way was this show cancled?

Well, it was actually cancelled because Nickelodeon didn't want any blood in the show. When they put bloody GIR in the show, it ruined everything. They also weren't getting enough views...:( But Johnen Vasquez said that the blood was actually pizza sauce. Of course, that wasn't true. But anyways, they weren't getting enough views.

The guy who made the show quit. He left unfineshed shows. The guy who made the show actually was a comic book writer, and it had gore and swearing in the books so nickolodein changed the worrds. The ratings were going down.

Because in the episode dark harvest zim was taking organs from kids and the creator quit

It was canceled because a picture of GIR got leaked onto the internet and they thought it was from the show, so they canceled it. Even though it was just GIR covered in Pizza Sauce but was not in the actual show. I would know I own them all. The Picture of GIR covered in Pizza Sauce was called "Bloody GIR". I want it back on T.V. Here is the picture. You can actually see that he is covered in Pizza Sauce. Blood doesn't hang in strings

The picture of "Bloody Gir", got me thinking. Never believe what people say on the internet. Its stupid how Nickolodeon believed this! I really hate that they canceled the show. :(

it got cancelled becuz a director hid bloody gir in the show thts why

In one episode, the creator slipped in a scene of G.I.R. covered in pizza sauce. The creator tried to explain that it wasn't blood, but Nick wouldn't listen. They cancelled the show.

Nick kept switching around it's schedule, so not alot of people could figure out what time it came on. so it got low ratings.

Well Nick thinks that the best show ever had to many things that little kids shouldn't see on it

i was because the dark havest and zim took peep's orgons and that wasn't really kid like ps and they hid bloody gir or aka pizza covered gir

Well...for starters, this question should be in the Invader Zim spot...second off, the reason fir Invader Zim got cancelled, is low ratings. For all you idiots who think its Bloody GIR, YOU'RE 100% WRONG! In fact, Nick didn't find out about BG until AFTER Invader Zim was cancelled. But lets not get into that. So IZ got cancelled to low ratings. BUT WHO CARES? ITS COMING BACK JULY 5TH!!!!!!

Do you have proof that it is?

well for me it's not cancelled any more i watch it on nicktoons
