Once upon a time, before science fiction (in the form of monster movies and comic-book franchises) took over the cineplex, anthology shows on radio and television provided a steady diet of short tales of the fantastic.

Case in point was the short-lived NBC radio program Dimension X, which ran from 1950 to 1951 and advertised itself as “adventures in time and space, told in future tense.”

During the show’s tenure, they broadcast work by some of the genre’s greatest practitioners, from Isaac Asimov and Robert Bloch to Ray Bradbury and Robert A. Heinlein. Now, thanks to the memory machine that is the Internet, you can listen to some of those programs at the Internet Archive. Make sure to check out Bradbury’s “There Will Come Soft Rains,” originally collected in The Martian Chronicles and one of the greatest, saddest testimonies ever penned on the folly of war.
