Countdown for blastoff... X minus five, minus four, minus three, minus two, X minus one... Fire! [Rocket launch SFX] From the far horizons of the unknown come 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 presents... X Minus One.
—Original Title Sequence
First broadcast on 22 April 1955, X Minus One was a revival of Dimension X, airing on the NBC radio channel until 1958. This series holds the record for the longest running Science Fiction Radio Drama, a Genre Anthology of episodes that aired over a hundred different stories. The first fifteen episodes reused the Dimension X scripts with new talent behind the voices and sound effects.
This series was directed by Fred Wiehe, Daniel Sutter, and George Voutsas, lasting for one hundred twenty-six episodes. Most of the scriptwriting was by Ernest Kinoy or George Lefferts, but also bringing in new writers like Howard Rodman and William Welch. The scriptwriters would usually create adaptations, with a few scripts original to X Minus One.
Unlike most of its contemporaries, X Minus One would broadcast specifically to an adult audience* , adapting stories from Astounding Science Fiction and Galaxy Science Fiction for broadcast, adding sound effects and background noise to deepen the world. Stories included characters with gambling and addiction problems, criminal tendencies, and even a spaceship piloted by a computer with a female personality (who was being "made love to" by its "robot boyfriend").
The Pilot Episode, an adaptation of "And The Moon Be Still As Bright" by Ray Bradbury, aired on the 22nd, but weekly episodes began the 24th of April 1955, with a Radio original story, "No Contact" by George Lefferts (both episodes were Recycled from Dimension X). The final episode, an adaptation of "Gray Flannel Armor" by Finn O Donnevan, aired on 9 January 1958. An attempt to revive X Minus One was made on 27 January 1973, with episode number 126, an adaptation of "The Iron Chancellor" by Robert Silverberg.
The entire series survives today in digital form because of the Old Time Radio Researchers
, who have uploaded it to The Internet Archive. Other sources also provide a chance to listen and own DVD or CD copies.
X Minus One provides examples of:
- Adaptation Relationship Overhaul: In episode fifteen, Marilyn Lee Cross stows away aboard the Emergency Dispatch Ship to Woden in order to reunite with her husband Gerry. In the original story, Tom Godwin's "The Cold Equations", Gerry is Marilyn's older brother.
- Adaptational Backstory Change: In episode eighty-three, Jason Bernaides is a journalist who investigates Janet Boyce's encounter with the Flying Saucer in 1957 and later prevents her from drowning herself on June 25, 1962.

- Cannot Tell a Lie: One episode featured a reptilian "lawyer" whose race is incapable of lying (although they don't have to say the entire truth either). This is put to the test when a Jerkass character tries to get under another character's skin by mocking his home planet, who the latter keeps saying is the most beautiful place in the galaxy. The Jerkass gets the reptilian to admit the other character's planet has been ravaged by an asteroid shower and is hardly the paradise he thought it was, but to his shock the reptilian wholeheartedly agrees that the planet is the best place there is because the planet is named after the reptilian's word for "home".
- Character Narrator: In "Martian Sam", Joe, one of the ball club players, acts as narrator for the story, telling the audience about what he had seen and monologuing his opinions about the characters and settings.
- Feed the Mole: In "Project Trojan", Phase Three was identifying a German mole (Gogarty) and "losing" files connected to an unworkable Death Ray. Because they were only "losing" some of the files, it would look as if the lack of information meant the Allied powers had developed a solution.
- Fictional Document: In "Project Trojan", the war program is inspired by a story in Incredible Science Fiction Tales. To "research" for the project, the characters read more Science Fiction tales from the magazine.
- Find Out Next Time: The earliest episodes would give a short summary of the next week's story. After the series got partnered with Galaxy, it would sometimes describe one of the recent stories from the magazine, even when said story wasn't the basis of next week's episode. More of a "find out right now!" advertising of their print-medium partner.
- Future Imperfect: In one episode, two hunters, upon finding an alien, mention "Edison's automobile" and "Ford's electric lightbulb". To be fair, they're both blind drunk.
- Genre Anthology: X Minus One is a Science Fiction radio anthology series.
