One year after Bewitched became a hit for ABC, NBC wanted a piece of the supernatural sitcom action. The end result was I Dream of Jeannie, which didn't last quite as long (5 seasons as opposed to 8 for Bewitched), but was just as popular, thanks to the chemistry of its stars, Barbara Eden & Larry Hagman.
Series creator Sidney Sheldon is better known now as an acclaimed author (i.e. The Other Side of Midnight), but Jeannie actually put him on the map in the first place. His concept was rather simple. Astronaut Anthony Nelson (Hagman) finds a bottle washed up on a beach, cleans it up, and out pops Jeannie (Eden), who instantly develops an attraction to Nelson, such that she becomes jealous of any other woman that crosses his path. This same concept was revisited in Hanna-Barbera's animated reboot, Jeannie, which lasted just one season in 1973 for CBS, but with a teenager as the male protagonist.
In the course of the series' 5 seasons, Nelson, along with best buddy and sidekick Roger Healey (Bill Daily) is promoted to Major, and he & Jeannie eventually wed, which would actually mark the beginning of the end for the series. Eden, like Elizabeth Montgomery over on Bewitched, would don a black wig and play Jeannie's twin sister (as opposed to Serena being Samantha's cousin) in a few episodes to create more chaos.
