was XHIS-FM. It began broadcasting more than three years before receiving its concession in November 1973. It was owned by Víctor Díaz, the founder of Califórmula Broadcasting, which would come to own and operate numerous stations in the San Diego-Tijuana
radio market.

station known as "HERS Radio", signed on in December. A third station,
XHQS-FM 95.7 "OURS", was also planned. Aside from the music, HIS Radio featured parodies of commercials and a satirical radio novel, the O.B. Ranger. The operation was run by Larry Shushan, a former owner of
KPRI FM radio and one of the builders of
KAAR, San Diego's first UHF television station.
XHIS and XHERS broadcast from a new facility in Tijuana with custom-built 100,000–watt transmitters, throwing maximum power at San Diego. These were the first
border blasters on FM. Programming originated from Time Sales's studios and sales offices at the Royal Inn at the Wharf and was transported by cassette to the transmitter, as the
Brinkley Act prevented a live hookup from being used. Within six months, Time Sales had two of the top three stations in San Diego.
FCC investigation
By 1973, however, the tides had turned for Time Sales. San Diego broadcasters complained of disloyal competition across the border that didn't have to play by the

XHITZ-FM
Two years later, Díaz bought back the cluster of XHIS and XHERS, instituting new call signs and formats on both. That year, XHIS became XHITZ-FM and changed to an

format under contract to San Diego Radio Company. However, in 1984, the station stumbled in an ownership dispute. A bitter battle between San Diego Radio Company and Califórmula led to the abrupt end of the album rock format as the latter took control of the station.
Díaz cited continued low ratings, but the straw that broke the camel's back was a humorous news report read on the station that stated a German anthropologist had discovered a tribe of "mole people" living in the sewers of Mexico City. When the report was read in late June, it caught the attention of
Mexican authorities, who were outraged over the secondhand account they had heard, which implied that Mexicans were so poor they lived in sewers.
In 1986, Díaz sold the American marketing rights for XHITZ again, this time to Broadcasting, Marketing and Management, Ltd. BMM ceased operation of the station on June 30, 1988 as it assigned the rights to another company, Consolidated Radio Sales, which was also bankrupt. The result was that Díaz and the head of Consolidated Radio Sales, Jack McCoy, clashed. In mid-July, McCoy fired all the employees in the U.S. and had all the locks changed, with several employees instead showing up to work in Tijuana. Later that day, however, a bankruptcy judge ruled that Díaz owned the U.S. operation of the stations.
In 1989, XHITZ flipped from

-leaning Top 40 format, under Program Director Rick Thomas. "Z90" competed against
Q106, which was the powerhouse Top 40 station in the market. With Z90's debut, however, it took only a few books for XHITZ to beat Q106. And thanks to its success, it also forced the market's only

format. It wasn't until September 1996 that XHITZ had another direct competitor, 93.3
KHTS, which had a Dance lean, much like XHITZ. Even though XHITZ served as the official call letters, it was marketed unofficially as "XHTZ" due to the fact that most TV and radio call signs carry four letters.
By August 1998, XHITZ moved away from its Dance approach to begin focusing more on

R&B. The station also rebranded as "Jammin' Z90" before reverting to "Z90.3". In 2002, Califórmula was winding down most of its operations as Díaz retired and then died. The U.S. operating rights were sold to Clear Channel Communications (forerunner of today's

) and the concession was transferred to a new Mexican concern, Comunicación XERSA. XHITZ remained a hip-hop leader until 2004, when
XHMORE-FM flipped to a hip hop-leaning
Rhythmic Top 40. These two stations competed for listeners until late 2009, when XHMORE changed formats. Shortly after this, XHITZ shifted back to its more dance-leaning direction. Despite being the market's only Rhythmic Top 40, XHITZ continued to share much of the same music as KHTS-FM and
KEGY, all of which were rhythmic-leaning Top 40/CHRs. On April 2, 2012, XHITZ rebranded from "Z90.3" to "Jammin' Z90."
In mid-2014, XHITZ rebranded back to "Z90." Today, the station airs a mainstream Top 40/CHR format, resulting in both
Nielsen BDS and
Mediabase moving XHITZ from the Rhythmic to Mainstream reporting panels in February 2015.

ruling forced Clear Channel to divest the operating rights to its Mexican stations in order to remain under FCC ownership caps.
On July 25, 2005, Clear Channel transferred the programming and local marketing arrangements of XHITZ, along with XETRA-FM and XHRM-FM, to Finest City Broadcasting. Finest City was a new company under the direction of former Clear Channel/San Diego VP/Market Manager Mike Glickenhaus. Finest City took over operations on December 1, 2005.
Local Media San Diego
In 2009, these programming and marketing rights were sold to Broadcast Corporation of the Americas after Finest City defaulted on assets that resulted in its bankruptcy. In 2010, BCA spun off XHITZ, XETRA and XHRM to Local Media San Diego after a change in management.
On October 6, 2015, Midwest Television, the owner of
KFMB-TV channel 8,
KFMB 760 AM and
KFMB-FM 100.7, announced that it had entered into a joint operating agreement with Local Media San Diego LLC. They formed an entity known as "SDLocal" to manage its cluster of radio stations. The intent of this agreement was to "
reserve thelocal ownership and operation of San Diego's top-rated radio stations".
The agreement ended at the end of 2016.
Local Media San Diego eventually acquired KFMB and KFMB-FM outright from
Tegna, Inc. on March 17, 2020. KFMB 760 AM was divested to iHeartMedia.
Tegna had purchased Midwest Television's stations in 2018.
Local Media San Diego held onto KFMB-FM, which switched its call letters to KFBG; LMSD would later sell KFBG to
Lotus Communications in 2025.
