The Pittsburgh Post-Gazette today published the first of a four-part series on the city's radio history. Pittsburgh is the home of KDKA, generally considered to be the first licensed commercial radio station, but as the story points out there is more to the city's radio legacy than that. Westinghouse, based in the city, helped monetize the growing radio history with its manufacturing of crystal sets. WHOO went on the air in 1948 featuring various ethnic programming and launched the career of Mary Dee Dudley, the country's first black disk jockey. Dave Garroway, the first host of NBC's Today show, worked at KDKA in the 1940s.
