Star Trek: The Original Series, or simply Star Trek, was a popular sci-fi show that ran on NBC from 1966 to 1969. The series ran for a total of 3 seasons and 79 episodes, not including the pilot "The Cage". The series starred William Shatner as Captain James T. Kirk and Leonard Nimoy as Spock. The show quickly gathered a large fan base known as Trekkies, which continued to grow even after NBC canceled the show. It didn’t take long for the series to return as an animated form and eventually into several movies starring Shatner and Nimoy.
