Nick was awesome in the 90s and early '00s, IMO....the 90s had classics like Doug and Rugrats and then the early 00's had stuff like Spongebob, Fairly Oddparents, and Jimmy Neutron, HOWEVER ever since 2004-ish the network has gone to crap. Mr. Meaty bombed (it's ratings are terrible, as well), and besides Spongebob, their shows all stink! Disney and TeleToon are totally owning it right now IMO...however, Nick's current live action shows are quite good. Well they were. Just Jordan and The Naked Brothers Band or whatever suck!
present-day Nick isn't as bad as present-day Cartoon Network (or "CN"), though.
