The early commercial development was in the hands of the Westinghouse Corporation. The founder, George Westinghouse, was adept at acquiring patents and developing products
based upon those patents. He acquired from the Serbian inventor Nicola Tesla the patents
for the alternating current (AC) electrical motor/generator. From Edwin Armstrong Westinghouse acquired patents for the circuitry of the early radios. Armstrong was a true technical genius who invented not just one type of radio receiver but three. The first vacuum tube radio receivers developed by Armstrong (1912) used a circuitry called the regenerative circuit based upon feedback. This also became the basis for radio transmitters. Later, while in Paris during World War I with the U.S. Army Signal Corps, Armstrong invented a much more powerful amplifier circuit called the superheterodyne circuit. This is the basis for radio, television and radar reception to this day. This is AM (amplitude modulation) radio technology. In the early 1920's Westinghouse began manufacturing radio receiving sets based upon Armstrong's AM patents. Westinghouse established the first commercial radio broadcasting station, KDKA, in Pittsburgh, Pennsylvania in 1920.
