context_page_description: The RCA Corporation was a major American electronics company, which was founded as the Radio Corporation of America in 1919. It was initially a patent trust owned by General Electric, Westinghouse, AT&T Corporation and United Fruit Company. In 1932, RCA became an independent company after the partners were required to divest their ownership as part of the settlement of a government antitrust suit.
  An innovative and progressive company, RCA was the dominant electronics and communications firm in the United States for over five decades. RCA was at the forefront of the mushrooming radio industry in the early 1920s, as a major manufacturer of radio receivers, and the exclusive manufacturer of the first superheterodyne models. RCA also created the first nationwide American radio network, the National Broadcasting Company. The company was also a pioneer in the introduction and development of television, both black and white and especially, color television. During this period, RCA was closely identified with the leadership of David Sarnoff. He was general manager at the company's founding, became president in 1930, and remained active, as chairman of the board, until the end of 1969.
context_section_description: The introduction of organized radio broadcasting in the early 1920s resulted in a dramatic reorientation and expansion of RCA's business activities. The development of vacuum tube radio transmitters made audio transmissions practical, in contrast with the earlier transmitters which were limited to sending the dits-and-dahs of Morse code. Since at least 1916, when he was still at American Marconi, David Sarnoff had proposed establishing broadcasting stations, but his memos to management promoting the idea for sales of a "Radio Music Box" had not been followed up at the time.
  Starting around 1920 a small number of broadcasting stations began operating, and soon interest in the innovation was spreading nationwide. In the summer of 1921, a Madison Square Garden employee, Julius Hopp, devised a plan to raise charitable funds by broadcasting, from ringside, the July 2, 1921 Dempsey-Carpentier heavyweight championship fight to be held in Jersey City, New Jersey. Hopp recruited theaters and halls as listening locations that would charge admission fees to be used as charitable donations. He also contacted RCA's J. Andrew White, the acting president of the National Amateur Wireless Association (NAWA), an organization originally formed by American Marconi which had been inherited by RCA. White agreed to recruit the NAWA membership for volunteers to provide assistance at the listening sites, and also enlisted David Sarnoff for financial and technical support. RCA was authorized to set up a temporary longwave radio station, located in Hoboken a short distance from the match site, and operating under the call letters WJY. For the broadcast White and Sarnoff telephoned commentary from ringside, which was typed up and then read over the air by J. Owen Smith. The demonstration was a technical success, with a claimed audience of 300,000 listeners throughout the northeast.
  RCA quickly moved to expand its broadcasting activities. In the fall of 1921, it set up its first full-time broadcasting station, WDY, at the Roselle Park, New Jersey company plant. By 1923 RCA was operating three stations—WJZ (now WABC) and WJY in New York City, and WRC (now WTEM) in Washington, D.C. A restriction imposed by AT&T's interpretation of the patent cross-licensing agreements required that the RCA stations remain commercial free, and they were financed by profits from radio equipment sales.
