Radio Trivia: WLOU was Louisville's sixth radio station, coming on the air in 1948 just days before WKLO. It originally was a 1000-watt daytime operation, but power was increased many years later to 5000 watts. In 1951 WLOU became one of the country's first "Negro radio stations" using black deejays and playing music, features and news of interest to the African-American community.

"WLOU disc jockey and all-around airman Tobe Howard entertains his audience with breezy patter and 'soul sound' music. His station, part of the Rounsaville chain, beams primarily to the Negro community. WLOU was the third station in the U.S. to devote its programming efforts to the Negro listener and is part of the first chain-operated group of Negro-programmed stations in the country."

"William E. Summers, III (left), new general manager at WLOU, had been with the station 15 years ago as an announcer and sales manager before his recent promotion. Engineer Murrell Rafferty keeps tabs on the technical facets of the station's operation. WLOU programming is directed primarily to Louisville's negro citizens, but the staff is fully integrated."
