Google

Google LLC (/ˈɡuː.ɡəl/ ^ⓘ, GOO-gəl) is an American multinational technology corporation focused on information technology, online advertising, search engine technology, email, cloud computing, software, quantum computing, e-commerce, consumer electronics, and artificial intelligence (AI). It has been referred to as "the most powerful company in the world" by the BBC, and is one of the world's most valuable brands. Google's parent company, Alphabet Inc., is considered part of the Big Tech group, alongside Nvidia, Microsoft, Apple, Amazon, and Meta.

Google was founded on September 4, 1998, by American computer scientists Larry Page and Sergey Brin. Together, they own about 14% of its publicly listed shares and control 56% of its stockholder voting power through super-voting stock. The company went public via an initial public offering (IPO) in 2004. In 2015, Google was reorganized as a wholly owned subsidiary of Alphabet Inc. Google is Alphabet's largest subsidiary and is a holding company for Alphabet's internet properties and interests. Sundar Pichai was appointed CEO of Google on October 24, 2015, replacing Larry Page, who became the CEO of Alphabet. On December 3, 2019, Pichai also became the CEO of Alphabet Inc..

After the success of its original service, Google Search (often known simply as "Google"), the company has rapidly grown to offer a multitude of products and services. These products address a wide range of use cases, including email (Gmail), navigation and mapping (Waze, Maps, and Earth), cloud computing (Cloud), web navigation (Chrome), video sharing (YouTube), productivity (Workspace), operating systems (Android and ChromeOS), cloud storage (Drive), language translation (Translate), photo storage (Photos), videotelephony (Meet), smart home (Nest), smartphones (Pixel), wearable technology (Pixel Watch and Fitbit), music streaming (YouTube Music), video on demand (YouTube TV), AI (Google Assistant and Gemini), machine learning APIs (TensorFlow), AI chips (TPU), and more. Many of these products and services are dominant in their respective industries, as is Google Search. Discontinued Google products include gaming (Stadia), Glass, Google+, Reader, Play Music, Nexus, Hangouts, and Inbox by Gmail. Google's other ventures outside of internet services and consumer electronics include quantum computing (Willow), self-driving cars (Waymo), smart cities (Sidewalk Labs), and transformer models (Google DeepMind).

Google Search and YouTube are the two most-visited websites worldwide, followed by Facebook, Instagram, and ChatGPT. Google is the largest provider of search engines, mapping and navigation applications, email services, office suites, online video platforms, photo and cloud storage, mobile operating systems, web browsers, machine learning frameworks, and AI virtual assistants in the world as measured by market share. On the list of most valuable brands, Google is ranked second by Forbes as of January 2022, and is fourth by Interbrand as of February 2022. The company has received significant criticism involving issues such as privacy concerns, tax avoidance, censorship, search neutrality, antitrust, and abuse of its monopoly position.

Google began in January 1996 as a research project by Larry Page and Sergey Brin while they were both PhD students at Stanford University in California, United States. The project initially involved an unofficial "third founder", Scott Hassan, the original lead programmer who wrote much of the code for the original Google Search engine, but he left before Google was officially founded as a company; Hassan went on to pursue a career in robotics and founded the company Willow Garage in 2006.

While conventional search engines ranked results by counting how many times the search terms appeared on the page, they theorized about a better system that analyzed the relationships among websites. They called this algorithm PageRank; it determined a website's relevance by the number of pages, and the importance of those pages that linked back to the original site. Page told his ideas to Hassan, who began writing the code to implement Page's ideas. Page and Brin would also use their friend Susan Wojcicki's garage as their office when the search engine was set up in 1998.

Page and Brin originally nicknamed the new search engine "BackRub" because the system checked backlinks to estimate the importance of a site. Hassan, as well as Alan Steremberg were cited by Page and Brin as being critical to the development of Google. Rajeev Motwani and Terry Winograd later co-authored with Page and Brin the first paper about the project, describing PageRank and the initial prototype of the Google search engine, published in 1998. Héctor García-Molina and Jeffrey Ullman were also cited as contributors to the project. PageRank was influenced by a similar page-ranking and site-scoring algorithm earlier used for RankDex, developed by Robin Li in 1996, with Page's PageRank patent including a citation to Li's earlier RankDex patent; Li later went on to create the Chinese search engine Baidu.

Eventually, they changed the name to Google; the name of the search engine was a misspelling of the word googol, a very large number written 10¹⁰⁰ (1 followed by 100 zeros), picked to signify that the search engine was intended to provide large quantities of information. Google was initially funded by an August 1998 investment of $100,000 from Andy Bechtolsheim, co-founder of Sun Microsystems. This initial investment served as a motivation to incorporate the company to be able to use the funds. Page and Brin initially approached David Cheriton for advice because he had a nearby office in Stanford, and they knew he had startup experience, having recently sold the company he co-founded, Granite Systems, to Cisco for $220 million. David arranged a meeting with Page and Brin and his Granite co-founder Andy Bechtolsheim. The meeting was set for 8 a.m. at the front porch of David's home in Palo Alto and it had to be brief because Andy had another meeting at Cisco, where he now worked after the acquisition, at 9 a.m. Andy briefly tested a demo of the website, liked what he saw, and then went back to his car to grab the check. David Cheriton later also joined in with a $250,000 investment.
