The NBC Red Network is a defunct American radio network. Launched in 1926, it, along with the NBC Blue Network, were the two original radio networks of the National Broadcasting Company, and the first two commercial radio networks in the United States. CBS Radio was established a year later. In 1943, NBC was required to divest itself of its Blue Network, which would eventually become the American Broadcasting Company (ABC). The Red Network continued as the NBC Radio Network. The NBC Radio Network itself no longer exists under its original configuration, having been spun off and gradually dissolved into eventual corporate parent Westwood One. ==Creation== In 1923, the Radio Corporation of America (RCA) acquired control of WJZ in Newark, New Jersey, from Westinghouse, and moved the station to New York City〔(【引用サイトリンク】title=Why Did WABC Have Such a Great Signal? )〕 The same year, RCA obtained a license for station WRC in Washington, D.C., and attempted to transmit audio between WJZ and WRC via low-quality telegraph lines, in an attempt to make a network comparable to that operated by American Telephone & Telegraph. AT&T had created its own network in 1922, with WEAF in New York serving the research and development function for Western Electric's research and development of radio transmitters and antennas, as well as AT&T's long-distance and local Bell technologies for transmitting voice- and music-grade audio over short and long distances, via both wireless and wired methods. WEAF's regular schedule of a variety of programs, and its selling of commercial sponsorships, had been a success, and what was known at first as "chain broadcasting" became a network that linked WJAR in Providence, Rhode Island and AT&T's WCAP in Washington. Since AT&T refused access of its high-quality phone lines to competitors, RCA's New York-Washington operated with uninsulated telegraph lines which were incapable of good audio transmission quality and very susceptible to both atmospheric and man-made electrical interference. In 1926, however, the management of AT&T concluded that operating a radio network was incompatible with its operation of America's telephone and telegraph service, and sold WEAF and WCAP to RCA for approximately one million dollars. As part of the purchase, RCA also gained the rights to rent AT&T's phone lines for network transmission, and the technology for operating a quality radio network. On September 13, 1926, RCA chairman of the board Owen D. Young and president James G. Harbord announced the formation of the National Broadcasting Company, Inc.,〔"Form National Company For Broadcasting," ''The Syracuse Herald'', September 13, 1926, p. 6〕 to begin broadcasting upon RCA's acquisition of WEAF on November 15. "The purpose of the National Broadcasting Company will be to provide the best programs available for broadcasting in the United States. ... It is hoped that arrangements may be made so that every event of national importance may be broadcast widely throughout the United States," announced M.H. Aylesworth, the first president of NBC, in the press release.〔Id.〕 Although RCA was identified as the creator of the network, NBC was actually owned 50% by RCA, 30% by General Electric, and 20% by Westinghouse. The network officially was launched at 8 p.m. ET on Monday, November 15, 1926. "The most pretentious broadcasting program ever presented, featuring among others, world famed stars never before heard on the air, will mark the Introduction of the National Broadcasting Company to the public Monday night," the press noted, with "a four hour radio performance by noted stars of opera, stage and concert hall". Carl Schlagel of the Metropolitan Opera opened the inaugural broadcast, which also featured Will Rogers and Mary Garden.〔"Radio-- Notes and Programs for the Day," The North Adams Transcript (North Adams, Mass.), November 15, 1926, p.7〕 The broadcast was made simultaneously on WEAF and WJZ. Some of NBC's programming was broadcast that evening on WEEI (Boston) WLIT (Philadelphia), WRC (Washington), WDAF (Kansas City), and WWJ (Detroit).,〔 noted by the different background color.
