KDKA (AM)

KDKA (1020 kHz) is a radio station licensed in Pittsburgh, Pennsylvania. Created by the Westinghouse Electric Corporation on November 2, 1920, it is the world's first commercial radio station, a distinction that has also been challenged by other stations, although it has claimed to be the "world's first commercially licensed radio station": WWJ in Detroit, Michigan (also a CBS Radio station), lists its "First Air Date" as August 20, 1920. KDKA is currently owned and operated by CBS Radio, with studios located at the combined CBS Radio Pittsburgh facility on Foster Drive in Green Tree and transmitter in Allison Park.
