8XK/KDKA
Westinghouse Radio Station KDKA was a world pioneer of commercial radio broadcasting. Transmitting with a power of 100 watts on a wavelength of 360 meters, KDKA began scheduled programming with the Harding-Cox Presidential election returns on November 2, 1920. A shed, housing studio and transmitter, was atop the K Building of the Westinghouse East Pittsburgh works. Conceived by C.P. Davis, broadcasting as a public service evolved from Frank Conrad's weekly experimental broadcasts over his amateur radio station 8XK, attracting many regular listeners who had wireless receiving sets. Most radio historians assert that radio broadcasting began in 1920 with the historic broadcast of KDKA. Few people actually heard the voices and music which were produced because of the lack of radio receivers at that time. The public, however, was overcome by a radio craze after the initial broadcast. Radio became a product of the mass market. Manufacturers were overwhelmed by the demand for receivers, as customers stood in line to complete order forms for radios after dealers had sold out. Between 1923 and 1930, 60 percent of American families purchased radios. Families gathered around their radios for night-time entertainment. As radio ownership increased, so did the number of radio stations. In 1920, KDKA was not actually the only operating radio station, but it remains a benchmark in most accounts. By 1922, 600 radio stations had sprung up around the United States.
