Syndication

The cable television network FXX, a sibling of 20th Television and formerly the Fox network, has exclusive cable and digital syndication rights for The Simpsons. Original contracts had previously stated that syndication rights for The Simpsons would not be sold to cable until the series conclusion, at a time when cable syndication deals were highly rare. The series has been syndicated to local broadcast stations in nearly all markets throughout the United States since September 1994.

FXX premiered The Simpsons on their network on August 21, 2014, by starting a twelve-day marathon which featured the first 552 episodes (every single episode that had already been released at the time) aired chronologically, including The Simpsons Movie, which FX Networks had already owned the rights to air. It was the longest continuous marathon in the history of television (until VH1 Classic aired a 433-hour, nineteen-day, marathon of Saturday Night Live in 2015; celebrating that program's 40th anniversary). The first day of the marathon was the highest rated broadcast day in the history of the network so far, the ratings more than tripled those of regular prime time programming for FXX. Ratings during the first six nights of the marathon grew night after night, with the network ranking within the top 5 networks in basic cable each night. In Australia, a marathon of every episode of the show (at the time) aired from December 16, 2019, to January 5, 2020, on Fox8 (a cable network operated on pay TV provider Foxtel and a corporate sibling to the American Fox network).

After Disney acquired both 20th Television and FX Networks, it was announced that The Simpsons would air on the company's Freeform channel starting October 2, 2019.
