Original Network Run: September 1964 to April 1967
Gilligan's Island first aired on CBS on September 26, 1964 and ran for three full seasons, concluding on April 17, 1967. It was a midseason replacement in fall 1964 and was canceled after 98 episodes. During its network life, it occupied a family-friendly hour slot and built a loyal audience despite moderate ratings.
Season-by-Season Dates and Episode Counts
Each season reflected the evolving production constraints and format experimentation, yet maintained the stranded-castaway premise audiences enjoyed.

Production Context
Created by Sherwood Schwartz and produced by United Artists Television, the show was filmed in black-and-white for its first season, then switched to color in Season 2. The move to color coincided with the growth of syndicated reruns and helped the series maintain relevance in a competitive marketplace.
First-Run Syndication and The Return of Gilligan's Island (1967–1970s)
After its CBS cancellation, Gilligan's Island entered first-run syndication in the late 1960s, airing in many local markets as an afternoon hour-long block. Stations valued the series for its family appeal and simple, broadly suitable storylines. The TV movie The Return of Gilligan's Island premiered in 1978, reintroducing the cast to viewers and leading to two additional TV movies over the next decade.
Reruns, TV Movies, and Revival Attempts (1970s–1990s)
Throughout the 1970s and early 1980s, Gilligan's Island remained a staple of weekend and late-afternoon syndication across the U.S. In 1979, a sequel animated series aired on NBC, and in the 1990s, two TV reunion movies brought the cast back together. These extensions helped cement the show's presence in popular culture long after its original episodes had ended.
Cable, Streaming, and Modern Availability
In the cable era, the series found a home on TBS and later Turner Classic Movies, while streaming platforms expanded its reach to global audiences. As of the 2020s, episodes are typically available via multiple licensed services, which has introduced the show to new generations and sustained ongoing interest in its cast and production history.
