Seth MacFarlane, creator of the beloved series "Family Guy" and "American Dad," announces his retirement. The move will not immediately affect the two successful series.
Family Guy has ended its professional commitments for the 21st season, which ended its May 7 run after 20 episodes. As far as "AmericanDad," which began airing its 20th season in early March, still has enough episodes left to allow it to run for at least another three months, it has been learned.
