion in recent years amid rising upload volumes. Complementing Content ID, YouTube handles manual copyright infringement claims via the (DMCA) process, where rights holders submit removal requests for unauthorized use, prompting YouTube to expeditiously remove the content to maintain its safe harbor protections under Section 512 of the DMCA. Successful DMCA notices result in copyright strikes against the uploader's account; three strikes within 90 days lead to channel termination. Uploaders can dispute claims through counter-notification, potentially triggering a from the claimant, though most disputes are resolved internally via 's appeal process, which examines factors like but favors initial claims to minimize platform liability. The system's automation has drawn for frequent false positives, where excerpts—such as , , or transformative edits—are flagged due to algorithmic limitations in distinguishing context, leading to erroneous demonetization or blocks that burden creators with disputes. Advocacy groups like the argue that Content ID's design shifts the burden of proof onto users, effectively privatizing enforcement and undermining DMCA's notice-and-takedown balance by preemptively applying claims without judicial oversight. However, YouTube reports that the majority of claims are resolved without removal, and the system has enabled new revenue streams for rights holders by capturing ad income from incorporating licensed material. Empirical data from YouTube's transparency reports indicate that while claim volumes have surged with platform growth, wrongful claims can be retracted by claimants, though creators cite low dispute success rates and repeated claims from the same parties as persistent issues.

Creator monetization pathways

The YouTube Partner Program (YPP) serves as the primary gateway for creators to access official tools, requiring channels to comply with YouTube's policies, including advertiser-friendly content guidelines that prohibit certain themes like excessive or controversial issues to ensure ad eligibility. Eligibility for full YPP participation demands at least 1,000 subscribers, 4,000 valid public watch hours over the prior 12 months, or 10 million valid public Shorts views in the preceding 90 days, alongside factors such as no active Community Guidelines strikes, two-step account verification, and residence in supported countries. An expanded YPP tier, introduced to broaden access, enables fan-funding features at reduced thresholds of 500 subscribers, three valid public uploads in the last 90 days, and either 3,000 watch hours in 12 months or 3 million Shorts views in 90 days. Creators accepted into this expanded tier automatically become eligible for higher-tier features, such as ad revenue sharing, upon meeting the corresponding thresholds without requiring a separate application. Key monetization pathways within YPP include advertising revenue sharing, where creators receive 55% of net ad earnings from display, overlay, and video ads on eligible long-form videos, with revenue calculated after YouTube deducts costs like . Creators also earn from subscriptions, receiving a share of the 45% of net Premium revenue allocated to monetizing creators based on viewer watch time of their content. For , creators get 45% of the Premium revenue pool attributed to Shorts views, distributed proportionally among eligible videos without direct ad splits. Fan-funding mechanisms provide additional streams: channel memberships allow subscribers to pay monthly fees (starting at $0.99, varying by region) for exclusive badges, emojis, and content, with creators retaining approximately 70% after platform fees and applicable taxes. Super Chat, Super Thanks, and Super Stickers enable paid highlights during live streams or premieres and post-video contributions, yielding creators around 70% of proceeds after deductions. Gifts powered by Jewels extend this to eligible vertical live streams, where viewers purchase Jewels to send digital gifts, and creators earn Rubies based on received gifts. The merch shelf integrates by displaying creator-linked products from partners like below videos for channels with 10,000 subscribers or significant views. YouTube Shopping allows eligible creators to tag products from partnered brands or their own stores in videos and descriptions, facilitating commissions on resulting sales, with expansions including direct commerce features in Shorts via shoppable integrations. These pathways are subject to ongoing policy enforcement to maintain eligibility, including avoidance of copyright strikes from using non-royalty-free assets, which result in content removal and can render channels ineligible for YPP. Community Guidelines violations, such as those involving misinformation or hate speech, lead to strikes that jeopardize monetization status. Purchasing fake views or subscribers constitutes artificial engagement, violating policies and potentially causing demonetization or account bans. Channels inactive for six months or more also risk suspension from the YPP. Tightened rules effective July 15, 2025, further restrict monetization for reused clips or low-effort content to prioritize original work. Payouts occur monthly via AdSense once thresholds like $100 in earnings are met, with creators responsible for tax compliance. Monetization continues to diversify beyond ads through enhanced shopping integrations, brand deals, and fan funding options like Jewels and gifts, alongside direct commerce in Shorts. Over the past four years, YouTube has paid over $100 billion to creators, positioning the platform as the most stable for creator businesses amid growing competition and AI advancements. While effective for high-engagement channels, earnings vary widely based on audience size, niche, and geographic factors, with top earners leveraging multiple streams alongside external sponsorships, affiliate marketing, and crowdfunding not covered by YPP.

