History

Historical Context

After Fox debuted The Simpsons in December 1989, the show became the network’s first top-30 hit in the 1989-90 season and, when it aired opposite The Cosby Show in summer 1990, drew an estimated 33.6 million viewers. Its success revived prime-time animation, prompting a 1990s boom that included Adult Swim’s 2001 launch by Sam Register and Warner Bros. Animation’s 2008 expansion of creator-driven series.
