The station originally signed on the air in 1957 from the Pasadena City College campus as KPCS; the call sign stood for Pasadena City Schools, which operated the college before the advent of the state-controlled Pasadena Area Community College District. It used the former KWKW-FM 250-watt transmitter and studio equipment, and a small antenna on the roof of the campus administration building that provided limited coverage. The station was operated by, and for, students who were studying broadcasting at the college. KPCS changed to KPCC on December 1, 1979.[3] KPCC rebranded to LAist on February 7, 2023.

Formerly, the station broadcast from a transmitter in Orange County, later from Downtown Los Angeles (at the Frank Stanton Studios), and on the PCC campus.

KPCC's Mohn Broadcast Center in June 2011

The station originally broadcast from the campus of Pasadena City College in Pasadena. KPCC decided to invest in a $24.5 million modern facility. In February 2010, the station moved to a 35,000-square-foot (3,300 m2) converted office building on Raymond Avenue in Pasadena named the Mohn Broadcast Center and Crawford Family Forum.

The station is operated by Southern California Public Radio, a group owned by American Public Media Group (the parent organization of Minnesota Public Radio). However the license remains in the hands of Pasadena City College (PCC); the station is usually identified as a "public service of Pasadena City College" at the top of each hour. Since the APM takeover, PCC student participation has been reduced to internships supported by American Public Media.[citation needed]

PCC's contract with American Public Media permits either side to terminate the arrangement after giving sufficient notice, APM with six months notice and PCC with five years notice after 2015 (effectively making it a 20-year contract with an unlimited option to renew). PCC gets on air recognition and funding for a broadcast internship program (along with the traditional responsibility of maintaining FCC-related issues as the licensee), while APM controls the station and all the pledges, grants, and corporate underwriting revenues.

SCPR acquired the rights to relaunch the LAist brand, which was formerly under the Gothamist blog. On January 31, 2023, Southern California Public Radio announced KPCC would move away from its call letters and adopt the "LAist" brand name across all its platforms, including the radio station. The call letters for the radio station will still be KPCC after the re-brand is completed.[4]

KPCC reaches 600,000 listeners each week.[5]
