Cartoons have gone to hell. The only good one still on today is Spongebob. All the other good shows, which were on Cartoon Network, have all faded away and died. OK, so maybe that doesn't really have anything to do with nick, but it has something to do with the Media, which contains Nickelodeon. And, just for you, here is my list of good shows that got wiped off. In no particular order:
1# Thundercats
2# Invader ZIM
3# Dexter's Laboratory
The only ones I can think of.
