Cartoons Cartoons!!

Am i the only one that finds it funny that Bugs Bunny and Daffy Duck and those guys were crazy wacky bonk you on the head with a frying pan and run kinda cartoons, and pretty much ment for kids. And when you watch the cartoons that were made recently, they are all political or just simply made for adults. I mean you got WarnerBrothers toons, then you have like the Simpsons, Southpark, and the Adult Swim collection. Its kinda like when we were growing up cartoons were one way and instead of staying that way for the next generation they just kinda evolved with us. Anyone that has watched an episode of the Adult Swim has to have noticed that there is no way that any of those jokes are ment for kids. I mean i know there are still cartoons out there for kids, (pokemon and digimon, chimpokemon) but it seems like when i was growing up there weren't any cartoons for adults. I wonder what changed and what made people start doing adult cartoons... just wondering.