YouTube provides free subscriptions to individual channels, enabling users to follow creators and receive notifications for new video uploads, premieres, and live streams without any cost. This core feature, available since the platform's in , supports user engagement by curating personalized subscription feeds and allowing bell icon activations for immediate alerts. In addition to free channel subscriptions, YouTube introduced channel memberships in 2018 as a tool for eligible creators. These paid subscriptions, set by creators in tiers typically starting at $4.99 per month and ranging up to higher amounts based on perks offered, grant members access to exclusive content such as members-only videos, live chats, badges, custom emojis, and behind-the-scenes material. Eligibility requires creators to be in the YouTube Partner Program, maintain at least 1,000 subscribers, and operate in supported countries, with YouTube taking a 30% revenue share. YouTube Premium, rebranded from YouTube Red in May 2018, represents the platform's primary ad-free subscription service, bundling access to Premium for over 100 million songs and podcasts. Key features include uninterrupted viewing without advertisements on YouTube and , offline video downloads, background playback on mobile devices, and mode. As of 2025, subscription tiers include:
TierMonthly PriceKey Details

A one-month free trial is offered to new eligible subscribers, with cancellation available anytime. Premium revenue contributes significantly to creator earnings through watch-time shares, though adoption remains a fraction of the platform's over 2.7 billion monthly active users as of 2024. YouTube Music subscribers have reported frustration with the rising presence of AI-generated low-quality music in recommendations, with some indicating up to 60% of suggestions consisting of such content featuring unnatural vocals and repetitive structures; users have called for AI filters, artist blocking, and enhanced discovery tools.

Live and short-form content platforms

YouTube introduced in April 2011, initially restricting access to select partners before expanding availability. This feature enables real-time video broadcasts accessible via web, mobile apps, and encoder software, supporting events such as gaming sessions, Q&A interactions, and public announcements. Key functionalities include live chat for viewer comments, polling for audience input, and moderation tools to manage interactions during streams. Monetization for live streams occurs through ad insertions, Super Chat (viewer-paid message highlights), Super Stickers (animated paid reactions), and channel memberships offering exclusive perks. In September 2025, YouTube announced enhancements like dynamic sponsorship insertions and AI-generated highlight clips to boost creator earnings and retention. By the second quarter of 2025, live content accounted for over 30 percent of daily watch time among logged-in viewers, reflecting its role in driving real-time engagement amid competition from platforms like Twitch. YouTube Shorts, the platform's short-form video offering, launched in beta in in September 2020 and expanded globally by July 2021 to counter TikTok's dominance in vertical, bite-sized content. Creators produce Shorts using in-app tools for recording, , and adding licensed music or effects, with videos limited to 60 seconds (recently extended for select formats) and optimized for mobile scrolling in a dedicated feed. The format supports remixing existing videos, multi-segment clips, and speed controls, fostering viral trends and quick discovery via algorithmic recommendations prioritizing watch completion and replays. As of 2025, Shorts generate over 200 billion daily views and serve more than 2 billion monthly users, with watch time increasing 65 percent year-over-year. Over 52 million channels have uploaded , marking 50 percent annual growth in participating creators, though average engagement rates hover around 5.91 percent, varying by niche and audience retention. shifted from a temporary Shorts Fund to ad in the Partner Program, where creators earn from Shorts Feed ads based on music usage and view attribution, though payouts remain lower per view than long-form videos due to higher volume and shorter durations.

Specialized applications and integrations

YouTube provides the YouTube Data API, which enables developers to integrate core platform functionalities into external applications, including video uploads, playlist management, channel customization, and content search filtered by parameters such as keywords, regions, and upload dates. This API supports JSON-based resource representations for videos, channels, and subscriptions, facilitating use cases like embedding searchable video libraries in custom software or automating content workflows. Developers can access code samples in languages including , Python, and , along with tools like the APIs Explorer for testing requests and a Quota Calculator for managing usage limits. The YouTube Player for Education serves as a specialized embedded player designed for integration into educational technologies, delivering videos without advertisements, external links, or algorithmic recommendations to minimize distractions. It ensures viewer anonymity relative to YouTube's standard tracking and provides enhanced controls compliant with educational standards, allowing institutions to embed content securely in learning management systems. Introduced in 2023 and expanded for creator monetization in June 2025, the player enables when licensed by edtech partners, who pay YouTube for access, with portions directed to content creators based on usage in interactive lessons or supplemental materials. For , the YouTube VR app integrates with headsets such as Meta Quest, transforming standard videos into immersive 3D experiences and supporting native 360-degree and VR-specific content playback. Users access this through dedicated VR storefronts, where the app reimagines the interface as an explorable , though support for certain legacy VR formats like has diminished over time. Third-party automation platforms like , , and Integrately offer no-code integrations connecting YouTube to over 8,000 apps, enabling workflows such as triggering notifications on new uploads or syncing video data with CRM systems. These tools support event-based automations, including hooks for subscriptions and analytics exports, broadening YouTube's utility in business and productivity contexts without requiring direct development. YouTube also integrates with consumer devices including smart TVs, streaming dongles like , and audio systems such as , allowing cross-device continuity for playback and casting via linked Google accounts. Gaming consoles and enterprise-linked services further extend this, though YouTube's API quotas and terms limit high-volume enterprise-scale deployments compared to dedicated video platforms.

