Star Trek originated as a television series in 1966, although it had been in the planning stages for at least six years prior to that.[2] Although The Original Series was canceled after its third season due to low ratings, it has served as the foundation for five additional Star Trek television series.[3] Altogether, the six series comprise a total of 726 episodes and ten theatrical films (with an 11th in the works) across twenty-two different television seasons (twenty-nine, if one separately counts seasons running concurrently), making it the second most prolific science-fiction franchise in history after Doctor Who.
