In 1994, sister station WJZ-TV in Baltimore lost its affiliation with ABC after that network announced a deal with the E. W. Scripps Company to switch three of Scripps' television stations—including its Baltimore outlet, WMAR-TV—to ABC as a condition of retaining its network affiliations with WEWS-TV in Cleveland and WXYZ-TV in Detroit; CBS intended to affiliate with those two stations, as it was about to lose its longtime affiliates in Cleveland and Detroit to Fox due to a deal with New World Communications. Westinghouse felt betrayed by ABC's decision, and as a safeguard began shopping for affiliation deals for the entire Group W television unit. Group W eventually struck an agreement to switch WBZ-TV, KYW-TV and WJZ-TV to CBS (Westinghouse's two other stations, KDKA-TV in Pittsburgh and KPIX in San Francisco were already CBS affiliates). The Boston market's third network affiliation switch took place on January 2, 1995. After a 47-year relationship with NBC, channel 4 became the third station in Boston to align with CBS. The network had originally affiliated with WNAC-TV in 1948, then moved to channel 5 (the original WHDH-TV) in 1961; it then returned to WNAC-TV (predecessor to the current WHDH) in 1972 and remained on channel 7 until the switch.
