List of the big bang theory episodes

The Big Bang Theory is an American comedy television series created and executive produced by Chuck Lorre and Bill Prady.

Like the name of the series itself, with the exception of the first episode—"Pilot"—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.

As of November 21, 2013, 144 episodes have aired.

The Big Bang Theory was renewed for a seventh season, which premiered on September 26, 2013.[1]
