Eventually, the newer songs and pop songs were phased out in favor of mostly classic rock and classic alternative. KCBS-FM is the longest-serving of all of CBS' Jack stations. CBS also introduced the Jack FM format in New York, Chicago, Dallas, Minneapolis, Seattle and Baltimore. Though the station has no DJs, KCBS-FM will occasionally respond to current events, such as playing all Michael Jackson songs following his death, or spinning a celebratory tune or two following a local sports victory (especially with the Rams). The "voice" of Jack FM is a real person named Howard Cogan. His quips which are heard between songs are created by a team of writers. As Jack became popular, Cogan moved to Los Angeles to record his comments more easily. He is also the voice-over artist for other "Jack FM" stations around the country. In October 2008, CBS Radio chose not to move the KCBS-FM call letters to its sister station at 106.9 FM in San Francisco, after that station flipped from classic hits to an all-news simulcast of KCBS. That station remains KFRC-FM, heritage calls in themselves. Entercom and Audacy On February 2, 2017, CBS Radio announced it would merge with Entercom. The merger was approved on November 9, 2017, and was consummated on November 17. As part of the agreement with CBS, Entercom was given the rights to use the brand and trademarks for KCBS-FM along with sister stations WCBS-AM and WCBS-FM in New York City, KCBS-AM in San Francisco for a 20 year period after which Entercom (or succeeding entity) will be required to relinquish using those call-letters. As part of the merger, the FM radio rights to the Los Angeles Rams of the National Football League were moved to KCBS-FM from KSWD, which was sold off as part of the deal when it flipped to contemporary Christian format as KKLQ on November 16, 2017. The Rams broadcasts were FM only, and regular programming was exclusive to the Audacy app during game broadcasts, including in Los Angeles. On March 30, 2021, Entercom rebranded to the corporate name "Audacy". KCBS-FM programming is found on the Audacy.com website and app. KCBS-FM HD In addition to the main Jack FM format on HD1, KCBS-FM-HD2 simulcasts KFRG, its co-owned country music station in San Bernardino. Before KLSX switched from talk to CHR in 2009, 93.1 HD2 carried a CHR format with the “AMP Radio” branding. Former
