CBS still has Kewlopolis on Saturday mornings. It's a block of programming aimed mostly at girls, featuring Strawberry Shortcake, Sushi Pack, Care Bears and other stuff including an oddball boys show about fighting dinosaurs, or people who turn into dinosaurs, or something like that. It has Cake, which is live action, but that's a longrunning Saturday morning tradition.
Another thing you have to realize is that it's simply a different media world today than it was years ago. About 6 or seven big corporations control most of the media, and synergy is the name of the game. So things like Disney buying out ABC and deciding it would be cheaper to reair Disney shows on ABC Saturday morning are the norm.
