Hbomberguy

Harry Brewis (born 19 September 1992), better known as Hbomberguy, is a British YouTuber and Twitch streamer. Brewis produces video essays on a variety of topics such as film, television, and video games; often combining them with arguments from left-wing political and economic positions. He has created videos aimed at debunking conspiracy theories and responding to right-wing and antifeminist arguments.

Harry Brewis was born on 19 September 1992 in West Yorkshire, England. He studied English literature with a focus on creative writing at Aberystwyth University. Before focusing on his own YouTube channel full time, Brewis worked as an information technology engineer, then as an animator for The School of Life's YouTube channel.

Brewis started the Hbomberguy YouTube channel on 28 May 2006. As of June 2025, the channel has over 1.8 million subscribers. He also uploads his videos on the online streaming service Nebula.

Brewis's videos often take the format of short documentaries, with him talking directly to the camera on a particular topic interspersed with comedic sketches and gags. He consults with experts and fact-checkers for his videos to ensure their factual accuracy. Some of the most popular videos on his channel are his A Measured Response series, which features Brewis critiquing figures such as flat Earth conspiracy theorists, pickup artists, anti-vaxxers, and content creators who believe soy makes men feminine and use the term soy boy. Due to his videos debunking right-wing and alt-right ideas, Brewis has commonly been described as a part of BreadTube, an informal network of left-leaning YouTubers; however, he does not associate himself with the term. Like other YouTube channels under the BreadTube label, Brewis's political content mirrors the presentation of popular non-political content creators such as pop-culture essayists and gaming YouTubers.

Along with his political analysis and Measured Response series, Brewis has been producing long-form media reviews and video essays on a number of topics, such as television, film, internet culture and video games. In July 2020, Brewis released a video criticising the American web series RWBY. Prior to its release, Brewis attempted to upload the video and found it automatically blocked by YouTube's Content ID system. Brewis opted to extensively re-edit the video to circumvent this automated detection and hire a lawyer to review the content in order to ensure it complied with fair use prior to publication. In an essay criticising the Content ID system, the Electronic Frontier Foundation highlighted Brewis's difficulty as an example of how they believed Content ID "undermines" the intent of fair use.

In November 2022, Brewis published "ROBLOX_OOF.mp3", a video essay which documented many of the high-profile claims that Tommy Tallarico had made concerning his career, including being the creator of the sound effect at the heart of his Roblox legal dispute, his Guinness World Records, and being the first American to work on the Sonic the Hedgehog franchise, and concluded many were either exaggerations or knowingly false.

From 18 to 21 January 2019, Brewis continually livestreamed to raise money for British transgender charity organisation Mermaids. In this stream, he aimed to complete Donkey Kong 64 while finding all possible collectable items and did so in 57 hours and 48 minutes. Mermaids had been designated funding by the British National Lottery, but the funding was withheld and put under review after criticism by comedy writer and anti-transgender activist Graham Linehan and others. This inspired Brewis to stream in support of the charity.

The livestream featured many notable guests, including U.S. Representative Alexandria Ocasio-Cortez; activist and whistleblower Chelsea Manning; actress Mara Wilson; journalists Paris Lees and Owen Jones; Adam Ruins Everything creator Adam Conover; author Chuck Tingle; Matt Christman and Virgil Texas of the Chapo Trap House podcast; Donkey Kong 64 composer Grant Kirkhope; NFL athlete Chris Kluwe; game designers Rebecca Heineman, Josh Sawyer, John Romero and Scott Benson; YouTubers Natalie Wynn, Lindsay Ellis, Abigail Thorn and James Stephanie Sterling; as well as the then CEO of Mermaids, Susie Green. Colin Mochrie, Neil Gaiman, Cher, Matthew Mercer, Adam Savage, Hidetaka Suehiro and SonicFox tweeted in support of the livestream and the charity. The livestream began with a goal of US$500; it quickly passed that goal and several subsequent funding targets. In the first 24 hours, the livestream raised over $100,000. In total, over $347,000 (£265,000) was raised for the charity through the livestream, with over 659,000 people watching the stream.
