Six issues of a “Captain Video” comic book were published by Fawcett Comics in 1951. The rival space adventure programs Tom Corbett and Space Patrol shortly thereafter had their own comic books as well. Some of these comics were used as the basis for a British TV Annual, a hardcover collection produced in time for Christmas, which also made the claim that man would venture into space in 1970 and would reach the moon by 2000.

Captain Video and His Video Rangers is an American science fiction television series that aired on the DuMont Television Network and was the first series of its genre on American television.

The series aired between June 27, 1949, and April 1, 1955, originally on Monday through Saturday at 7 p.m. ET, and then Monday through Friday at 7 p.m. ET. A separate 30-minute spinoff series called The Secret Files of Captain Video, aired Saturday mornings, alternating with Tom Corbett, Space Cadet, from September 5, 1953, to May 29, 1954, a total of 20 episodes.

Researcher Alan Morton estimates there were a total of 1,537 episodes (counting the 20 Saturday morning episodes), although few of them exist after the destruction of the original broadcasts, which was commonplace at that time. Sponsors included Post Cereals, Skippy Peanut Butter, DuMont-brand television sets, and Power House candy bars. Premiums sold via the show included a flying saucer ring, a “secret seal” ring, cast photos, electronic goggles, a “secret ray gun”, a rocket ship key chain, decoders, membership cards, and a set of 12 plastic spacemen.
