2000 Plus (also called Two Thousand Plus and 2000+) was an American old-time radio series which ran from March 15, 1950 to January 2, 1952 in various 30-minute time slots. It was the first adult science fiction series on radio, airing one month prior to the better known Dimension X. During the 1950s, science fiction became a popular genre, and stories exploring future technologies, space expeditions and alien invasions were well received by the audience. Compared with other radio shows, 2000 Plus was an anthology program, and it used new and original material from Sherman H. Dryer, who scripted and produced the series with Robert Weenolsen. Aside from offering an exciting plot, Dryer and Weenolsen also carried out a consciousness in their stories – of the prevalent generation’s contemporary anxieties about the changing world, and the effects and dangers of technology to humankind. Cast members included Lon Clark, Joseph Julian, Henry Norell, Bill Keene, Bryna Raeburn and Amzie Strickland. Emerson Buckley conducted the music composed by Elliott Jacoby. Ken Marvin was the program's announcer, and the sound effects were by Adrian Penner
