Today in 1950 , NBC began airing the science fiction series Dimension X . It flew by the seat of its pants as an non-sponsored, sustaining program, but did just fine for itself. It enjoyed immense success and popularity, and would eventually evolve into another chestnut, X Minus One . Staff writer Ernest Kinoy adapted top-notch sci-fi works by the likes of Robert Heinlein, Isaac Asimov , and Kurt Vonnegut; acting talent included Joseph Cotten , Leslie Wood, and John McGovern.

It had graced the pages of The Saturday Evening Post just months earlier (Dec. 24, 1949). As always, Norman Rose hosted, with Bob Warren announcing.
