The series finale of 'Friends' was the most watched TV episode of the decade.

The one in which Ross and Rachel finally made it official is the most-watched regular TV episode of the decade.

The May 6, 2004 "Friends" finale was watched by 52.5 million people, according to the Hollywood Reporter, putting it ahead of other must-see-TV moments like the "Survivor: Borneo" finale in which villain Richard Hatch won the top prize (#2 on the list with 51.7 million viewers) and the "Grey's Anatomy" post-Superbowl episode featuring a bomb in the building (#6 on the list with 38 million viewers).

The list excluded duplicate titles so, for example, only one "American Idol" episode ranked rather than its multiple record-breaking premieres or finales.

Still, the breakdown gives a well-rounded view of the past ten years of television viewing habits. Not to be ignored is the fact that the newest entry on the list is "Idol's" 2007 six season premiere, a testament to today's fractured viewing habits, thanks to DVRs, Hulu and YouTube.

Other entries on the list include the "Joe Millionaire" finale (#3 with 40 million); the episode of "ER" that revealed who, of Lucy Knight and John Carter, would survive an attack by a schizophrenic patient (#4 with 39.4 million); and the finales of "Frasier" (#8 with 33.7 million) and "Everybody Loves Raymond (#9 with 32.9 million).

EW.com points out that for this season's episode of "The Office" in which Jim and Pam finally married, just 9.4 million people tuned in.
