Homer Jay Simpson is the protagonist of the American animated sitcom The Simpsons. He is voiced by Dan Castellaneta and first appeared, along with the rest of the Simpsons, in The Tracey Ullman Show short "Good Night" on April 19, 1987. Homer was created by the cartoonist Matt Groening while he was waiting in the lobby of producer James L. Brooks's office. Groening had been called to pitch a series of shorts based on his comic strip Life in Hell but instead created a new set of characters. He named the character after his father, Homer Groening. After appearing for three seasons on The Tracey Ullman Show, the Simpsons received their own series on Fox, which debuted on December 17, 1989.
