On July 14, 1994, after the E. W. Scripps Company signed an affiliation deal with ABC that renewed the network's affiliations with its affiliates in Cleveland and Detroit (which were both heavily targeted by CBS to replace two stations that were slated to switch to Fox) and caused three other stations to switch to the network, Westinghouse Broadcasting (Group W) signed a long-term deal with CBS, in which three Westinghouse-owned stations (one that was aligned with ABC and two that also were aligned with NBC) would become CBS affiliates, joining two other stations owned by the company that were already affiliated with that network. (Westinghouse would later acquire CBS one year later in August 1995, turning all of the Group W radio and television stations into CBS owned-and-operated television and radio stations.) One of the stations involved in the affiliation agreement was Philadelphia's longtime NBC affiliate, KYW-TV. CBS decided to sell off its longtime O&O in that market, WCAU-TV, but later discovered that an outright sale of that station would have forced it to pay taxes on the proceeds from the deal. This led to a deal that was struck on November 21, 1994, between CBS and NBC, in which CBS sold the channel 6 transmitter facility and license to NBC as compensation for the loss of KYW-TV and Westinghouse's other NBC affiliate, WBZ-TV in Boston. In return, CBS received the stronger channel 4 transmitter facility, license, and cash as compensation for the loss of WCAU (KCNC-TV in Denver and KUTV in Salt Lake City was acquired by NBC earlier that year were both purchased by, and ended up switching to CBS as a result of this deal).
