The show was created, produced, and hosted by Bob Wilkins in the guise of Captain Cosmic, airing serials, primarily featuring Japanese superheroes.
The show was created after Wilkins and his family vacationed in Hawaii and experienced the explosion of live action Japanese superhero television series broadcast on Honolulu's KIKU TV-13, and was further spurred onto the airwaves in the wake of Star Wars, capitalizing on the popularity of science fiction.
Captain Cosmic would feature guests on the show, from local fans and celebrities, to actors from science fiction films and television series, such as Anthony Daniels and David Prowse.
A weekly message would be shown that only members with decoder cards would be able to decipher (the code consisted of a three-shift alpha replacement) on upcoming events and new shows being added to the line-up.
Despite its popularity, Wilkins decided to leave Captain Cosmic at the 11th Hour, instead of renewing his contract; he was transitioning out of television, in the wake of bowing out of hosting Creature Features after eight years (January 9, 1971 to February 24, 1979), and return to concentrating on his own Advertising Agency.
