Here are the 20 most-watched episodes of TV ever, ranked
According to Nielsen 's measurements of the top network telecasts of all time, the top 20 most-watched TV episodes ever all date back at least a decade. (The "Seinfeld" finale episode in 1998, which had a very mixed reaction, was the most recent episode to crack the top 100.)
Decades-old miniseries like "Roots" and "The Thorn Birds" and finale episodes of the most popular shows in TV history dominate the list.We compiled the data from Nielsen on the most-watched broadcasts ever to create this list of the top episodes of TV.
Note: We've excluded from the list all live broadcasts, including Super Bowls and award shows, as well as movies broadcasted on TV - all of which appear prominently in Nielsen's top 100.
