There are many more options for animated entertainment, and The Simpsons is now a drop in the pond. I think they hold on mostly for nostalgia reasons, as they just aren't really relevant anymore.
TV is a business. They don't do things for nostalgia, they do it for profit. The Simpsons is still on because enough people are still watching it to make it profitable. Ratings have never had much to do with quality. A lot of people like familiar, comfortable formulas that let them turn off their brains.
Hell, if there are enough people with no taste to justify giving a hack like Seth McFarlane three shows, it doesn't surprise me that The Simpsons is still hanging on. Even at its worst, it's more watchable than McFarlane's stuff -- and I'm saying this as someone who recently gave up on watching The Simpsons altogether.
I'm referring to the idea that the audience is holding on for nostalgia reasons. There are kids going off to college and they've never been alive when the Simpsons weren't on the air.
