Bartholomew Jojo "Bart" Simpson is a fictional character from the American animated television series The Simpsons who is part of the Simpson family. Bart made his television debut in the short "Good Night" on The Tracey Ullman Show on April 19, 1987. Cartoonist Matt Groening created and designed Bart while waiting in the lobby of James L. Brooks's office. Initially called to pitch a series of shorts based on his comic strip Life in Hell, Groening instead developed a new set of characters. Unlike the other Simpson family members, who were named after Groening's relatives, Bart's name is an anagram of brat. After two years on The Tracey Ullman Show, the Simpson family received their own series, which premiered on Fox on December 17, 1989. Bart has appeared in every episode of The Simpsons except "Four Great Women and a Manicure".
