Do you think that Teen Titans Go! could beat The Simpsons as the American cartoon with more episodes?
Teen Titans Go! reached 400 episodes in 11 years. It's possible that the show could beat The Simpsons as the cartoon with more episodes?. The Simpsons has currently 771 episodes and 36 seasons and it's running since December 17, 1989, being the longest-running American animated series, but it's not a kids' show.
The longest-running kids' cartoon is SpongeBob SquarePants.
In my opinion, I don't think that Teen Titans Go! could beat The Simpsons, the show is renewed despite the low ratings.
There's some Japanese anime series with more episodes than The Simpsons: Sazae-san is running since 1969 with 8000+ episodes and it won the Guinness World Record in 2013 for being the world's longest-running animated series.
But this thread is about American cartoons, not anime.
