The multi-Emmy Award winning cartoon was cancelled by bosses at America's Fox network in 2002, but revived three years later, and the series went on to become a huge success for MacFarlane, recently debuting its 10th season.
However, MacFarlane is convinced he should have ended the show on a high after the seventh series, even though devoted fans ""go pale"" at the mere mention of Family Guy finishing.
He tells The Hollywood Reporter, ""Part of me thinks that Family Guy should have already ended. I think seven seasons is about the right lifespan for a TV series. I talk to the 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.""
