I noticed that each decade of cartoons had a different fad the networks kept trying to copy.
In the 70's, when Scooby Doo became popular, networks tried to make a whole bunch of teen mystery solving cartoons. Otherwise known as "Meddling Kids!" There was Goober and the Ghost Chasers, Clue Club, Jabberjaw, Fangface, The Phunky Phantom, The Amazing Chan and the Chan Clan, Josie and the Pussycats, Rickety Rocket, and Speed Buggy.
The 80's were about action figures like G.I. Joe, He-man, and Thundercats. Also cartoons about sitcom stars like Gary Coleman, Punky Brewster, The Dukes, Mork and Mindy, Laverne and Shirley, and the Fonz.
The 90's allowed cartoons to be zany and off the wall like Ren and Stimpy and Animaniacs. Plus after the popularity of the Ninja Turtles, they started making cartoons about human-like animal warriors like Biker Mice From Mars, Street Sharks, and Road Rovers.
And in the 00's, after the success of Pokemon. Monster collecting shows became the new thing like Digimon, Yu-Gi-Oh, Duel Masters, Dinosaur King, Magi-Nation, and the upcoming new series Huntik.
I just wonder what fad the 10's will bring?
