"The Simpsons," the longest-running scripted primetime series of all time, turns 30 years old Tuesday.
The first full-length episode of the animated series premiered on Dec. 17, 1989. It followed a series of "Simpsons" shorts that aired in previous years on another Fox comedy, the live-action "The Tracey Ullman Show."
Homer, Marge, Bart, Lisa and Maggie Simpson have noticeably evolved since the first episode, titled "Simpsons Roasting on an Open Fire," hit the air. The animation was less polished back then, and the characters sounded different -- Dan Castelanetta's Homer was much more Walter Matthau than the guy we know now. However, Bart was every bit the troublemaker then as he is now.
Over the years, however, the series ultimately shifted focus from Bart to Homer, broadening the scope of the issues it could tackle.
"Simpsons Roasting on an Open Fire" was nominated for a couple of Emmys, and the rest, as they say, is history. It has since won 34 Emmys and earned more than 80 nominations -- though none for Outstanding Comedy Series. The show has won eight People's Choice Awards, dozens of Annie Awards, a dozen Writers Guild of America awards, and other accolades of almost every type.
Starting with a voiceover guest spot from Dustin Hoffman in the second season -- who used the pseudonym Sam Etic to voice Lisa Simpson's favorite substitute teacher, Mr. Bergstrom -- "The Simpsons" has also attracted more than 700 guest stars, from Leonard Nimoy to George Harrison, Stephen Hawking, to Apollo 11 astronaut Buzz Aldrin.
In 2007, the smash hit "The Simpsons Movie" came to theaters. The yellow residents of 742 Evergreen Terrace have also starred in video games and comic books and have been made into toys, printed on T-shirts and adapted to just about every merchandise opportunity in between.
More importantly, the series has inspired generations of comic voices, and kicked the door down for mature animated series from "South Park" to "Family Guy," to "Adventure Time" and "Rick and Morty." In fact, "South Park" addressed the show's ubiquity with an episode called "Simpsons Already Did It."
"Family Guy" creator and star Seth McFarlane put it simply to ABC Audio: "'The Simpsons' is part of that exclusive club that All in the Family belongs to, of shows that utterly transformed their genre."
Last year, "The Simpsons" surpassed the classic TV Western "Gunsmoke's" long-held record of 635 episodes to become TV's longest-running scripted primetime show. And the series shows no signs of slowing down; a major addition to Disney+'s library of streaming shows, "The Simpsons" has been renewed through its 32nd season in 2021, at which point the show will surpass 700 episodes.
Disney is the parent company of ABC News and 20th Century Fox Television, which produces "The Simpsons."