- Get A Hold Of Yourself Man: In episode eighty-three, adapted from Theodore Sturgeon's "A Saucer Of Loneliness", Jason Bernaides slaps Janet Boyce to prevent her from killing herself.
- Let X Be the Unknown: The "X" in the name
carries over from Dimension X, but now implies tension and excitement, the countdown for a rocket launch! Each episode warns of "a million could-be years on a thousand may-be worlds". - Loophole Abuse: In "Martian Sam", a Martian is hired as a pitcher for the Los Angeles Dodgers. Despite being only eighteen inches tall, the Martian's arm is 32 feet long, so most batters have a lot of trouble hitting the ball. Naturally, the Braves counter this by hiring an intelligent virus from Jupiter, so tiny that no pitch can be of the regulation height against them.
- Matter Replicator: In "Protective Mimicry", an adaptation of Algis Budrys's "Protective Mimicry", a galactic treasury agent investigates the source of some credit notes that appear to be genuine save that they all have the same serial numbers, and since the printing process is so fiendishly complicated he believes that someone invented a matter duplicator. It turns out the counterfeiter found an alien tree that made copies of whatever "attacks" it, like a paper airplane made from a 50 credit note. And during the final fight the agent runs into said tree, making it a bit difficult to get tickets back home for all of him.
- Mental Space Travel: In "The Last Martian", adapted from Fredric Brown's "The Last Martian", the titular character claims he escaped from a hospital on Mars to find the rest of his people all lying dead in the streets. Eventually he came to a copper column in the middle of a colosseum and touched it, then found himself in the body of a factory worker in New York. It turned out the others had abandoned their bodies on Mars and taken over humans to escape a plague. He was left behind because he was moronic by Martian standards - that is, as smart as an average human.
- Named by the Adaptation: In episode eighty-three, the woman who receives the telepathic message from the Flying Saucer is named Janet Boyce while the man who prevents the woman from committing suicide is named Jason Bernaides. This is adapted from Theodore Sturgeon's "A Saucer Of Loneliness", where the two characters are not named at all.
- Planet of Hats: One episode featured a reptilian alien coming to a mining planet for one of their workers (basically a milder version of a Furian). The reptile alien's hat is that they Cannot Tell a Lie (although they don't have to say the whole truth either) while the "Furian's" hat is being Hot-Blooded. Lampshaded by the "Furian": "You know how they say we're all good at bar fights?"
- Punctuated! For! Emphasis!: The show's title would be announced as "X! MINUS! ONE!".
- Secondary Character Title: In "Martian Sam", the title is based on one of the characters on the baseball team. The story, however, is told from Joe's perspective.
- Signing-Off Catchphrase: Early episodes would end their Find Out Next Time segments by calling out the show's title; "X! MINUS! ONE!".
- Spiritual Successor: This show was an effort to revive Dimension X, an earlier Science Fiction Genre Anthology which aired on NBC radio from 1950–1951. The director Fred Weihe worked on both, as did scriptwriters Ernest Kinoy and George Lefferts. Out of the first thirty or so episodes, they Recycled twenty-six of the scripts from the older Radio Drama.
- Whole Episode Flashback: Episode eighty-three, adapted from Theodore Sturgeon's "A Saucer Of Loneliness", begins on June 25, 1962 and then flashes back to 1957 to tell the story of Janet Boyce's difficulties after her refusal to divulge the contents of the message from the Flying Saucer.
- Works Set in World War II: "Project Trojan" is set during the war, and is about a team of counter-intelligence operatives trying to trick the Germans into chasing a fake scientific development.
- Worthless Yellow Rocks: In "Project Mastodon", an adaptation of Clifford Simak's "Project Mastodon", the protagonist got mixed up in a time-traveling get-rich-quick scheme by going to the past and investing in stocks that would rise and property loaded with a type of mineral that the seller told him had interesting scientific qualities but was basically worthless—uranium.
- "X" Makes Anything Cool: The title comes from the countdown for a rocketship; "X minus five, minus four, minus three, minus two, X minus one...". The association is due to the emphasis on Science Fiction for this radio program.
