For their Showrunnners Issue, The Hollywood Reporter interviewed “Family Guy”‘s Seth MacFarlane and found that he wouldn’t be surprised if “Family Guy” went off the air. In fact, he’d almost welcome it.

“Part of me thinks that ‘Family Guy’ should have already ended,” he said. “I think seven seasons is about the right lifespan for a TV series. I talk to fans and in a way I’m kind of secretly hoping for them to say we’re done with it. There are plenty of people who say the show is kind of over the hill…but still the vast majority go pale in the face when I mention the possibility.”

One has to wonder what would happen if “Family Guy” went off the air after Fox has basically built an entire lineup around it. I’m sure Fox wouldn’t be too sad since they’d still have “American Dad” and “The Cleveland Show,” but the original show that started everything would be missed, for sure.

The tenth season of ‘Family Guy’ premiered last month, and his version of ‘The Flintstones’ is due to be on television sometime in 2013. You can read more about the interview, including his ideas about how to update “The Flintstones” without making it ludicrous, here.
