In 1996 BBC sold the FM station and AM simulcast sister station (KDFC 1220 AM) to Evergreen Media, who in turn, in 1997, sold the FM station to Bonneville Broadcasting and the AM station to Douglas Broadcasting.
New station management transitioned KDFC's programming to a more mass-appeal approach, which boosted ratings significantly, though the station was occasionally criticized for what was characterized as a "top 40 of classical music" approach.
In this light, the policy of then-owner Bonneville did not allow advertising for liquor, lotteries, or casinos.
In March 2007, KDFC pulled a commercial for Chris Hedges' book American Fascists: The Christian Right and the War on America.
The ad was tailored to play only in the Bay Area, to promote local appearances by the author.
Bill Lueth, KDFC’s operations and program director, insisted that pulling the ad was not a free-speech issue.
The station broadcasts a classical music format, simulcasting KOSC in San Francisco.
The University of Southern California also acquired the 89.9 FM frequency in Angwin, California and its two translator signals in Eureka and Lakeport.That station, on 89.9 MHz, will be assigned the call letters KDFC, according to an E-mail from KDFC president Bill Lueth, who added, "We now actually own a signal." KDFC returned to the South San Francisco Bay area, with the addition of 104.9 on Friday, June 15, 2012.
