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.
Homer's design has been revised several times over the course of the series. Left to right: Homer as he appeared in "Good Night" (1987), "Bathtime" (1989), and "Bart the Genius" (1990).
"I was trying to find something I was more comfortable with that had more power to it, so I had to drop the voice down. ... People will say to me, 'Boy, I'm glad they replaced the guy that was there that first season.' That was me!"—Dan Castellaneta
