The very first major science fiction series for adults on radio was Mutual Broadcasting System's
2000 Plus (1950-1952). An anthology program,
2000 Plus used all new material rather than adapting published stories. Just one month after its premiere, NBC Radio began airing
Dimension X (1950-1951), which dramatized the written work of such young writers as Ray Bradbury, Robert Heinlein, Isaac Asimov, and Kurt Vonnegut. In 1955, NBC relaunched
Dimension X as
X Minus One (1955-1958), drawing from stories that had been published in the two most popular science fiction magazines at the time:
Astounding and
Galaxy. 17 of 30 episodes of
2000 Plus, all 50 episodes of
Dimension X, and all 125 episodes of
X Minus One are available for free download as individual mp3s from the Internet Archive.
The shows are also available in free zip file compilations:
