Invader Zims creator had some issues with Nick I do believe. I think he didnt want anything to do with it anymore or something..It was a good show while it lasted.

But everybody knows this is the best cartoon to come out in forever and a day. I didnt want to watch it at first because I was like "phssaw, American anime nerdz" but I fell in love with after my little sister kept watching it.
oh and
"come ooooooooooooooooooooooon"
I like some 90s cartoons too (Angry beavers and classic rugrats hokay) but the 2000s had good stuff too. Not everything in the 90s was uber wonderful, I hated Ren and Stimpy..and nearly all live action shows on nick and zomg Johnny Bravo was attrocious.
I liked the classic Fairly Odd Parents and Danny Phantom and Jimmy Nuetron...and for some strange reason Ill admit to some sort of like..for Flapjack...
The worst was Teen Titans, goddang I never understood why it was appealing..it was the reason I never wanted to see avatar.
on the same note I dont like Ben10 either.
