Lux Radio Theatre, a long-run classic radio anthology series, was broadcast on the NBC Blue Network (1934-35); CBS Radio (1935-54), and NBC Radio (1954-55). Initially, the series adapted Broadway plays before it began adapting films. The hour-long radio programs were performed live before studio audiences becoming the most popular anthology radio series. It was broadcast for over 20 years and continued on television as the Lux Video Theatre through most of the 1950s.
Broadcasting from New York, the series premiered at 2:30pm, October 14, 1934, on the NBC Blue Network. The host was fictional producer, Douglass Garrick (portrayed by John Anthony). Doris Dagmar played Peggy Winthrop, who delivered the Lux commercials. Each show featured a scripted session with Garrick talking to the lead actors. Anthony appeared as Garrick from the premiere 1934 episode until June 30, 1935. Garrick was portrayed by Albert Hayes from July 29, 1935 to May 25, 1936, when the show moved to the West Coast.
Cecil B. DeMille took over as the host on June 1, 1936, continuing until January 22, 1945. On several occasions, he was temporarily replaced by various celebrities, including Leslie Howard and Edward Arnold. A clash over closed shop union rulings favored by the American Federation of Radio Artists ended DeMille's term as host.
The show employed several hosts over the following year, eventually choosing William Keighley as the permanent host, a post he held until 1952. After that, producer-director Irving Cummings hosted the program until it ended in 1955. For its airings on the Armed Forces Radio Service (for which it was retitled Hollywood Radio Theater), the program was hosted by Don Wilson in the early 1950s. (Source: wikipedia.org)
