Dimension X was first heard over NBC on April 8, 1950 and ran until September of 1951.  Although not the first adult
science fiction radio series, Dimension X is remembered because of the quality of the shows.  Some of the writers
whose works were dramatized were
Ray Bradbury, Robert Block, Robert A. Heinlein, Isaac Asimov and Kurt
Vonnegut. Many of the stories appeared in science fiction magazines such as Amazing, Astounding and Thrilling
Wonder. These stories were adapted for radio by in-house scriptwriter George Lefferts.

The narrator was Norman Rose. It was one of the first shows to be recorded on tape.
