The family was conceived by MacFarlane after developing two animated films, "The Life of Larry" and "Larry & Steve". MacFarlane redesigned the films' protagonist, Larry, and his dog, Steve, and renamed them Peter and Brian, respectively. MacFarlane pitched a seven-minute pilot to Fox in 1998, and the show was greenlit and began production. "Family Guy"'s cancellation was announced shortly after the third season had aired in 2002, with one unaired episode eventually premiering on Adult Swim in 2003, finishing the series' original run. Favorable DVD sales and high ratings from syndicated reruns since then convinced Fox to revive the show in 2004; a fourth season would begin airing the following year on May 1, 2005.
