KFOG is an FM radio station in San Francisco, California, broadcasting simultaneously on 104.5 and sister station KFFG 97.7 FM MHz. The 97.7 transmitter is located near Cupertino, California, and serves listeners in the South Bay, San Jose, California, and Silicon Valley who are unable to get a clear signal from the 104.5 transmitter on Sutro Tower in San Francisco.
The stations' formats are classified as adult album alternative or Triple-A, an eclectic variety of blues, reggae, folk, pop, and rock music from the mid-1960s to the present, which they call "World Class Rock." Both stations are owned by Cumulus Media.
The KFOG call letters have been around for decades, and were used when 104.5 played beautiful music. During midday on September 16, 1982, with Stray Cats' "Rock This Town" and Dave Morey at the mic, they dropped the easy listening format for a unique blend of album-oriented rock (AOR). They called it "Timeless Rock", and it featured a wide range of music, from the psychedelic sounds of the Grateful Dead and Jefferson Airplane to newer artists such as Prince, Eurythmics and the Thompson Twins. They avoided more commercial bands such as Loverboy, which were widely played on many other AOR stations at the time. KFOG's specialty programming included the nightly "Psychedelic Psupper" and the "Sunday Night Idiot Show", which featured 1950s oldies. KFOG was heavily inspired by San Francisco's freeform rock radio heritage, dating back to KSAN.
When KFOG went on the air, the Bay Area was deluged with AOR stations. KMEL was the established, tightly-formatted AOR station that had been playing rock since 1977. KRQR was the hard rocker in town. And KQAK was the newcomer, with a friendly, loosely programmed, personality-driven alternative rock/new wave format. There were also two other rock stations in the South Bay - KSJO and KOME. And one San Francisco rocker, KSFX dropped out of the format in May of that year to switch to news/talk. Of all six Bay Area rock stations that were on the air in late 1982, KFOG is the only one that remains to this day.
KFOG has developed a reputation for being devoted to their community of listeners, whom they affectionately call "Fogheads." A prime example is the weekday morning show from 6 to 10 Pacific Standard time. Prize giveaways (usually concert tickets) are routine, and the guests (including San Francisco Mayor Gavin Newsom, who drops by about once a month) candidly field questions from callers and e-mails. The station also gives registered Fogheads first crack at tickets to private concerts and exclusive events.
The station also holds a popular outdoor concert, KFOG KaBoom, at San Francisco's Piers 30 and 32 each May. This is followed by a nighttime fireworks show synchronized to a soundtrack. The extravagant fireworks display draws over 350,000 people. The lineup for the 2009 edition included Los Lonely Boys, Susan Tedeschi, and Chuck Prophet.
Many of the concerts KFOG sponsors are also recorded for KFOG's "Live from the Archives", a massive library of live performances that gets tapped once a year for a limited-edition CD called KFOG Live From the Archives. No more than 35,000 copies of each volume are pressed, and all of the proceeds are donated to Bay Area Food Banks. Volume 16 was released in November 2009.
KFOG also has a history of playing various songs at the same time each week. On Friday afternoons at 5:00 PM PST, the station always broadcasts the song "Smoke Two Joints", playing a version by either The Toyes or Sublime.
In 2002 KFOG was the first in the nation to put its music on iTunes & on HD Radio. KFOG also streams its programming live over the Internet worldwide at www.kfog.com. There is a foghorn sound effect heard from time to time.
