"The Simpsons" already surpassed TV Legend status back in February when it aired its 500th episode on Fox. Today, the show (or at least, the characters on the show) reach another milestone: April 19, 1987 marks 25 years since the Simpson family of Springfield first appeared on television during an episode of the "The Tracey Ullman Show."
In all, 48 video shorts featuring Homer and Bart and the rest of the yellow-skinned clan, ran on "The Tracey Ullman Show" until the cartoon family got their own show on Fox. "The Simpsons" premiered on December 17, 1989.
To mark today's anniversary, we give you Duke professor Harris Cooper, an expert on education policy who happens to also be a bit of an expert on "The Simpsons."
