Dupont Theater (aka Cavalcade of America) was an anthology drama series that was sponsored by the DuPont Company, although it occasionally presented a musical, such as an adaptation of Show Boat, and condensed biographies of popular composers. It was initially broadcast on radio from 1935 to 1953, and later on television from 1952 to 1957. Originally on CBS, the series pioneered the use of anthology drama for company audio advertising.
