The Big Bang Theory is an American comedy television series created and executively 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 that is stated in that episode.
In March 2017, CBS announced that the series was renewed for two more years, leading the show to a total of 12 seasons. The eleventh season premiered on September 25, 2017. As of November 2, 2017, 237 episodes of The Big Bang Theory have aired. There was also an unaired pilot which CBS did not broadcast.
