Gilligan's Island is an American sitcom created and produced by Sherwood Schwartz and originally produced by United Artists Television. The situation comedy series featured Bob Denver, Alan Hale, Jr., Jim Backus, Natalie Schafer, Russell Johnson, Tina Louise, and Dawn Wells. It aired for three seasons on the CBS network from September 26, 1964, to April 17, 1967. Originally sponsored by Philip Morris & Company and Procter & Gamble, the show followed the comic adventures of seven castaways as they attempted to survive (and in a later movie escape from) the island on which they had been shipwrecked. Most episodes revolve around the dissimilar castaways' conflicts and their failed attempts (invariably Gilligan's fault) to escape their plight.
