With its national prominence as a clear channel giant established, WTAM became a valuable radio property. NBC purchased WTAM on October 16, 1930, and the studios were moved to the Auditorium Building. The station became a major link in the NBC Red Network, contributing some programming to the network. Around 1930, Gene Carroll and Glenn Rowell brought their vaudeville humor to WTAM with the "Gene and Glenn" show. The duo became famous for their characters "Jake & Lena". WTAM originated the program for nationwide broadcast on the NBC Red Network, and it aired six days a week for five years. WTAM also originated the venerable "Lum and Abner" show on the NBC Red Network five days a week during one year of its run from May 22, 1933 to March 30, 1934, sponsored by the Ford Dealers of America.
