The original version, broadcast live on the DuMont Television Network Saturday evenings for 30 minutes, from March 21 to June 13, 1953, starred Vaughn Taylor as an elderly janitor, Ernest P. Duckweather, cleaning-up after midnight in a TV studio. Tinkering with a TV set, he somehow made contact with the planet Jupiter, and two of its inhabitants, Johnny Jupiter and his colleague B-12, both of whom were hand puppets voiced by series writer Jerome Coopersmith and Carl Harms. The often sharp humor of the series was based on Duckweather trying to explain and justify earth customs to the natives of Jupiter, who could view them on their own TV sets. As an example, the program covered the US fad for 3-D movies, which came and went rapidly in 1953. The Jovian natives explain that their own movies were originally in 3-D but rapidly evolved to 7-D before dropping to 1-D, which is the format all Jovians prefer today.

ABC version
Another weekly 30-minute version of the series, filmed and sponsored by M&M's Candies, appeared on ABC from September 5, 1953, to May 29, 1954. The concept was completely different from the DuMont version of the series. Wright King, as Duckweather, was now an eager young employee of a TV repair shop; most of each episode consisted of live-action situation comedy involving Duckweather, his boss Horatio Frisby, the boss's daughter Katherine, and one or more guest-stars. The puppets appeared only when Duckweather needed help or advice; the magic TV set now brought in three Jovian hand puppets: Johnny Jupiter; a cube-headed robot, Major Domo; and a cylinder-headed, glasses-wearing Reject the Robot, all voiced by Gil Mack. On at least one episode Reject's brother Defect appeared. The solution to Duckweather's problem generally involved beaming the bumbling Reject to earth, where he was played by new puppeteer Gene London wearing a large prop robot suit. Apart from the robot suit, the new series was not geared towards children. The series was canceled after one 39-episode season. In this second series, Jerry Coopersmith was producer and script editor only.

Copies of the ABC version of the program have survived and have been released on DVD.
