The first season of the American animated television series The Simpsons originally aired on the Fox network between December 17, 1989, and May 13, 1990, beginning with the Christmas special "Simpsons Roasting on an Open Fire." The executive producers for the first production season were Matt Groening, James L. Brooks, and Sam Simon. The series was originally set to debut in fall 1989 with the episode "Some Enchanted Evening", (which was meant to introduce the main characters), but during the first screening of the episode, the producers discovered that the animation was so poor that 70% of the episode needed to be redone. The producers considered aborting the series if the next episode turned out as bad, but it suffered from only easily fixable problems. The producers convinced Fox to move the debut to December 17, and aired "Simpsons Roasting on an Open Fire" as the first episode of the series. The first season won one Emmy Award, and received four additional nominations. The DVD boxset was released on September 25, 2001, in Region 1 and September 24, 2001, in both Region 2 and Region 4. With a total of 13 episodes, this is the shortest season of the show to date.
