Golden-age Simpsons ranks number one on my list, far and beyond. Ren and Stimpy, Animaniacs (even after Pinky and the Brain got their own show), The Powerpuff Girls, Spongebob, Batman, and Dexter's Lab are also strong favorites.
Outside of A Pup Named Scooby Doo (which debuted in '88 and ended in '91), it only had straight to video movies.Cheery Lunatic said:Scooby Doo (I think new episodes came out in the '90s as well)
