2000 Plus

2000 Plus was an American SF radio anthology series that ran on the Mutual Broadcasting System network from March 15, 1950, to January 2, 1952. It was arguably the first adult science fiction series on radio, airing around one month prior to the better known Dimension X. The series was the creation of Sherman H. Dryer, who scripted and produced the series with Robert Weenolsen. Just under a hundred episodes were produced, but sadly only sixteen survive (an episode titled 'The Doom Machine' is thought to exist, but does not appear to be in public circulation). All the episodes were based on original scripts, unlike subsequent anthology series such as Dimension X and X Minus One, which frequently adapted pre-existing stories.
