Star Trek: The Original Series
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."
