Owned by Cumulus Media, KSFO's studios are located are on Battery Street in the SoMa portion of San Francisco's Financial District.

KSFO's transmitter site is in Fremont, near the Dumbarton Bridge, where its prominent towers are landmarks used by pilots as a waypoint in communications with local airports.

which provided some of the music, and a dramatic group known as the KGO Players, which performed weekly plays and short skits, often under the direction of Bay Area drama instructor Wilda Wilson Church.

On November 11, 1928, the Federal Radio Commission (FRC) implemented a major broadcasting station reallocation, based on its General Order 40.

In 1941, stations on 790, including WGY and KGO, were moved to 810 as part of the implementation of the North American Regional Broadcasting Agreement (NARBA).

KGO was instrumental in bringing the first exercise show to broadcasting, hosted by Jack LaLanne, a fitness instructor and gym operator in nearby Oakland.

LaLanne conducted his radio fitness show for many years on KGO, moving in the late 1950s to KGO-TV and a successful TV syndication career.

Among KGO's personalities during this period was future Radio Hall of Fame member J.P. McCarthy, the station's morning host in the early 1960s.

KGO started carrying Paul Harvey's twice-daily programs but also began to develop a strong local news staff that produced extended morning and afternoon newscasts.

The local talk show hosts included Les Crane, Owen Spann and Jim Eason, who often interviewed visiting celebrities in the KGO studios.

Local director-actor Jack Brooks hosted a Saturday-morning entertainment program until his sudden death in June 1984, after directing a production of Kismet for the Capuchino Community Theatre that featured Jim Eason as the poet Omar Khayyám.

Notable items up for auction have included a trip with Gene Burns on a private jet to various destinations, such as Las Vegas and Italy, for a gourmet dinner.

[18][19] This had resulted in the abrupt termination, on December 1, of most of the talk hosts (including Gene Burns, Gil Gross, John Rothmann, Ray Taliaferro, Len Tillem, and Dr. Bill Wattenburg).

The format change and termination of many popular talk show hosts sparked outrage among long-time listeners, many of whom called for sponsors to drop their advertising on the station.

[21] Ratings declined substantially following the change, with competitors KCBS and KQED-FM continuing to lead the market, and in December 2014, KGO reintroduced talk programming on weekdays.

[23] In January 2015, KGO announced they had hired Chicago/San Antonio radio personality Kevin "DreX" Buchar, best known for his successful morning show on Chicago's WKSC-FM, which ran for more than a decade, from 7PM to 10PM.

[26][27][28] Originally, long-time KGO host Ronn Owens announced that he would be moving to sister station KSFO in the afternoon slot beginning April 4.

[26] Owens left the station in 2018, and Armstrong & Getty moved to KSFO in 2020 to be replaced by Nikki Medoro, previously an afternoon news anchor.

[32] The station then began a stunt loop featuring songs and promotional announcements referring to betting, money, and winning.

The promotions stated that a new format, billed as "the most unique radio station in the Bay Area", would launch on October 10, assuring listeners that they "can bet on it".

KSFO is one of four AM stations owned by Cumulus Media in the San Francisco Bay Area, along with KZAC, 680 KNBR, and 1050 KTCT.
