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

In 1928, [[William S. Paley]] assumed control of the network, which under his leadership focused on entertainment programming, news, and news affiliation. He quickly turned the failing company around, which was named Columbia Broadcasting System, Inc. ([[CBS]]) in 1929. By the end of 1938 there were 113 CBS outlets. Regional networks on CBS also existed in various parts of the country.<ref name="perry"/>

CBS later hired [[Edward R. Murrow]] who is credited with boosting ratings dramatically. Murrow and CBS covered the war in Europe while [[Adolf Hitler]] was in power. NBC and ABC withdrew from the war for safety reasons. As a result of taking the risk, CBS's ratings skyrocketed.<ref>Edwards, B. (2004). Edward R. Murrow and the Birth of Broadcast Journalism.
