About this Audiobook

by Old Time Radio Researchers Group

📖 Synopsis & Plot Overview

X MINUS ONE X Minus One aired on NBC from 24 April 55 until 9 January 58 for a total of 124 episodes with one pilot or audition story. There was a revival of the series in 1973 when radio was attempting to bring back radio drama and it lasted until 1975. The show occupied numerous time slots through out its run in the 50's and thus was never able to generate a large following.

🔍 Key Themes & Narrative Depth

X Minus One was an extension of Dimension X which aired on NBC from 1950-51. The first fifteen scripts used for X Minus One were scripts used in the airing of Dimension X; however, it soon found its own little niche. The stories for the show came from two of the most popular science fiction magazines at the time; Astounding and Galaxy.

Adaptations of these stories were performed by Ernest Kinoy and George Lefferts. They even wrote a few original stories of their own. The writers of the magazine stories were not well known then but now are the giants of today.

These stories came from the minds of Ray Bradbury, Isaac Asimov, and Poul Anderson to name a few. This series has survived from its original airing in high quality to be enjoyed today. NOTE: Updated with Version 3 files (14-May-2011).

Couldn't put it down — figuratively speaking

I specifically look for audiobooks with a natural narration style — nothing worse than robotic delivery. This nails it. Very easy to listen to for long stretches.

Exactly what I needed right now

Some chapters hit differently depending on where you are in life. I think I needed to hear X Minus One - Single Episodes right now. Perfect timing, perfect book.

Highly recommend to anyone who loves this genre

Good balance of depth and accessibility. You don't need a background in this topic to follow along, but it never feels dumbed down either. Well done.

Listened during a long drive — made the trip

Finished it in four sittings. Usually takes me weeks to get through an audiobook. Says a lot about how gripping X Minus One - Single Episodes is.
