Programming format changes
Liberal talk – 2005
In the Fall of 2005, following different music and other programming over the years, KOMY began airing a progressive talk format, becoming an Air America Radio affiliate. Thus, KOMY was considered the "liberal version" of sister-station KSCO, which primarily aired conservative programming. On June 28, 2006, KOMY dropped The Majority Report with Janeane Garofalo. According to station owner Michael Zwerling, this decision was because the show had failed to gain a single advertiser during the year that it was on the station. After three consecutive Arbitron zero ratings periods between January and November in 2006, KOMY would change formats in January 2007.
On Thursday, January 25, 2007, at 10 a.m., KOMY 1340 dropped the progressive talk format and went to a 1950s/1960s 'oldies' format. For nearly two months, beginning on January 25, the original Oldies programming broadcast on the air by KOMY was fed via the Bay Area Radio Museum's Internet audio server, with custom "KOMY 1340" PAMS jingles that were freshly recorded for the station. On March 20, 2007, KOMY began 'stunting,' using construction sound effects and promoting roughly every four minutes that KOMY would return with a better signal and programming. Two days later, KOMY adopted the Jones Satellite Networks' oldies format. This format change was a return to the roots of KOMY 1340, a popular Top-40 station back in the 1960s, when it was very briefly the home of radio legend Robert W. Morgan early in his career.
Adult standards music – 2009
In the first week of April 2009, KOMY management decided that they were no longer satisfied with Jones'oldies format, which had changed as a result of recent radio network mergers. For no more than a few days, KOMY was basically simulcasting sister station KSCO's talk programming. There was now no Oldies format station in the Monterey Bay Area AM market. Then KIDD seized on this opportunity and without notice immediately changed its format from an Adult Standards/Big Band format to an Oldies format as Oldies 630.Magic 63's listeners were quickly in an uproar over the loss of the only Standards station in the market. Recognizing a loyal listener demographic, KOMY quickly followed KIDD's change and immediately adopted a hybrid Adult Standards format. The music and formatics adopted by KOMY, including the Magic & Memories imaging, were put in place by David Jackson of the , with voice imaging by KSCO/KOMY production director Bill Graff.
Current programming – 2017
Currently, KOMY during the weekdays airs programs from the Genesis Communications Network including The Alex Jones show. in addition, the station originates the health show, "Dead Doctors Don't Lie" with Dr. Joel Wallach. On weekends, KOMY simulcasts sister station KSCO's programming. Like KSCO, KOMY relies on commissions from the sale of Wallach's nutritional supplements as its primary source of revenue.
