Broadcast network

The network featured a variety of regularly scheduled programs which included sponsorships (at the time not called advertising but "toll broadcasting").

[3] AT&T eventually decided to concentrate on its most profitable business, telephones, and in 1926 sold its broadcasting interests to the Radio Corporation of America (RCA).

[3] After acquiring WEAF and AT&T's network assets in 1926, RCA created the National Broadcasting Company (NBC) and reorganized the WEAF chain (with WGR, WTIC, WTAG, WEEI, WJAR, WZAN, WFI-WLIT, WCAE, WRC, WTAM, WSAI, WWJ, WGN, WOC, KSD, WDAF, WCCO) as the NBC Red network and the WJZ chain as the NBC Blue network (with WBZ, WBZA, KYW, KDKA).

In 1941, the Federal Communications Commission's (FCC) Report on Chain Broadcasting[4] reviewed the alleged monopolistic practices of the radio networks.

[5][6] As a consequence, NBC Blue was sold to Edward Noble who later named it the American Broadcasting Company (ABC).

[2] In 1927, United Independent Broadcasters, Inc., supported by the Columbia Phonograph Record Company, started a new network of 16 stations (WOR New York, WFBL Syracuse, WMAK Buffalo-Lockport, WNAC Boston, WEAN Providence, WCAU Philadelphia, WJAS Pittsburgh, WCAO Baltimore, WADC Akron, WAIU Columbus, WKRC Cincinnati, WGHP Detroit, WOWO Fort Wayne, WMAQ Chicago, KMOX St. Louis, KOIL Council Bluffs) named the Columbia Phonographic Broadcasting System.

[7] In 1945, the NBC Blue network was sold to Edward John Noble, who later renamed it American Broadcasting Company (ABC).

In 1929, a group of four radio stations in the major markets of New York City, Chicago, Cincinnati, and Detroit organized into a loose confederation known as the Quality Network.

Radio news network launched on January 1, 2015, and operated by Westwood One through its parent company Cumulus Media.

The first regularly scheduled coast-to-coast network program produced by CN Radio was broadcast on 27 December 1928.
