1999–2020: 20th Century Fox Television and 20th Television animation unit
The studio was established on May 19, 1999.[4] Its first project was the continued production of Family Guy for its second season, which it took over from the series' previous home at Film Roman for season one. The studio would become the home of future animated series co-created by Seth MacFarlane: American Dad! and The Cleveland Show.[5] In 2016, Fox Television Animation assumed production of Matt Groening's The Simpsons, once again taking over from Film Roman.
In March 2019, 20th Century Fox Television, 20th Television, and Fox Television Animation were acquired by The Walt Disney Company and integrated into Walt Disney Television as part of Disney Television Studios.[9] In September 2020, the company was renamed as 20th Television Animation starting with newer episodes of shows in production at the company.
In December 2020, it was announced that 20th Television Animation would be relaunched as a standalone unit from 20th Television. In March 2021, Marci Proietto was tentatively named as president of the company. 20th Television Animation focuses on producing and developing animated projects targeted at teens and adults, as opposed to their children-targeted sister studio Disney Television Animation. Under the new incarnation, 20th Television Animation would assume executive supervision of the production of all animated projects that had, up to that point, been overseen by 20th Television. This allowed series that 20th Television Animation was already producing animation for under 20th Television's watch to be brought entirely under one company, while series whose animation was produced by a third-party company would retain that relationship, with 20th Television Animation only absorbing the above-the-line production and acting as the new client for the animation contractor.[10][11]
On March 16, 2022, it was announced that the studio would collaborate with children-targeted sister studio Disney Television Animation, for the creation of young adult animated series, mini-series and movies for Disney+.[12]
