Nickelodeon
nickelodeon was once a good network from late 80s to early 90s with programs like you can't say that on telivison, welcome freshman, round house, are you afraid of the dark?, pete and pete, salute your shorts, and hey dude.

These shows were canceled and were replaced by copy-cat versions of some shows (roundhouse became all that)and all around started to suck...now most of the current shows are plotless, and shitty
Nickelodeon used to be awsome, and now it sucks
