"The Simpsons" is an American animated television sitcom created by Matt Groening for the Fox Broadcasting Company.
 It is a satirical depiction of a middle class American lifestyle epitomized by its eponymous family, which consists of Homer, Marge, Bart, Lisa, and Maggie.
 The show is set in the fictional town of Springfield, and lampoons American culture, society, and television, as well as many aspects of the human condition.
 The family was conceived by Groening shortly before a pitch for a series of animated shorts with producer James L. Brooks.
 Groening created a dysfunctional family and named the characters after members of his own family, substituting Bart for his own name.
 The shorts became a part of the Fox series "The Tracey Ullman Show" on April 19, 1987.
 After a three-season run, the sketch was developed into a half-hour prime-time show that was an early hit for Fox.
