KFMB-FM is a commercial radio station located in San Diego, California, broadcasting on 100.7 FM. KFMB-FM airs a hot adult contemporary music format with an alternative rock slant, branded as "Jack FM". It shares studios with its sister television station KFMB-TV (channel 8) and radio station 760 AM KFMB in the Kearny Mesa section of San Diego. KFMB-FM's transmitter is in La Jolla.
What eventually became KFMB FM began testing in 1950 from the North Park Theater on Adams Avenue. It finally signed on for commercial operation on 100.7 MHz in 1959 airing a Beautiful Music format. In the late 1960's the format was called "Music Only For a Woman." Station Manager Ed Peters bought the rights to syndicate the format. Soon after, Peters left and started his own company known as "Peters Productions" which syndicated the format on reel-to-reel tape to over 100 stations during the 1960s and 1970s, changing the name of the format to "Music Just For The Two Of Us."
San Diego in the early 1970s had three "beautiful music" stations and was about to gain a fourth, so KFMB AM program director Bobby Rich and station manager Paul Palmer concocted a super high energy Top 40 format to challenge market leader 1170 AM KCBQ. Rich wanted to change the call letters to something with "Q" in them to become "the FM Q" but the owners refused to break up the KFMB AM/FM/TV matched set of calls. Although 100.7 is closer to 101 than 100, 101.5 KGB-FM had already established itself as 101KGB, so KFMB-FM became "B-100" in March 1975 with the slogan "Better Boogie", eventually knocking off longtime AM Top 40 powerhouse KCBQ in the Fall 1977 Arbitron ratings. B-100 was the first major market FM Top 40 station to achieve overall #1 Arbitron ratings for all listeners. The station's on air staff during its first two years included Phil Flowers, Rich Brother Robbin, Rocket Man, Jimi Fox, Willie B. Goode, Rob Landree, Dave Conley, Billy Martin, Glen McCartney, Shotgun Tom Kelly, Gene Knight, Danny Wilde, Gary Kelley, Billy Pearl, Beaver Cleaver (aka Ken Levine), Jimmy Rogers, Chris Lance, Terri Lynne, Uncle Fred, and Dr. Boogie (aka Bobby Rich). Several from this group left to create Ten Q (KTNQ 1020 AM) in Los Angeles after the first year.
B-100 had major success in the 1980s, reinventing itself as one of the nation's first "hot" adult contemporary stations, melding top 40 hits, minus some teen-oriented songs, with an adult delivery by its high-profile air staff, including "The B-Morning Zoo with The Rich Brothers" featuring Bobby Rich (now mornings at Mix 96, Tucson), Scott Kenyon (deceased 2011), Pat Gaffey, and Frank Anthony (now at 105.7 Max FM in San Diego), along with Gary Kelley, Gene Knight, Danny Romero (now a weatherman with ABC7, Los Angeles), Ellen Thomas (now Ellen K at KIIS, Los Angeles) and John Fox (now general manager of the first radio station in Southern California owned by a Native American tribe, Rez Radio 91.3, KOPA in Pala).

Jeff and Jer became the morning show at B-100 in the late 1980s. On May 16, 1994, B-100 ended its longtime Hot AC format. After a few weeks of stunting, the station flipped to Adult contemporary music and adopted the moniker "Star 100.7" in June. Star 100.7 aired the Bob and Sheri syndicated morning drive show in the early morning hours. "Star 100.7" continued until April 6, 2005, at 9:55 AM, when the station began stunting with a 5-minute ticking clock and a mysterious voice saying "closer...closer", which ended with an alarm going off and a female announcer saying "Bye Star". Jack FM and its adult hits format was then introduced with R.E.M.'s "It's The End of the World As We Know It (And I Feel Fine)." Local hosts Jeff and Jer left KFMB-FM in August 2005 and moved across town to KMYI 94.1 FM, now known as "Star 94.1". KFMB-FM is now home to the former long-time KGB-FM morning show, "Dave, Shelley and Chainsaw," often abbreviated to "The DSC." In September 2013, KFMB-FM instituted a paywall for its online webstream, which only allows listeners in the San Diego area to hear the audio.
In 2014, the station's sound evolved from the Adult Hits format heard on other "Jack-FM" stations around the country, including 93.1 KCBS-FM in nearby Los Angeles. The station added more current and recent hits, and deleted most songs recorded before 2000, other than those recorded by established Modern Rock artists such as Green Day, INXS and U2. KFMB-FM continues to call itself Jack-FM and uses the slogan Playing what we want. But in April 2014, Mediabase added KFMB-FM to its Adult Top 40 panel, reflecting its shift from Adult Hits to a Modern Rock-leaning Hot AC format.
Morning shows on Jack: Monique and the Man; The DSC
The station conducted a nationwide search for a morning show in September 2005, with a $1,000,000 five-year contract. The winner was the Monique and the Man morning show featuring Hispanic comedian Monique Marvez and former Star 100.7 DJs Greg and Sara. Greg is the 'Man' and Sara is a co-host. The show started on January 23, 2006 and ended in 2009. As with many stations calling themselves "Jack-FM," there was no morning show until Dave, Shelley and Chainsaw took over on August 2, 2010. The show, previously on KGB-FM, helped boost KFMB-FM's morning ratings.