Business Model

Revenue generation strategies

YouTube provides free access to its video content through an advertising-supported business model, where targeted ads—tailored based on users' viewing history, Google Ad Settings, and video content—are displayed to generate revenue that supports creators through revenue sharing and funds platform operations. YouTube generates the bulk of its through displayed across its video platform, with ad forming the core of its . In 2024, YouTube's totaled $36.1 billion, representing a 14.6% increase from the prior year. This income derives from various ad formats auctioned via Google's system, including skippable in-stream ads, non-skippable ads, bumper ads, and overlay displays, targeted based on viewer data and content relevance. In April 2024, YouTube launched the campaign "YouTubeで、君の応援歌を。" (#YouTubeで応援), a user-participatory promotion encouraging users to post and share their support songs, featuring themed advertisements with tracks from diverse artists including Kenshi Yonezu, YOASOBI, Vaundy, Mrs. GREEN APPLE, back number, and Aimer. Factors affecting YouTube ad revenue include views, audience location (with higher rates in the US and Europe), engagement metrics, and varying ad rates; niches like tech and AI often yield higher RPM due to strong advertiser interest. In the second quarter of 2025, YouTube ad climbed to $9.8 billion, up 13% year-over-year, driven by growth in short-form content and international markets. The platform shares a portion of this ad revenue with eligible creators through the YouTube Partner Program (YPP), which requires channels to meet thresholds such as 1,000 subscribers and 4,000 watch hours. For long-form videos, creators receive 55% of the allocated ad revenue, while YouTube retains 45%; for , the split reverses to 45% for creators and 55% for the platform. This structure, established to attract high-quality content, has distributed over $70 billion to creators cumulatively, though it exposes YouTube to advertiser pullbacks during economic downturns or content controversies. To diversify beyond ad volatility, YouTube emphasizes subscription services like , which had exceeded 125 million paid subscribers by early 2025. Premium users pay tiered monthly fees—typically $13.99 in the U.S. for individuals—for ad-free access, offline downloads, and integration, generating direct recurring revenue not tied to ad auctions. Creators earn from Premium via a watch-time-based allocation of 55% of net subscription fees attributable to their content. This model supplements ads, with subscriptions contributing meaningfully to creator payouts on channels with strong Premium viewer engagement, though exact platform-level subscription revenue remains bundled in Alphabet's broader Services reporting. Additional streams include fan-funding features and licensing. Tools such as Super Chat, Super Thanks, and channel memberships allow direct viewer payments during lives or for exclusive perks, with YouTube taking a 30% commission after app store fees. , YouTube's automated copyright detection system, enables rights holders to monetize user-uploaded videos incorporating their assets, generating licensing revenue shared between claimants and the platform. Merchandise sales via the video shelf, facilitated through third-party partners, provide another indirect channel, though it constitutes a smaller fraction compared to ads and subscriptions. These mechanisms collectively enhance creator retention and platform stickiness while capturing value from engaged audiences.

Advertising partnerships and disputes

YouTube's primary advertising partnerships operate through integration with , enabling programmatic ad placements such as skippable in-stream ads, bumper ads, and display formats across videos. Creators eligible for the YouTube Partner Program (YPP), launched in December 2007, monetize content by sharing 55% of ad revenue generated from views on their channels, with YouTube retaining 45%. By August 2021, over 2 million creators worldwide participated in the YPP, facilitating direct revenue streams from brand partnerships and sponsored content alongside automated ads. These partnerships emphasize based on viewer , with brands leveraging YouTube's scale to reach demographics underserved by traditional TV. Significant disputes arose in March 2017 when advertisers discovered their ads appearing adjacent to videos promoting , , or , prompting an exodus dubbed the "Adpocalypse." A Wall Street Journal investigation revealed ads funding groups like and white supremacists, leading over 250 organizations, including , Verizon, and , to suspend spending on YouTube and Google's platforms. The issue stemmed from flawed automated ad placement algorithms prioritizing view counts over contextual safety, exacerbated by incidents like PewDiePie's February 2017 videos featuring anti-Semitic content, which severed his affiliation. In response, YouTube implemented stricter advertiser-friendly guidelines, hired thousands of human reviewers, and refined to demonetize or restrict non-compliant videos, though this overcorrected by affecting educational and gaming content lacking overt violations. A second wave hit in early amid reports of interconnected comment networks on children's videos facilitating pedophile grooming, causing brands like , , and to again over failures. YouTube's subsequent policy updates, including expanded restricted mode and age-gating, restored most ad flows within months, but recurring issues highlighted persistent tensions between algorithmic efficiency, creator livelihoods, and advertiser demands for contextual controls.

