The classic sitcom I Dream of Jeannie went through a lot of transformations in its five seasons. By the time the show had reached its fifth and final season, Tony Nelson had gone from Captain to Major, and from “master” of Jeannie to Jeannie's husband. The show had run its course, though the last episode, which aired in May 26, 1970, indicated the show’s writers were not concerned with wrapping up the series. It ended with an unremarkable episode about astronaut Tony’s image being used to endorse homemade chili.
