This show is so iconic it almost doesn’t need mentioning. Since “The Simpsons” first aired on FOX in 1989, the dysfunctional family has become a bastion in the TV world, bringing us some of television’s most loved characters. The show regularly parodies newer shows and other aspects of popular culture, making it an important authority on public opinion. A feature film was released in 2007 that only cemented the popularity of “The Simpsons” across many generations. With little sign of slowing down, the show finished its 24th season this year, making it the longest-running American primetime, scripted TV series.