Financial performance metrics

YouTube's financial performance is predominantly reflected in its , which reports separately in quarterly earnings, supplemented by revenue from subscription services like , though the latter is aggregated under broader subscriptions categories without isolated YouTube-specific breakdowns. Advertising remains the core revenue driver, accounting for the majority of YouTube's contributions to Services segment. Costs associated with content acquisition, , and operations are not allocated solely to YouTube, limiting visibility into platform-specific profitability, though overall margins suggest strong underlying performance amid scaled ad operations. In the second quarter of 2025 (ended June 30), YouTube totaled $9.8 billion, marking a 13% year-over-year increase from $8.7 billion in Q2 2024 and surpassing analyst expectations of $9.6 billion. This growth contributed to Alphabet's total quarterly revenue of $96.4 billion, up 14% year-over-year, with YouTube ads representing about 10% of the consolidated figure. Sequential growth from Q1 2025 was approximately 6.6%, driven by expanded ad formats and viewer engagement. For the full year 2024, YouTube's global reached $36.1 billion, a 14.6% increase from $31.5 billion in 2023, reflecting recovery in digital ad markets post-pandemic and enhancements in ad targeting efficiency. Estimates of total YouTube revenue, incorporating subscriptions, place it at around $54.2 billion for 2024, though official disclosures emphasize ad metrics due to their scale. These figures underscore YouTube's role as a high-growth asset within , with ad revenue consistently outpacing broader industry averages amid competition from platforms like .

Content Moderation

Policy frameworks and guidelines

YouTube's Community Guidelines form the core policy framework governing content on the platform, prohibiting material deemed harmful, dangerous, or deceptive while purporting to balance openness with user safety. These guidelines, enforced since the platform's early years and regularly updated, categorize violations into areas such as spam and scams, sensitive content like or (permitted only in educational, documentary, scientific, or artistic contexts), child safety (strictly banning exploitation or abuse material), and promotion of violent or extremist ideologies. For instance, policies target content that attacks individuals or groups based on protected attributes like race, ethnicity, or , but exclude broad political criticism unless it incites harm. Additional frameworks address misinformation and harmful content, including rules against medical disinformation that contradicts health authorities (e.g., false claims) and election interference, with requirements for contextual information labels rather than outright removal in some cases. In September 2024, YouTube expanded safeguards in Europe to limit repeated algorithmic recommendations of health and fitness videos to teenagers that idealize specific body types, fitness levels, or physical features, developed in consultation with experts to support teen wellbeing. Regulated goods policies restrict promotion of items like , drugs, firearms, and uncertified online gambling sites or apps; violations for gambling content, such as directing viewers to prohibited platforms via unblurred URLs, visible links, logos, or verbal references, result in content removal, strikes, and permanent channel bans for severe or repeated infractions. These policies align with advertiser-friendly guidelines that influence eligibility. In July 2025, YouTube updated advertiser-friendly content rules to expand prohibitions on inappropriate language, potentially affecting broader content visibility. The guidelines emphasize creator responsibility, with violations leading to strikes, video removals, or channel terminations after three strikes within 90 days; an appeals process allows human review of automated or reported decisions. Enforcement relies on for initial detection combined with human moderators, though critics argue the subjective nature of terms like "harmful" enables inconsistent application. Conservative organizations have filed lawsuits alleging ideological bias in enforcement, claiming right-leaning content faces disproportionate demonetization or removal compared to similar left-leaning material, as seen in 2019 litigation by groups like . Conversely, advocacy groups representing LGBTQ+ creators have sued over perceived failures to protect against targeted harassment, highlighting enforcement gaps on both political extremes. YouTube's parent company, , reports quarterly transparency data showing millions of removals annually, but independent analyses suggest user-driven reports amplify biases aligned with moderators' political leanings.

