The 10 Most-Watched TV Series Finales Ever

Over the past several years, television audiences have said goodbye to some of the most acclaimed television series of all time, from Mad Men to Breaking Bad. And while their finales have made a lot of headlines—sometimes for being divisive—no series yet has managed to match the ratings bonanza that came with the final episode of M*A*S*H.

More than 40 years after the series went off the air, M*A*S*H’s final episode still holds the record for the most watched television finale of all time. How long will it remain there? Only time will tell—but it certainly has already proven its staying power. In the meantime, these are the 10 most watched television series finales of all time. 

1. M*A*S*H // 1983

Viewers: 105.9 million

In 1983, 105.9 million viewers watched the Alan Alda-directed “Goodbye, Farewell and Amen” episode of M*A*S*H, which was not only the most-watched series finale ever, but the most-watched television event ever—until 2010, when the Super Bowl topped it with 106 million viewers. (In the years since, the Super Bowl has continued to be a ratings behemoth, regularly outdoing itself with each passing year.)

2. Cheers // 1993

Viewers: 80.4 million

After 11 seasons, Cheers decided it was closing time. The final episode, “One for the Road” (which aired in two parts) featured the return of Shelley Long’s Diane Chambers—and a whopping 80.4 million viewers.

3. The Fugitive // 1967

Viewers: 78 million

Andrew Davis’s 1993 film version of The Fugitive may have won an Oscar (for Tommy Lee Jones, as Best Supporting Actor), but its original TV version has some major accolades as well. Across the country, 78 million people tuned in to watch part two of the finale and see what would happen to Richard Kimble.

4. Seinfeld // 1998

Viewers: 76.3 million

One could safely estimate that at least half of the 76.3 million viewers who tuned in for Seinfeld’s finale were sorely disappointed with what they saw. One critic deemed it a big “So long, suckers!” farewell to the audience who had made the show about nothing such a big hit.

5. Friends // 2004

Viewers: 52.5 million
