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. NBC regained control of the Cleveland stations on June 19, 1965 and changed their call letters to WKYC, WKYC-FM and WKYC-TV, which kept the popular "KY" slogan and identity Westinghouse brought into Cleveland.
