Space Ghost is an American Saturday-morning superhero animated television series produced by Hanna-Barbera Productions, first broadcast on CBS from September 10, 1966, to September 16, 1967, and continued reruns until September 7, 1968.[1] The series was composed of two unrelated segments, Space Ghost and Dino Boy in the Lost Valley.[2] The series was created by Alex Toth[3] and produced and directed by William Hanna and Joseph Barbera. Sometimes, it is alternatively called Space Ghost & Dino Boy to acknowledge the presence of both shows.[4] The Space Ghost segments were seen again in the 1976 series Space Ghost and Frankenstein Jr. (which replaced the Dino Boy segments with the Frankenstein Jr. ones from fellow Hanna-Barbera show Frankenstein Jr. and The Impossibles), which aired on NBC from November 27, 1976, to September 4, 1977, after NBC put The Kids From C.A.P.E.R. on hiatus.[5][better source needed]
