Sunday will be the 700th episode of “The Simpsons.”
Wow, 700 – and counting, since Fox picked up the contract for two more years.
It’s already the longest-running scripted prime time show in American TV history, and the reasoning is simple.
Family-based sitcoms reach an apex of popularity and then the kids age, whether they are the Bradys, the Keatons, the Connors or the Cleavers.
Cartoon characters don’t age, otherwise fourth-grader Bart would be about 42 years old these days.