Enforcement technologies and processes

YouTube's enforcement of community guidelines relies on a hybrid system integrating classifiers for initial detection and human reviewers for validation and nuanced judgments. Automated systems, powered by , scan newly uploaded videos in real-time, flagging potential violations across categories such as child safety, , , and . These classifiers, trained on labeled datasets of prior content, achieve high , accounting for 99.5% of initial flaggings leading to removals. In the fourth quarter of 2024, automated detection prompted the removal of approximately 9.12 million videos, compared to 266,000 from human or user reports. Human moderators play a critical role in confirming AI flags, particularly for context-dependent content where algorithmic precision may falter, and in training models through iterative feedback loops. This dual process addresses the platform's volume of over 500 hours of uploads per minute, prioritizing severe violations like material via technologies that match known illegal content hashes against uploads. Reviewers, numbering in the thousands and often multilingual to cover global content, operate from guidelines emphasizing empirical harm indicators over subjective interpretations, though outsourced moderation has faced criticism for inconsistent application due to cultural variances. Enforcement outcomes include video removals, channel strikes, suspensions, and demonetization, with appeals routed to reviewers for re-evaluation; in 2024, child safety violations constituted 53.8% of removals, underscoring prioritization algorithms that escalate high-risk content. Instances of over-reliance on , such as in when increased AI usage during reduced staffing doubled erroneous takedowns, prompted YouTube to reassign more moderators to mitigate false positives and refine classifiers. Quarterly transparency reports detail these metrics, revealing that while enables proactive removal before views accrue, oversight ensures accountability, though critics argue persistent gaps in detecting evolving threats like deepfakes expose limitations in model generalization.

Algorithmic biases and moderation failures

YouTube's recommendation algorithm has been found to exhibit political biases, particularly , where it disproportionately pulls users away from far-right content compared to far-left extremes, effectively recommending more centrist or left-leaning material. A 2023 study analyzing over 1.8 million videos determined that the algorithm favors ideologically congenial content for partisan users, with this effect intensifying further along recommendation chains, potentially reinforcing chambers rather than broadening exposure. Empirical audits from 2020 to 2023, including those examining recommendation drifts, indicate that while the system does not aggressively promote as once claimed, it systematically deprioritizes certain viewpoints, such as those diverging from mainstream progressive narratives on topics like or historical events. These biases arise from models trained on user engagement data, which prioritize watch time and clicks, inadvertently amplifying sensational or aligned content while suppressing alternatives, as evidenced by probabilistic analyses of recommendation networks showing skewed node influence distributions. Critics, including conservative creators, have alleged shadowbanning—reduced visibility without notification—targeting right-leaning channels, though YouTube officially frames this as "borderline content" reduction using AI models to limit spread of low- or policy-violating videos. for ideological shadowbanning remains largely anecdotal, with creators reporting sudden view drops uncorrelated to content , but platform from July 2022 onward attributes such throttling to automated reviews hundreds of thousands of hours daily. Academic reviews note that while algorithmic lacks transparency, user-generated accountability efforts by creators highlight persistent disparities in promotion, potentially stemming from training reflecting institutional biases in content labeling. Moderation failures have repeatedly exposed gaps in YouTube's , particularly in protecting vulnerable users from harmful content. In 2017, public reports of videos received responses in only a fraction of cases, prompting to hire 10,000 additional amid scandals involving exploitative material evading filters. By February 2019, advertisers including and boycotted the platform after their ads appeared alongside children's videos inundated with pedophilic comments, revealing algorithmic recommendations funneling viewers—including children as young as 9—to gun or extremist content. A 2024 incident saw a remain online for hours before removal, with the channel deleted only after manual flagging, underscoring delays in automated detection systems. Even dedicated apps like have faltered, with studies and reports from 2023–2025 documenting persistent infiltration of violent, sexually explicit, or predatory videos despite , as algorithms fail to isolate PG-rated ecosystems effectively. During the , reliance on AI amid led to increased errors in flagging or abuse content, with platforms like YouTube warning of higher mistake rates in automated moderation. These lapses, often critiqued in outlets with potential left-leaning institutional ties, reflect causal shortcomings in scaling human oversight against exponential content growth, where first-line AI filters prioritize volume over precision, allowing harmful material to accrue views before intervention.

