Produced by Albert McCleery, NBC`s Cameo Theatre (1950) was a live dramatic anthology series that ran in various time slots from 1950 to 1955. With minimal props and sets, Cameo Theatre (1950) borrowed the concept of intimate theater-in-the-round, popularized by influential producer-director `Margo Jones` (1912-1955) during the years 1947 to 1955 at her Dallas theater; the first U.S. professional arena theater, it also pioneered the use of closed-circuit television so actors waiting offstage for their cues could see what was happening on the stage. While live television dramas were often limited by camera placement, McCleery solved the problem by eliminating all large scenery or backdrops on his Cameo Theatre (1950). Since the background was solid black, camera operators had total freedom and could easily move about in the darkness to pick up any close shot or unusual angle as directed. Thus, the emphasis was on the actors and close-up characterizations, seen without distractions.
