Space Patrol is a science fiction adventure series that was originally aimed at juvenile audiences of the early 1950s via television, radio, and comic books. However, it soon developed a sizable adult audience such that by 1954, the program consistently ranked in the top 10 shows broadcast on a Saturday.
The success of the TV show spawned an almost instant radio version, which ran from 4 October 1952 to 19 March 1955 producing approximately 129 episodes. The same cast of actors performed on both shows. The writers, scripts, adventures and director had some crossover between the radio and TV incarnations however; the radio broadcasts were not limited by the studio sets and became more expansive in scope and story than the television versions. Although there was seldom any deliberate crossing-over of storylines, some of the television villains regularly appeared on the radio (notably Prince Bacarratti), and during the 'Planet X' story both the TV and radio versions explored the rogue planet's invasion of the Space Patrol universe.
While the radio series lacked the adult sophistication of sci-fi shows such as the later day X Minus One, it was enjoyed as a Golden Age space opera popularized in the 1930s, the days of science fiction's infancy, by pioneering magazine editor Hugo Gernsback and it is prized by "Old Time Radio" collectors today as one of radio's most enjoyable and fascinating adventures. Unfortunately only around 117 of the original broadcasts survive. (Source: wikipedia.org)
