(LOS ANGELES) -- When The Big Bang Theory began production on its 276th episode on Wednesday, it became the longest-running multi-camera sitcom in American TV history, according to Warner Brothers.
The previous record of 275 belonged to Cheers.
For the record, the longest-running live-action sitcom of any kind is The Adventures of Ozzie and Harriet, which aired 435 episodes from 1952-1966. The king of the hill, with 657 episodes, however, is The Simpsons.
The Big Bang Theory airs Thursdays at 8 p.m. ET on CBS, with the one-hour series finale airing May 16.
