Well this seems like an intelligent decision. Fox turned down South Park. Over time we have become well accustomed to watching corporations making what they thought was a good decision at the time, only to turn into a monstrous blunder. You only need to look at the case of Blockbuster or Excite to really see how disastrous an executives decision can turn out to be.
Back in the late 1990’s there were a few cartoon shows that were being target towards a more mature audience. While the majority of cartoons have had a focus on children, some shows had adults in mind, yet unfortunately were seen by many adults at the time as vulgar childrens shows, and a bad influence. You only need to watch a few episodes of The Simpsons, Beavis and Butt-head or King of the Hill to see that the intended audience was not children. This is where South Park enters the picture. It’s a show that is based on a group of school children who are as vulgar as they come. But school kids can’t be that bad can they? Well, back when it first aired many adults unwittingly allowed their kids watch the show, thinking a cartoon was really targeted for children, just like Disney cartoons.
