When should have The Simpsons been cancelled?

[StokedUp]

The Simpsons is ok and it's still sometimes pulls out some good new episodes I'm not sure whether it should be cancelled though. It's still enjoyed by millions, I just can't beleive Futurama didn't do as well it it because in my opinion Futurama was the better one and has so much more potential for greater episodes due to its theme I also prefer almost every character in Futurama compared to the the Simpsons, Fry leela farnsworth and all the rest are just better than homer, marge, Bart and gang.
