Judge began creating "King of the Hill" during his time making the MTV series "Beavis and Butt-Head", which he also created and voiced. After pitching the pilot to Fox, Judge was paired with Greg Daniels, an experienced writer who previously worked on "The Simpsons". The series debuted on the Fox network as a mid-season replacement in 1997, quickly becoming a success. The series' popularity led to worldwide syndication, and reruns aired on Cartoon Network's late night programming block, Adult Swim from 2009 until 2018. Reruns began airing on Comedy Central from July 24, 2018, to November 2019. The show became one of Fox's longest-running series. A total of 259 episodes aired over the course of its 13 seasons. The final episode aired on Fox on September 13, 2009. Four episodes from the final season were to have aired on Fox, but later premiered in nightly syndication from May 3 to 6, 2010.
