Originally ran for only 24 episodes during the 1962-1963 TV season. In 1985 the program was revived, with new episodes designed to syndicate alongside the originals.
An episode of another Hanna-Barbera show, The Flintstones, in which the Flinstones and the Rubbles use a time machine at the Worlds' Fair to travel to the future (episode 4.18 "Time Machine," 15 January 1965) features a distinctly Jetson-esque 21st century.
George and the rest of the Jetson clan appeared in print ads for Electrasol Dish Washer tabs and were the subject of a series of collectible tins. (2004-05)
The design of the Jetsons' flying car was inspired by a 1954 Ford concept car, the FX-Atmos, notable for its all-glass bubble canopy, dashboard radar screen and jet-plane-like tail fins.
