KABC (790 AM) is a Los Angeles radio station, and a West Coast flagship station for the Cumulus Media company. A pioneer of the talk radio format, the station went "all-talk" in September 1960, the second radio station to do so, a few months after St. Louis' KMOX. KABC is owned by Cumulus Media, but despite different owners, 790 KABC, KABC-TV and KSPN maintains a strong partnership (as KABC-TV is the local ABC owned-and-operated station). The station's studios and transmitter are both co-located on La Cienega Boulevard in the West Adams district of Los Angeles.
