In 1927 Westinghouse aligned its four radio stations ( KYW, KDKA in Pittsburgh, WBZ in Boston, and WBZA in Springfield, Massachusetts ) with the NBC Blue Network, which originated from former sister station WJZ ( the present-day WABC ) in New York City.

WBZ / WBZA, KDKA and KYW became affiliates of NBC's Red Network while WOWO, which had a secondary affiliation with the Blue Network, fell back on its primary relationship with CBS.

Westinghouse built FM sister stations for WBZ / WBZA, KDKA, KYW, KEX and WOWO, all of which were on the air by the end of the decade.

But in New York, Los Angeles and Philadelphia, CBS had to compete with Westinghouse-owned stations ( WINS, KFWB and KYW, respectively ) which had adopted all-news programming before the CBS stations did.

Mendte occasionally writes for the print version of the magazine, for which he wrote an article on his life after he was let go by KYW.

Channel 4 nearly lost its NBC affiliation in 1955 when Westinghouse balked at NBC's initial offer to trade sister stations KYW radio and WPTZ television ( now KYW-TV ) in Philadelphia in exchange for the network's radio and television combination in Cleveland, Ohio.

KYW acquired a television counterpart when Westinghouse bought WPTZ ( channel 3 ) -- the nation's third commercial television station and NBC's second television affiliate -- in 1953.

In June 1955, Westinghouse agreed to trade KYW and WPTZ to NBC in exchange for the network's properties in Cleveland, WNBK television and WTAM-AM-FM.

NBC had to seek a waiver for the swap since KYW and NBC Radio's New York City flagship, WRCA ( now sister station WFAN ) were both clear channel stations ; at the time, the Federal Communications Commission ( FCC ) normally did not allow common ownership of clear-channel stations with overlapping nighttime coverage.

NBC took over the Philadelphia stations, rechristening 1060 AM as WRCV ( for the RCA-Victor record label ), and Westinghouse moved the KYW call letters to Cleveland.
