The transmitter is off West Martin Luther King Boulevard in the Crenshaw District, shared with KWKW (1330 AM) and KFOX (1650 AM).

In afternoon drive time, John Phillips hosts a three-hour show, followed by Frank Mottek and Randy Wang.

Syndicated programs include Armstrong & Getty, The Dan Bongino Show, America in the Morning and Red Eye Radio.

On November 15, 1929, KPLA was sold to Earle C. Anthony, a Packard automobile dealer and owner of rival radio station KFI.

In 1941, KECA moved one step up the dial to 790 kHz as part of the North American Regional Broadcasting Agreement (NARBA), which shifted the frequencies of many radio stations.

In 1944, new Federal Communications Commission (FCC) rules went into effect prohibiting any person or company from owning more than one radio station in the same media market.

[9] Along with co-owned KGO in San Francisco, ABC built a nationally syndicated radio network around the personalities of the two top-rated West Coast talk outlets.

The ABC TalkRadio Network featured KABC personalities Michael Jackson who hosted middays, psychologist Dr. Toni Grant in afternoons, and Ira Fistel and Ray Briem at night.

The network was heard on scores of radio stations around the country, including co-owned WABC in New York City.

The station has also served as the home of psychiatrist David Viscott and early talk radio pioneers Joe Pyne and Louis Lomax.

Also fired were imaging voice Howard Hoffman and news director/morning newscaster Mark Austin Thomas, who joined KNX.

[14] Jillian Barberie, Drew Pinsky, Leeann Tweeden, and Peter Tilden were all dismissed at the end of 2019 as KABC changed to an all-syndicated talk lineup; John Phillips, Randy Wang, and Larry O'Connor (from WMAL-FM in Washington, D.C.) were the lone local hosts retained.

In August 2014, KABC became the flagship radio station of the Los Angeles Kings hockey team; that arrangement ended in 2018, with the games switching to KEIB.

[8] On May 2, 2019, the University of Southern California announced play-by-play coverage of its football and men's basketball teams would return to KABC.
