Gilligan’s Island aired for three seasons on CBS from 1964 to 1967.The sitcom featured Bob Denver, Alan Hale, Jr., Jim Backus, Natalie Schafer, Russell Johnson, Tina Louise, and Dawn Wells.
Gilligan’s Island ran for a total of 98 episodes. The first season, consisting of 36 episodes, was filmed in black and white. These episodes were later colorized for syndication. The show’s second and third seasons (62 episodes) and the three (!!) television movie sequels were filmed in color.
Inexplicably, the witless show enjoyed solid ratings during its original run, then grew in popularity during decades of syndication, especially in the 1970s and 1980s when many markets ran the show in the late afternoon after school. (Adapted from Wikipedia)
