[9][10] Watson's began working at Alex Jones' website InfoWars in 2002[11] where he was described as a rumour monger for fake news stories like Pizzagate.

[citation needed] Since 2011, Watson has hosted his own YouTube channel, prisonplanetlive, on which he expresses his views on topics such as contemporary society, politics, and modern liberalism in an often mocking manner.

In a 2016 interview for a student newspaper in Sheffield, UK, Watson said he grew up on a council estate with few financial resources, and that by 18, he was teetotal and exercising three hours per day.

According to The Daily Beast, "the Watson family would live in a series of similar communities that run along the leafy northwest suburbs of Sheffield, separating the city from the picturesque Peak District National Park" over the next twenty years.

According to Watson, he was initially invited to contribute by Alex Jones in 2002, and rapidly gained substantial compensation for his work on InfoWars, as stated by the former spouse of the site's founder.

[13] Watson has been described as a member of "the new far-right" by The New York Times, which wrote in August 2017 that his "videos are straightforward nativist polemics, with a particular focus on Europe" and convey his opposition to modernist architecture and modern art.

[27][3][28] In February 2017, Watson tweeted an offer to pay for a journalist to visit Sweden and stay in the "crime ridden migrant suburbs" of Malmö, if they think it would be safe.

[32] At a November 2018 White House press briefing, persistent questioning of Trump led an intern to attempt to take a microphone from the hand of CNN's Jim Acosta.

[37][38] White House Press Secretary Sarah Huckabee Sanders pointed to the video that Watson posted as clearly documenting Acosta's "inappropriate behaviour".

[40] On 2 May 2019, Watson and several other people considered to be extremists, including Nation of Islam leader Louis Farrakhan, Jones, and right-wing commentator Milo Yiannopoulos, were permanently banned from Facebook, which called them "dangerous".

"[42] Watson tweeted that he had broken "none of their rules" and complained of "an authoritarian society controlled by a handful of Silicon Valley giants" in which "all dissent must be purged.

[47] In 2022, Watson criticised French president Emmanuel Macron and France's African migrant communities, following the murder of a Jewish man in Paris.

[51] In August 2017, he said that YouTube had blocked monetisation on all his videos about Islam as part of the website's policies dealing with hate speech, and on other subjects including modern art.

In response, Joe Mulhall of Hope not Hate said that while Watson was careful to follow social media platform moderation policy, it was not surprising that he would express such views in private.
