Pohl On Radio
Frederik Pohl also penned a number of the original stories that were adapted for the longest running, and arguably finest, Sci-Fi radio series ever produced, X Minus One, which aired on NBC for almost three years (1955-58) and spanned 130 episodes, all of which survive (and are available for free at the Internet Archive -- https://archive.org/details/OTRR_Certified_X_Minus_One).
The program opened with announcer Fred Collins delivering the countdown, leading into this classic introduction (although later shows were partnered with Galaxy Science Fiction rather than Astounding Science Fiction):
Countdown for blastoff... X minus five, four, three, two, X minus one... Fire!

From the far horizons of the unknown come transcribed tales of new dimensions in time and space. These are stories of the future; adventures in which you'll live in a million could-be years on a thousand may-be worlds.
The National Broadcasting Company, in cooperation with Street and Smith, publishers of Astounding Science Fiction, presents... X --- Minus --- One.
I especially recommend Pohl’s "Tunnel Under the World," from March 14, 1956. Though he will be missed, his gifts will continue to enrich us 'til the end of time.
