10 Longest-Running Scripted Primetime TV Shows

It’ll be a long time before The Simpsons is dethroned as the longest-running scripted primetime series in the history of American television. Fox has renewed the animated comedy for two more seasons, meaning TV viewers won’t have to move out of Springfield until 2025 at the earliest.

The two-season renewal also means that The Simpsons will reach 800 episodes. “Eight hundred episodes — not even The Simpsons could have predicted this,” executive producer Matt Selman told Entertainment Weekly in a reference to the show’s many prescient storylines.

In honor of The Simpsons’ latest feat, we’re counting down the rest of American primetime television’s longest-running scripted series. Here’s the top 10, as ranked by season count, with ties broken by episode tally.
