KABC 790 AM is a Los Angeles radio station, and a West Coast flagship station for the Citadel Broadcasting company. A pioneer of the talk radio format, the station went "all-talk" in 1960; it was one of the first stations ever to do so. This is one of many Disney/ABC Radio stations that has now merged with Citadel Broadcasting and remains an ABC affiliate to this day.

KABC first went on the air on April 14, 1925 as KVFV. On November 15, 1929 the station was sold to Earle C. Anthony, a local car dealer who already owned KFI-AM 640. He owned it until the early 1940s, when FCC rules changes meant no entity could own more than one radio station. While he owned the station, Anthony changed the call letters to reflect his initials, KECA. ABC bought the station in 1944, changing the call letters to the present KABC in 1954.

KABC has been the base of operation for many influential radio hosts, including early talk controversialists Joe Pyne and Louis Lomax, Ira Fistel, Michael Jackson, whose talk show attracted celebrities, politicians, and newsmakers of all types, pioneering radio psychologists Dr. Toni Grant and David Viscott, and more recent syndicated hosts including Dennis Prager (now with NewsTalk 870 KRLA and the Salem Radio Network), John and Ken (on KFI before their stint on KABC and now currently back on KFI) and Larry Elder. In the 1980s, Jackson, Grant and Viscott were also heard nationwide on ABC Radio's Talkradio network.

From 1974-97, it was also the station of the Los Angeles Dodgers and their hall-of-fame broadcaster Vin Scully. In 2008, the Dodgers Radio Network will return to KABC.

Though still a prominent Los Angeles station, during the past decade KABC's ratings share has declined; it now consistently ranks behind KFI, the other major talk station in Los Angeles.

In April 2007, administrators at Academia Semillas del Pueblo (ASDP) in the El Sereno community of North East Los Angeles filed a defamation lawsuit against KABC 790 AM and Doug McIntyre, claiming that the host of "McIntyre in the Morning" "targeted the school for destruction because the children were Latino, the teachers were Latino, the principal director was Latino," as stated in the lawsuit. The lawsuit alleges that school employees received death threats and that the school was the target of a bomb threat because of McIntyre's extensive on-air criticism of the school, in which he accused ASDP of espousing a racist and separatist Anti-American philosophy.

On November 6, 2007, Los Angeles Superior Court Judge Ralph W. Dau took the case under submission, and it is currently pending in his courtroom.
