Group W felt betrayed by ABC after so many years of loyalty, as channel 13 had been ABC's longest-tenured affiliate at the time (a distinction that now belongs to WJLA-TV). As a safeguard, it began to shop for an affiliation deal of its own. One month later, Westinghouse agreed to a long-term affiliation contract with CBS, resulting in WJZ-TV and its sister stations in Philadelphia and Boston switching to CBS (Westinghouse's two other television stations, in Pittsburgh and San Francisco, were already CBS affiliates). The affiliation switch, the second in Baltimore television history, occurred early on the morning of January 2, 1995. The last ABC prime time program to air on channel 13 was the made-for-TV movie "A Dangerous Affair", which was broadcast at 9:00 p.m. Eastern Time on January 1, and the final overall ABC program to air on channel 13 was the January 2 edition of "ABC World News Now". As a result, channel 13 became the third station in Baltimore to affiliate with CBS. The network had originally affiliated with WMAR-TV in 1948 before moving to WBAL-TV in 1981. Westinghouse then bought CBS on November 24, 1995, making WJZ-TV a CBS owned-and-operated station. Notably, this marked the first time that CBS had wholly owned a station in the Baltimore/Washington corridor; it had been minority owner of WTOP-TV in Washington (now WUSA) from 1950 to 1955.
