CAUSE TEHY IS TURRIBL PPL!

Because of low ratings.
People way say it's about bloody g.i.r and other stuff -does'nt feel like typing to day- But in all it's about LOW RATINGS!

It was due to low ratings and an expensive budget. They had to cut the shows that had the least viewers and ZIM was one of them. Viacom was going through a lot back then. It sucks, but maybe the show still has some hope. It seems the fanbase has grown over the past 10 years, and Jhonen was talking about Nicktoons trying to 'resurrect' it. Again, they say they don't have the funding for it though. Who knows, maybe Nickelodeon will give it a second chance.

they ran out of explosive monkeys

Low Ratings. Not many people watched it back then...I did though! :D Its not about Bloody Gir you can't even see him without pausing anyway! Its back on now!! I recorded all of them!