Controversies

Privacy and data handling issues

YouTube collects extensive user , including watch history, search queries, location information, device details, and demographic inferences, to personalize recommendations and advertisements. This data aggregation occurs through mechanisms such as (e.g., the 'PREF' cookie for playback preferences) and embedded tracking technologies that monitor interactions across sessions. In 2019, the U.S. fined and YouTube $170 million for violations of the (COPPA), stemming from the platform's failure to obtain parental consent before collecting personal information from children under 13 on videos directed at them, including data used for . This settlement required YouTube to implement new safeguards, such as age-gating content and disabling personalized ads on child-directed videos, highlighting systemic issues in distinguishing and protecting minor users' data. Under the European Union's (GDPR), French regulator CNIL imposed a €50 million fine on in 2019 for inadequate transparency and invalid mechanisms in personalized , practices integral to YouTube's operations. Subsequently, in 2021, CNIL levied an additional €90 million fine specifically on YouTube for making refusal more difficult than acceptance, violating user requirements for in . These penalties underscore repeated deficiencies in obtaining explicit, granular for data handling, particularly for non-essential tracking. In January 2019, the None of Your Business (NOYB) organization filed strategic complaints against YouTube for failing to provide full access to users' personal data under GDPR Article 15. On August 7, 2025, after a 5.5-year process, the Austrian Data Protection Authority (DSB) ruled in favor of the complainant, ordering Google/YouTube to disclose all personal data processed about the user and identifying structural violations in data access compliance. Data sharing with advertisers involves anonymized profiles derived from user behavior, enabling cross-site tracking despite privacy controls like incognito mode or ad opt-outs, which do not fully prevent inference-based targeting. A 2023 report revealed that YouTube's ad practices on children's channels facilitated third-party tracking across the web, potentially exposing minors to persistent profiling beyond the platform. In August 2020, a third-party database breach exposed profile for approximately 235 million YouTube user accounts, including usernames, addresses, and IP details, aggregated from public sources but highlighting vulnerabilities in ecosystems linked to the platform. While not a direct internal breach, it demonstrated risks from YouTube's footprint in external compilations used by marketers.

Censorship and content suppression claims

Numerous creators, particularly those with conservative viewpoints, have accused YouTube of engaging in and content suppression by restricting, demonetizing, or removing videos that challenge prevailing narratives on topics such as , , and elections. In 2017, Prager University filed a against YouTube and , alleging that over 50 of its educational videos on subjects like , gun rights, and were unfairly demonetized or age-restricted due to ideological bias, claiming this violated laws and the First Amendment. The Ninth Circuit Court of Appeals dismissed the case in 2020, ruling that YouTube, as a private platform, is protected under of the and not obligated to host content as a public forum. High-profile suspensions have fueled these claims, including the indefinite suspension of former President Donald Trump's channel on January 12, 2021, following the January 6 Capitol events, for alleged violations of policies against inciting violence after he posted a video disputing the election results. Trump sued YouTube in October 2021, asserting wrongful censorship, leading to a $24.5 million settlement in September 2025 without admission of liability. Similarly, YouTube removed over 1 million videos containing COVID-19 misinformation between February 2020 and August 2021, targeting claims like vaccines causing infertility or false cures, which critics argued suppressed legitimate debate on public health policies. Allegations of —reducing visibility without notification—persist, with creators reporting sudden drops in views and search rankings for politically sensitive content, though YouTube denies systematic practices and attributes changes to algorithmic adjustments. In , agencies investigated YouTube staff in 2024 for allegedly shadow banning pro-government content, highlighting potential targeted suppression. Recent policy shifts include YouTube's September 2025 announcement to reinstate accounts banned for pandemic or election-related content under Biden administration pressure, and loosening rules in June 2025 to allow some previously prohibited , amid Republican scrutiny. Courts have consistently rejected First Amendment challenges, affirming platforms' editorial discretion, yet settlements and policy reversals suggest external pressures influenced enforcement.

Demonetization and advertiser conflicts

YouTube's demonetization process involves disabling ad for individual videos or entire channels that violate its advertiser-friendly content guidelines, which prohibit elements such as excessive , , themes, promotion of or drugs, and controversial or sensitive issues including tragedies or conflicts. These guidelines, enforced through a of reviewers and algorithms, aim to ensure brand safety for advertisers by limiting ads on content deemed unsuitable, though enforcement has often been criticized for vagueness and inconsistency. The most significant advertiser conflicts erupted in early 2017, known as the "Adpocalypse," when major brands discovered their ads appearing alongside extremist, , or terrorist-related videos, prompting widespread boycotts. Companies including , , , , Verizon, and suspended advertising on YouTube and Google platforms, citing risks to brand reputation from adjacency to objectionable content. This backlash, fueled by revelations that groups like had monetized videos on the platform, led YouTube to overhaul its ad placement systems and introduce stricter automated flagging for demonetization. In response, YouTube expanded its policies in April 2017 to demonetize content with even mild or sensitive topics, affecting a broad range of creators beyond those producing material. Creators reported revenue drops of up to 90% in some cases, with gaming or educational channels unexpectedly flagged due to algorithmic overreach or contextual misinterpretations, such as discussions of historical events. Later that year, another wave of boycotts followed scandals involving ads on videos with child exploitation comments or themes, drawing in brands like , , Mars, and . These events highlighted ongoing tensions, as advertiser demands for "safe" environments prioritized risk aversion over content diversity, resulting in demonetization of videos on topics like politics, mental health, or swearing in non-offensive contexts. While some brands like Procter & Gamble resumed advertising by 2018 after YouTube implemented better controls, creators continued to face unpredictable income loss, prompting diversification to platforms like Patreon or direct sponsorships. By 2023, policy updates focused on repetitive or mass-produced content rather than advertiser boycotts, but the 2017 precedents underscored how platform revenue dependency amplifies conflicts between creator expression and corporate advertiser sensitivities.

