World Broadcasting System, Inc., was an American recording service for the radio industry founded in 1929 by Percy L. Deutsch (1885–1968), with key investors and creative artists (Walter) Gustave Haenschen and Milton Diamond (both of whom had worked with Deutsch at the Brunswick Record Company) and was originally based in New York. The company recorded and, through its subsidiary, World Program Service, distributed discs to radio stations for broadcast. The discs themselves were 16 inches in diameter, vertical-cut, recorded at 33 1/3 r.p.m., and would play for 15 minutes per side on average. These recordings, which were made especially for radio studios that could not afford to maintain a studio orchestra, were not sold to the public.
