The station has programmed minor variations of adult contemporary music with the KEZR call letters since 1973.
This popular San Jose radio station has held many mixers and events with several famous artists including Sara Bareilles, Jason Mraz, and Augustana.
Before it was purchased by NextMedia, the station was briefly owned by CBS Radio, who moved the station from San Jose to San Francisco. Prior to that, it was owned for a long period by the Levitz family. During this period, particularly the 1990s, KEZR was a dominant force in Bay Area radio, regularly topping the Arbitron ratings.
