announcers Jim Britt and Mel Allen. In 1951, WTAM originated an NBC Radio Network broadcast of the Cleveland Orchestra. NBC also expanded its broadcasting interests in Cleveland beyond AM radio: on October 31, 1948, NBC launched a sister television outlet, WNBK, on channel 4; a few weeks later, on December 6, 1948, WTAM-FM (105.7 FM) began broadcasting, simulcasting WTAM's programming. All three stations shared the same transmitter tower in Brecksville until WNBK moved to a new transmitter tower erected in Parma concurrent with a channel switch to channel 3 on April 25, 1954; as KYW and KYW-FM, both radio stations would move to the same Parma tower in February 1957. WTAM also aired Cleveland Browns games during the 1952, 1953, and 1955 seasons; Jim Graner provided color commentary during the 1955 season. KYW: The Westinghouse years In late 1955, NBC persuaded Westinghouse to trade its Philadelphia stations, KYW (1060 AM) and WPTZ-TV, in return for NBC's Cleveland properties and $3 million in cash compensation. NBC had long wanted to own a station in Philadelphia, the nation's third-largest market at the time. The swap went into effect on January 22, 1956. Westinghouse wanted to keep the historic KYW callsign, which had been Chicago's oldest radio facility before being transferred to Philadelphia on December 3, 1934. Therefore, on February 13, 1956, the Cleveland stations became KYW, KYW-FM and KYW-TV; and the Philadelphia stations became WRCV and WRCV-TV. The WTAM callsign was later picked up by WGLS in Atlanta, Georgia, and after that by WGCM-FM in Gulfport, Mississippi. In the early 1960s, under program director Ken Draper, KYW, known on-air as KY11, became a full service - Top 40 powerhouse with disc jockeys Jim Runyon (the "weeeellll" voice of the Chickenman series), Jim Stagg, Jay Lawrence, Jerry G (Jerry Ghan), and the morning duo of Harry Martin and Specs Howard. Its main Top 40 rival in the Cleveland market was "Color Channel 14" WHK, at 1420 AM. Almost immediately after the trade was finalized, Westinghouse complained to the Federal Communications Commission (FCC) and the Justice Department about NBC's coercion. It was discovered that Westinghouse only agreed to the trade when NBC made implications that it would pull its television programming from WPTZ and Westinghouse's other NBC affiliate, WBZ-TV in Boston. In 1964, after a protracted legal battle, the FCC ordered the swap of stations reversed without NBC realizing any profit on the deal.
