List of The Big Bang Theory episodes

This is a list of episodes of The Big Bang Theory, an American comedy television series created and executive produced by Chuck Lorre and Bill Prady.

Like the name of the series itself, episode titles of The Big Bang Theory always start with "The", and resemble the name of a scientific principle, theory or experiment, whimsically referencing a plot point or quirk in the episode. The series pilot is an exception to this rule. In the first four seasons, the most popular final words in an episode title are reaction, hypothesis and formulation - each occurring in three titles.

As of December 8, 2011 (2011 -12-08), 98 episodes have aired.
