WLOU

WLOU was an R&B station in (W) LOUisville, Kentucky.  In 1949 there were only four radio stations in the United States with formats that catered directly to African-Americans.  WLOU switched to a "soul" music format in 1951 and by 1954 there were at least 200 such stations.  At that time AM 1350 was white-owned and proclaimed in a Rounsaville Radio print ad to be "Louisville's only all Negro-Programmed Station!"
WLOU currently carries a Black Gospel format.