Free speech and ideological bias allegations

Allegations of ideological bias and free speech restrictions on YouTube have primarily emanated from conservative commentators and organizations, who contend that the platform systematically demonetizes, deranks, or removes right-leaning content while permitting left-leaning equivalents to proliferate. These claims intensified around 2016-2017 amid rising , with critics arguing that YouTube's moderation disproportionately targets viewpoints skeptical of mainstream narratives on topics like , , and election integrity. For instance, in 2019, comedian Steven Crowder's channel faced demonetization following a public dispute with Vox journalist over alleged harassment, though YouTube initially deemed the content non-violative of policies before restricting ad revenue. A prominent case involved Prager University, a conservative advocacy group, which sued (YouTube's parent) in October 2017, alleging censorship of 37 videos on subjects including , gun rights, and by restricting them to age-inappropriate audiences, thereby limiting visibility. The U.S. of Appeals for the Ninth Circuit dismissed the claims in February 2020, ruling YouTube constitutes a private forum not bound by the First Amendment and protected under of the , which shields platforms from liability for moderation. PragerU's subsequent state court appeal in was affirmed dismissed in December 2022 on similar grounds, underscoring judicial consensus that platforms retain editorial discretion. Empirical analyses of YouTube's recommendation reveal mixed evidence on . A 2023 study published in PNAS found the system promotes ideologically congenial content to partisan users, potentially reinforcing echo chambers, but with greater in trails for right-leaning viewers. Conversely, a 2023 indicated left-leaning in U.S. recommendations, attributing it not solely to aversion but to broader curatorial preferences. A 2021 New York University report, cited in outlets like , asserted no systemic anti-conservative censorship and claimed algorithms amplify right-wing voices, though such findings from academia—often aligned with progressive institutions—have faced for underweighting anecdotal demonetization patterns among conservative creators. YouTube has defended its practices as neutral enforcement of community guidelines against , , and , rather than viewpoint discrimination, emphasizing its status as a private entity without constitutional free speech obligations. Recent developments, including Google's September 2025 admission of suppressing content at federal request during the Biden administration and pledges to reinstate thousands of politically banned accounts, have fueled perceptions of prior overreach. In October 2025, YouTube launched a "second chance" program for creators previously banned for or election-related , alongside policy relaxations encouraging moderators to retain borderline content, prompting conservative doubt over genuine free speech reforms amid ongoing algorithmic opacity.

Societal Impact

Cultural and media democratization effects

YouTube has fundamentally reduced entry barriers for media production by enabling individuals to upload videos using consumer-grade smartphones and internet connections, bypassing traditional gatekeepers such as studios, networks, and publishers that historically required significant capital and connections. This shift, initiated after the platform's launch, has allowed over 500 hours of new content to be uploaded every minute as of the mid-2010s, scaling to billions of hours viewed annually by diverse creators worldwide. Empirical data indicate that such accessibility has empowered non-professional producers to generate content in categories ranging from tutorials and vlogs to music and commentary, fostering innovation through distributed communities without reliance on centralized approval processes. Independent creators have leveraged this openness to build audiences and revenue streams competitive with established media, with top YouTubers in 2025 increasingly forgoing Hollywood deals in favor of direct-to-audience models that offer greater creative control and earnings potential. Advertising revenue from platforms like YouTube is forecasted to surpass traditional media companies for the first time in 2025, driven by creator-generated content on YouTube, , and , reflecting a causal reallocation of economic value from legacy broadcasters to decentralized producers. YouTube's revenue-sharing model, which allocates approximately 55% of ad earnings to creators, further incentivizes this transition by tying compensation directly to viewer engagement rather than upfront production deals. Culturally, YouTube's has accelerated the mainstreaming of niche and expressions, launching careers for musicians, comedians, and influencers who previously lacked distribution channels, while amplifying global trends like viral challenges and DIY movements. The platform's influence extends to everyday language, with "YouTube" used informally as a verb meaning to watch, search for, or upload content on the platform, the past tense of which is "youtubed" or "YouTubed". The platform's dominance in viewing habits—capturing 10.8% of total U.S. television usage in July 2025—demonstrates how has eroded traditional media's monopoly on cultural gatekeeping, enabling broader participation in shaping public discourse and entertainment. However, this yields uneven outcomes, as statistical analyses show only about 1 in 57 YouTube creators reaching 10,000 subscribers, underscoring that while access is widespread, algorithmic visibility and sustained engagement determine scalable success.

