science fiction, and youth science fiction (children and teenagers). Examples of the former are My Favorite Martian, CBS, 1963–66; Mork & Mindy, ABC 1978–1982; ALF, NBC, 1986–90; and 3rd Rock from the Sun, NBC, 1996–2001. There are many examples of youth science fiction. They are characterized by relatively simple plots, and characters despite lacking production value. The animated Colonel Bleep launched in 1957 and went on to a long run in first-run syndication. A British import using marionettes was Fireball XL5, initially released in 1962. Fireball XL5 was a rocket ship protecting Sector 25 of the Solar System. Also first released in 1962 was Space Angel, a cartoon. “Space Angel” was the code name for Scott McCloud, captain of a space ship. The Jetsons originally ran on ABC from 1962 to 1963. George Jetson was the head of a family of the future. Usually, Jonny Quest, (1964–65), was a cartoon adventure, but with science fiction technology, e.g. a rocket ship and a hovercraft. Higher production values were quite evident in the Zenon trilogy released by the Disney Channel. Zenon: Girl of the 21st Century was released in 1999, Zenon: The Zequel was released in 2001, and Zenon: Z3 was released in 2004. Notes References Bibliography Asherman, Allan (1986).
