Spinoffs/Sequels/Copycats: The show's first season aired in 1962-1963, and its second and third seasons were made in 1985-1987. There were also three animated TV shows, including The Jetsons Meet The Flintstones and Jetsons: The Movie. Robert "Spy Kids" Rodriguez is reportedly in talks to direct a live-action Jetsons.
Stunt casting: Don Messick, who played Astro the dog, also played Scooby Doo and Muttley with a similar "ruh-roh" vocalization.
Design breakthrough: The Jetsons' future city has come to exemplify a kind of retro-futurist architecture, with pin-cushion shaped houses high up on stilts and space-needle-esque buildings. When design critics want to refer in passing to a super-stylized flying-car vision of future urban life, they use The Jetsons as shorthand for a whole style.
