of changes at KRTH accelerated the station's transition from oldies to a classic hits format. After Labor Day 2013, under new PD Rick Thomas, the station began to remove a portion of 1960s music, as it had appealed to a much older audience than was measurable by the ratings system. In addition, most early 1970s hits, as well as soul hits from the late 1960s through the mid-1970s, were eliminated; the playlist now focused on music from 1973 to 1989 (with only a few pre-1973 songs per day). With these changes, ratings rose substantially. In June 2014, CBS transferred Thomas to New York, with Chris Ebbott replacing him as program director. Ebbott was previously PD at CKFM-FM in Toronto. Also in 2014, Johnny Mann, whose singers have been responsible for KRTH's jingles over the years, died. Additionally, Charlie Van Dyke, who was KRTH's voiceover artist in recent years but more recently has also been the imaging voice of KABC-TV, was replaced as station voiceover with Joe Cipriano, the longtime voice of the Fox Television Network. In August 2015, "Shotgun" Tom Kelly left his afternoon drive position but remained with KRTH in an "ambassador" role, making public appearances and otherwise representing the station off-air. By early 2016, KRTH began adding songs from the 1990s into its playlist. 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 of 2018, KRTH no longer plays music from the 1960s through the mid-1970s, with its playlist shifting towards hits from the late 1970s through the early 2000s, with a heavy focus on the 1980s. However, the station's playlist is limited to avoid excessive overlap with sister station KCBS-FM, which airs an adult hits format. In addition to Rewind with Gary Bryan, KRTH also broadcasts America's Greatest Hits, hosted by Scott Shannon, and the 1980s and 1990s editions of Backtrax USA with Kid Kelly on the weekends. Bryan, Kelly, and Shannon are all former disc jockeys at WHTZ (Z100) in New York City. HD Radio KRTH broadcasts in HD Radio with two subchannels: KRTH-HD1 is a digital simulcast of the analog signal; it was launched in 2007. KRTH-HD2 airs an all-news format as a simulcast of KNX. KRTH-HD2 began broadcasting in 2010, originally featuring oldies from the 1955–1970 period, with an emphasis on the late 1960s and Motown
