<P> Amos' n' Andy was officially transferred by NBC from the Blue Network to the Red Network in 1935, although the vast majority of stations carrying the show remained the same . Several months later, Gosden and Correll moved production of the show from NBC's Merchandise Mart studios in Chicago to Hollywood . After a long and successful run with Pepsodent, the program changed sponsors in 1938 to Campbell's Soup; because of Campbell's closer relationship with CBS, the series switched to that network on April 3, 1939 . </P> <P> In 1943, after 4,091 episodes, the radio program went from a 15 - minute CBS weekday dramatic serial to an NBC half - hour weekly comedy . While the five - a-week show often had a quiet, easygoing feeling, the new version was a full - fledged sitcom in the Hollywood sense, with a regular studio audience (for the first time in the show's history) and an orchestra . More outside actors, including many black comedy professionals, such as Eddie Green, were brought in to fill out the cast . Many of the half - hour programs were written by Joe Connelly and Bob Mosher, later the writing team behind Leave It to Beaver and The Munsters . In the new version, Amos became a peripheral character to the more dominant Andy and Kingfish duo, although Amos was still featured in the traditional Christmas show, where he explains the Lord's Prayer to his daughter, Arbadella, voiced by Elinor Harriot and later by the Asian American Barbara Jean Wong . The Christmas show also became a part of the later television series . The later radio program and the TV version were advanced for the time, depicting Blacks in a variety of roles including successful business owners and managers, professionals and public officials, in addition to the comic characters at the show's core . It anticipated many later comedies featuring working class characters (both Black and White) including All in the Family, The Honeymooners and Sanford and Son . </P> <P> By the fall of 1948, the show was back on CBS again . In that same year, Correll and Gosden sold all rights to Amos' n' Andy to CBS for a reported 2.5 million dollars . </P> <P> Advertising pioneer Albert Lasker often took credit for having created the show as a promotional vehicle . After the associations with Pepsodent toothpaste (1929--37) and Campbell's Soup (1937--43), primary sponsors included Lever Brothers' Rinso detergent (1943--50), the Rexall drugstore chain (1950--54) and CBS' own Columbia brand of television sets (1954--55). President Calvin Coolidge was said to be among the devoted listeners . Huey P. Long took his nickname of "Kingfish" from the show . At the peak of the popularity, many movie theaters began the practice of stopping the films for the 15 minutes of the Amos' n' Andy show and then playing the program through the theater's sound system or simply by placing a radio on the stage . Some theaters attempted to attract patrons by noting the fact that they offered the broadcast in their advertisements . NBC sought to stop the practice by charging the theaters who did so with copyright infringement, claiming that charging admission for a free broadcast was not legal . </P>
