. . . I am just slightly surprised that I was unaware of the fine sci-fi radio series X Minus One and its predecessor, Dimension X, until about 10 years ago. This situation is probably due to the fact in the heyday of 1950s and 1960s television, I just did niot take radio very seriously. I was aware of radio drama -- Have Gun Will Travel, The Whistler, The Shadow and the ilk.

But I was not aware of X Minus One or Dimension X until I heard a promo for them on my car's Sirius satellite radio.

What a happy discovery!
