Broadcast History: 1955 to 1958
Dimension X was the framework for X Minus One. It was an extension of Dimension X, sometimes even broadcasting the same stories. X Minus One was a thirty-minute science fiction series totalling 113 episodes and throughout its three years of broadcasting, it always used the same opening, a rocket-launch countdown. The stories were strict science fiction striking out into deep space, exploring thousands of other worlds and galaxies and, the much more exciting, power struggles with aliens. Although the stories were not always human triumphs, sometimes the aliens won!
