X Minus One was a science fiction radio drama series that gained recognition for its high production values and adaptation of stories from leading American authors of the era. The show featured adaptations of stories from popular science fiction magazines, Astounding and Galaxy, and brought to life the works of well-known authors such as Ray Bradbury, Isaac Asimov, and Poul Anderson. The series focused on futuristic adventures, exploring new dimensions in time and space, providing listeners with a glimpse into a million possible years on a thousand potential worlds.

The show aired on NBC from April 24, 1955, until January 9, 1958, totaling 124 episodes with one pilot or audition story. It occupied various time slots throughout its run in the 1950s, preventing it from generating a large following. X Minus One was an extension of a previous show, Dimension X, which aired on NBC from 1950-51. The first 15 scripts used for X Minus One were from Dimension X, but the series soon found its own niche. A revival of the series was attempted in 1973, but it only lasted until 1975. Today, the series has survived in high quality and remains enjoyable for fans of classic science fiction.
