(LOS ANGELES) — After 12 years and 279 episodes, The Big Bang Theory broadcast its final episode Thursday night in a two-part series finale. 

The show’s 12-season tenure is the longest to date of any American sitcom that’s recorded before a live studio audience.  In second place, with 11 seasons each, are Cheers, Frasier, Happy Days, The Jeffersons, Married: With Children, and, if you count the just-canceled one-season revival, Murphy Brown.

Total number of seasons: 12

Number of episodes: 279, including the two-part series finale.
