Peter Löwenbräu Griffin Sr. is a fictional character and the protagonist of the American animated sitcom Family Guy. He is voiced by the series' creator, Seth MacFarlane, and first appeared on television, along with the rest of the Griffin family, in the episode "Death Has a Shadow" on January 31, 1999. Peter was created and designed by MacFarlane himself. MacFarlane was asked to pitch a pilot to the Fox Broadcasting Company based on Larry & Steve, a short made by MacFarlane which featured a middle-aged character named Larry and an intellectual dog, Steve. For the series, Larry was renamed Peter.
MacFarlane based Peter's voice on the voices of security guards he heard while he was attending the Rhode Island School of Design.
Family Guy is an American animated sitcom created by Seth MacFarlane for the Fox Broadcasting Company. The series premiered on January 31, 1999, following Super Bowl XXXIII, with the rest of the first season airing from April 11, 1999. The show centers around the Griffins, a dysfunctional family consisting of parents Peter and Lois, their children, Meg, Chris, and Stewie, and their anthropomorphic pet dog, Brian. Set in the fictional city of Quahog, Rhode Island, the show exhibits much of its humor in the form of metafictional cutaway gags that often lampoon American culture.
