December 17, 1989 –
Simpsons Roasting on an Open Fire, also known as The Simpsons Christmas Special, the first full-length episode of The Simpsons, premiered on this date.
This special was not originally intended to be The Simpsons pilot. Production problems, particularly with the first produced episode, The Simpsons: Some Enchanted Evening, saw the show delayed from its planned October debut until late December, thus dictating that this Christmas-themed episode, the eighth one produced, was the first to be broadcast. (Some Enchanted Evening was eventually broadcast as the last episode in the first season).
