TomSka

As a child, Ridgewell began making short films using his parents' video camera. Not long after YouTube was established, Ridgewell created CakeBomb, a website where he posted his video creations, including his viral animated video series asdfmovie and his friend Edd Gould's Eddsworld. Ridgewell graduated from University of Lincoln,[5] where he studied Media Production, and whilst studying he created a series of unofficial "advertisements" for the university which received millions of views.[6]

As a professional YouTuber, Ridgewell earns money from revenue on his videos on the website.[7] He also has made short films for BBC and Comedy Central. He has been discussed and interviewed in relation to this, especially when the medium of online video was in its infancy.[2][8] He has also appeared as a guest on the BBC's The One Show, and has appeared as a radio and TV guest internationally.[9]

In October 2007, Ridgewell created a secondary channel called DarkSquidge.[10] As of January 2020, the channel has over 1 million subscribers and more than 178 million views.[10] The content he uploads on this channel differs greatly from that of his main channel. While his main channel consists of sketch comedy and animations,[11] DarkSquidge shows behind the scenes footage of TomSka related projects and videos, as well as vlogging. Ridgewell also engages in social commentary on this platform, covering a range of topics such as mental health, sexual health, and body positivity. He uploaded weekly vlogs to the channel dubbed Last Week. After ending Last Week, he then made a monthly vlogging series called Last Month,[12] with a new series of videos known as #CONTENT forming the bulk of the channel's uploads.

In 2008, Ridgewell released the first installment of asdfmovie, an animated sketch comedy series featuring very short clips of minimally-detailed characters in surreal and occasionally darkly humorous situations. There have been twelve episodes as of August 2019, as well as three "deleted scene" videos, a promotional video with Marmite, and four music videos; "I Like Trains", "Mine Turtle", "Everybody Do The Flop", and "The Muffin Song".[13] The song "Beep Beep I'm a Sheep" by Canadian musician LilDeuceDeuce with vocals by Ridgewell and Gabriel Brown,[14] released alongside asdfmovie10, was featured in the dance rhythm game Just Dance 2018.[15] A book based on the asdfmovie series, titled Art is Dead: the asdf book, was written by Ridgewell, illustrated by Matt Ley, and published by Little Brown on 22 October 2015.[16] A second book titled Sam Kills Christmas, written by Ridgewell and Eddie Bowley with illustrations by Dorina Herdewijn, was released on 8 November 2018.[17][18]

In 2012, Ridgewell founded a media production company, TurboPunch Ltd., located in London. He currently works there alongside co-writer Eddie Bowley and video editor Elliot Gough.[19] Both make appearances in sketches on the main channel, but are more often featured in videos on the second channel.

Also in 2012, Ridgewell took charge of the production of Eddsworld after the show's original creator, Edd Gould, died of leukemia. He left the series in 2016, handing the show over to Edd's family. In 2013, he was featured in YouTube's first "Comedy Week".[20] He was featured on the cover of Wired UK in February 2013 as part of a feature titled "How YouTube Reinvented the Entertainment Business"[21] and was selected by YouTube as a guest host for its Geek Week series in August. The BBC announced that Ridgewell would appear as a guest presenter on the Dan and Phil Show in September 2014 on BBC Radio 1.[22][23][24]

In 2014, Ridgewell, in collaboration with video game developer Pixel Spill Studios, created the game KatataK, a side-scrolling shoot 'em up for iOS and Android devices.[25][26]

In January 2015, Ridgewell launched a new webtoon, Crash Zoom, on his TomSka channel. It is animated by Ben "Wonchop" Smallman, who also animated some of the asdfmovie episodes.[27] It features three young characters, Lucy, Ben, and Kate, in their various surreal exploits.[28]

In 2016, Ridgewell filmed several sketches with the BBC in a trial for a potential sketch show on BBC Three. These sketches were not picked up by the BBC, however, and he later posted the clips on his YouTube channel.[29]

In 2019, Ridgewell developed a card game based on asdfmovie in collaboration with Big Potato Games called Muffin Time: The Random Card Game.[30] He raised over £1,000,000 for the game on Kickstarter.[31]

Ridgewell’s twin sister, Amelia, died prenatally after their mother sustained injuries in a car accident. This is reflected in his name (Thomas meaning twin).[32]

He was raised a Jehovah's Witness, but no longer practices this faith.[33] Despite this, he has expressed a hope in a higher power.[32]

Though not primarily a musician by trade, Ridgewell has performed bass in a couple of videos, including "Guitar Warfare"[34] and "Mine Turtle" as a featured artist with LilDeuceDeuce.[35] He also performed vocals on "Mine Turtle", "Beep Beep I'm a Sheep", and sketch video "Musical Suicide".

He endorsed the Labour Party in the 2017 United Kingdom general election.[36] He also expressed his opposition to both Brexit[37] and the Conservative Party.[38]
