following the completion of the cbs takeover, the former westinghouse broadcasting operations took on the cbs name and identity, though the "group w" name survived until the end of the 1990s as a holding company within the merged entity's structure. the westinghouse-cbs merger resulted in several longtime rivals on the radio dials of new york city, los angeles, chicago, and philadelphia becoming sister stations. excluding wmaq (shut down in 2000 to allow all-sports wscr to move to its old dial position) and kfwb (placed in a holding trust as a consequence of cbs's purchase of kcal-tv; the trust divested the station in 2016), all of the former group w radio stations were part of cbs radio until its merger with entercom on november 17, 2017, with the merged entity taking entercom's name; following the merger, one of the former group w stations, wbz, was spun off to iheartmedia. cbs had previously announced in 2016 that it had been looking to leave the radio business.
