The Simpsons will cross the 500 episode mark with a 23rd season at Fox, which will bring the number of episodes of the animated series to 515. “Like many 22-year-olds, The Simpsons is extremely happy remaining at home, on Fox, and hopes it doesn’t have to go out into the real world for many years to come,” said The Simpsons executive producer Al Jean. In addition to running for 22 years, The Simpsons also spawned an animated feature, which will have its broadcast premiere on Fox on Thanksgiving night.
