The Simpsons has just made television history. Again.
Fox announced today that with the renewal of the sitcom for two more seasons, the show officially has the most episodes for a scripted series ever. As of the end of the 30th season, The Simpsons will have aired 669 episodes over the course of 27 years, usurping the current record-holder, Gunsmoke.
Gunsmoke, a Western show that aired on both radio and television, had its small-screen debut in 1955 and ran until 1975, airing a total of 635 episodes. The show tied Law & Order for longevity, with both shows sharing a record for airing 20 seasons, the most for a live-action drama.
The Simpsons also holds the record for the longest-running scripted series on television, beating out Law & Order, Gunsmoke, and other popular series like ER and Grey’s Anatomy. The show still averages 7.2 million viewers per week, according to Fox, with the series’ milestone 600th episode garnering just under 10 million live viewers.
Fox Chairman Dana Walden and CEO Gary Newman heralded the series for its longevity, calling the writers and artists that worked on the show, “the greatest collections of creative talent in the history of the medium.”
Since its inception in 1989, The Simpsons has been adapted into a comic book, video games and a feature-film. The show has also launched the career of successful writers and comedians, like late night host Conan O’Brien.
The Simpsons airs Sunday nights at 8:30 p.m. ET on Fox.