Political influence and polarization dynamics

YouTube's recommendation algorithm prioritizes content that maximizes user engagement, often favoring videos with high emotional arousal, which can include politically charged material over neutral reporting. Empirical analyses indicate that while the system recommends ideologically congenial videos to partisan users—deepening exposure within existing preference trails—it does not systematically drive most viewers into extremist "rabbit holes." For instance, a 2022 Brookings Institution study of real-user recommendations found limited evidence of the algorithm pushing users toward ideological echo chambers or radical content for the vast majority, though it does amplify similar viewpoints, potentially entrenching divides among already polarized audiences. Similarly, a 2023 PNAS audit revealed that congenial recommendations increase along recommendation chains for both left- and right-leaning users, but short-term exposure to such "filter bubbles" yields negligible shifts in attitudes or beliefs. Critiques of highlight asymmetries in content promotion, with some suggesting a left-leaning in deradicalization efforts, pulling users more aggressively away from far-right material than from progressive extremes. A 2023 study analyzing U.S. recommendations found the system steers users from partisan fringes overall, but with greater suppression of right-wing content, potentially exacerbating perceptions of platform among conservative creators and viewers. Conversely, other examinations, including a 2024 analysis, observed patterns of unsolicited recommendations for right-leaning and religious videos to ideologically diverse users, indicating algorithmic tendencies toward content with broad appeal in those domains rather than uniform ideological enforcement. These dynamics arise from engagement metrics—outrage-inducing political videos often generate higher watch times and interactions than balanced analyses—yet in comments on polarizing news videos correlates with , as measured by elevated "Toxicity Polarization Scores" in partisan threads. In electoral contexts, YouTube facilitates direct mobilization but shows mixed causal impacts on outcomes. During the 2016 U.S. presidential campaign, viral political videos amassed billions of views, yet platform-specific empirical data on vote shifts remains sparse compared to Twitter studies; one analysis of campaign effects in the "YouTube election" era (circa 2008) demonstrated that exposure to candidate videos influenced evaluations and turnout intentions, particularly among younger demographics. Broader surveys reveal that 25% of U.S. adults source political news from YouTube, with partisan viewers exhibiting heightened policy polarization, as seen in a 2023 Taiwan study where habitual YouTube news consumption among pro-independence users intensified anti-China sentiments and pro-U.S. preferences. Recent platform adjustments, such as deprioritizing political content in YouTube Shorts feeds since 2023, aim to mitigate polarization by favoring entertainment, reducing incidental exposure to divisive topics. Overall, while YouTube amplifies political voices outside legacy media—enabling figures like independent commentators to rival traditional outlets—its causal role in deepening societal rifts appears constrained by user predispositions, with algorithms reinforcing rather than originating polarization.

Educational benefits versus misinformation risks

YouTube hosts extensive educational content, including lectures, tutorials, and explanatory videos from creators such as and university channels, which empirical studies indicate can enhance learning outcomes. A 2022 study analyzing presentations, including YouTube videos, found they contributed to improved student performance in online settings, particularly during shifts to remote education. Similarly, on database courses demonstrated that supplementary YouTube videos significantly boosted students' understanding, , and retention of concepts, with participants reporting higher comprehension compared to traditional methods alone. These benefits stem from the platform's accessibility, allowing self-paced learning and visual aids that align with cognitive principles of instruction. However, YouTube's recommendation algorithm prioritizes content maximizing watch time and engagement, often favoring sensationalist videos over purely educational ones, which can expose users to misinformation. A 2019 analysis of creator perceptions revealed that the algorithm incentivizes sensationalism to boost views, potentially compromising content quality as producers adapt to visibility pressures. Fact-checkers have identified YouTube as a primary vector for disinformation worldwide, with videos on topics like COVID-19 containing false claims about treatments and origins that garnered millions of views before removal. In user-generated health content, sensationalist videos achieved 30% higher engagement rates but included misinformation in 38% of cases, underscoring how algorithmic amplification correlates with lower factual accuracy. The tension arises from uneven content distribution: while educational videos support targeted learning in controlled environments like classrooms, passive browsing often funnels users toward escalating via successive recommendations. A of YouTube's ecosystem showed that exposure to initial misleading videos, such as on , led to chains of similar low-quality content, amplifying risks for unvetted viewers.

Mitigation efforts, including authoritative source prioritization for children's content, have been implemented, but suggests persistent vulnerabilities, particularly for vulnerable demographics like high school students who may lack discernment tools. Overall, benefits accrue to deliberate users selecting high-quality channels, whereas risks dominate for algorithm-driven discovery, where engagement metrics incentivize distortion over depth.
