Dimension X was a science fiction radio program that showcased the works of renowned writers such as Ray Bradbury, Robert Bloch, Robert Heinlein, Isaac Asimov, and Kurt Vonnegut. The show's scriptwriter Ernest Kinoy adapted these masterpieces and also contributed some original stories. Dimension X's gripping plotlines often delved into themes of adventure, time, and space—all set in future tense. The program featured a variety of talented actors, including Joe Di Santis, Wendell Holmes, Jan Miner, and Mason Adams. Directed by Fred Weihe and Edward King, the series' signature echoed the title "DIMENSION X X X X X x x x x x" and heavily relied on the "X" factor, engaging audiences in a thrilling audio experience.

Broadcast on NBC Radio, Dimension X aired from April 8, 1950, to September 29, 1951. Throughout its run, the series released 50 episodes, 13 of which were broadcast live, while the remainder were prerecorded. The show was mostly unsponsored but was backed by Wheaties for two months starting in July 1950. Dimension X garnered a strong following, with all of its episodes still accessible today. This unique radio program preceded the television era and was followed by another NBC series, X Minus One (1955-58), which featured many of the same actors and scripts as Dimension X.
