>>97595487Yes, Cartoon Network has/had shows that do appeal to an older demographic. Adventure Time, Regular Show, Gumball, Original PPG, Dexter's Lab, Cow and Chicken, Ed Edd N Eddy, Johnny Bravo, Courage, etc.
But can you guess what all these shows have in common? They have never said swear words or gone too deep into adult content. They have an older appeal but they're definitely not on the same level as The Simpsons or Rick and Morty.
