Dimension X ran on NBC from April 8, 1950, to September 29, 1951: fifty episodes, and all of them survive. Norman Rose opened each one with "Adventures in time and space, told in future tense." It adapted stories by Ray Bradbury, Robert Heinlein, Isaac Asimov, Kurt Vonnegut and Jack Williamson. The first thirteen shows went out live. NBC's X Minus One later reused many of its scripts and actors.
