When Star Trek first came on NBC in 1966, it was not successful to begin; ratings were low and advertising revenue was very little. Even at the end of the first season of Star Trek, there were already calls in the network to cancel the series due to its low Nielsen ratings. Bay Area Creature Features host John Stanley in his memoir I Was a TV Horror Host relates how Desilu head Lucille Ball at that time "single handedly" kept Star Trek from being removed from the NBC-TV lineup."
Close to the end of the second season the show was still in danger of being canceled. Its fans succeeded in giving it a third season; but NBC moved the show to the "Friday night death slot" at 10 PM.Star Trek was finally canceled at the end of the third season, making 79 episodes in total. However, this was enough for the show to be stripped in syndication, allowing it to become very popular and gather a large cult following during the 1970s. After the success of the program, five additional television series and eleven movies, including the newest movie Star Trek, which came out in May 2009. Guinness World Records lists the original Star Trek as having more spin-offs than any other television show in history.
