The series was originally set to debut in November of 1989 with the episode "Some Enchanted Evening" (13th and final episode of the first season), which was meant to introduce the main characters. However, during the first screening of the episode, the producers discovered that the animation was so appalling that 70% of the episode needed to be redone.

The Simpsons is the longest running prime time animated series in history; created by Matt Groening for the Fox Broadcasting Company.
