A while back I was talking to a guy who works at Nickelodeon.  He said the difference between Nick employees and Cartoon Network employees is that people at Cartoon Network are jerks who think they are cutting-edge.  Here is an ad from a Cartoon Network show that came out last year.

I think this show is hilarious, but I can see his point.  I think any show on a network reflects that network's philosophy on entertainment.  If anybody has other good examples of networks that have their own particular brand of entertainment, post a comment.  Include a YouTube link too, if you can find one.
