KPFK was founded in 1959 as the second station of the
Pacifica Foundation.
Terry Drinkwater was its first general manager. In 1960, KPFK won Pacifica's second
George Foster Peabody Award for excellence in broadcasting. In 1962, the
FCC withheld the license renewals of
KPFA,
KPFB, and KPFK, pending its investigation into "communist affiliations." Pacifica was never cited (see
The Investigator). In 1963, KPFK ran the first
Renaissance fair as a fundraiser called the Renaissance Pleasure Faire and May Market (the event was managed by Theme Events Limited). At the 1964 fair,
Art Kunkin distributed
The Faire Free Press, a one-shot eight-page
tabloid with the "
Los Angeles Free Press logo appearing on an inside page. While the outside pages were a spoof of the Faire's Renaissance theme, featuring cute stories like one about a "ban the
crossbow" demonstration, the inside contained legitimate underground community news and reviews. Five thousand copies were printed, of which 1,200 sold at a price of 25 cents. After the Faire ended, Kunkin circulated a brochure to potential investors and found enough backing to start putting out the paper on a regular weekly basis in July 1964. The
Los Angeles Free Press was initially produced mostly by unpaid volunteers, many of them were the same people who volunteered at KPFK, where Kunkin had his own political commentary radio show.
Peter Bergman's
Radio Free Oz was first broadcast on July 24, 1966.
The Firesign Theatre first appeared on
Radio Free Oz on November 17, 1966. The Fireside Theatre produced the live radio program
Dear Friends on KPFK in 1970–1971. Twenty-one episodes aired between September 16, 1970, and February 17, 1971.
Dear Friends was followed with the KPFK show ''Let's Eat!'' in 1971 and 1972. In 1974, Will Lewis, the general manager of the station at the time, famously refused to turn over tapes acquired from the
Symbionese Liberation Army after the terrorist group's kidnapping of newspaper heiress
Patty Hearst. After repeated requests by the
FBI and being subpoenaed, Lewis cited the
First Amendment guarantee of freedom of the press to no avail at a
grand jury and was sent to federal prison for 15 days at
Terminal Island. Lewis was finally released by Supreme Court justice
William O. Douglas. Lewis shared a prison cell with controversial LSD guru
Timothy Leary. Lewis was just the second media representative to ever be sent to jail on a freedom of the press issue. Lewis' progressive changes at KPFK during the 1970s turned the Pacifica station into one of the most popular in the nation, where many celebrity activists were able to express their views without censorship from mainstream media. Actors
Martin Sheen,
Paul Newman,
Jane Fonda and her then-politician husband
Tom Hayden, who stood trial in the
Chicago Seven case, were among many high-profile visitors at the station during Lewis' leadership. Lewis was a manager ahead of his times. In 1974, he was the first to introduce a radio show produced and hosted exclusively by and for the gay community — "The Great Gay Radio Conspiracy" as Greg Gordon, Enrich Murrello, and Colin McQueen began the program at 11 pm the third Tuesday of every month. This controversial program eventually was referred to as "IMRU," as it created great consternation for a mostly conservative audience. Today, the program is still a fixture on KPFK as the longest-running LBGTQ program some 48 years later. KPFK was the only full-service public radio station in Los Angeles during the early 1970s. Lewis and the station won awards for its Watergate coverage, including the
Golden Mike Award for reporter
Mike Hodel.
Jerker, a
Robert Chesley play dramatizing the reflections of a man dying of AIDS, aired on KPFK on August 31, 1986. Because it included graphic sexual language, the
FCC ruled that it violated an
indecency policy. In 1987,
Ladysmith Black Mambazo made their first on-air U.S. radio broadcast on KPFK. In 1992,
CPB Board member
Victor Gold targeted KPFK for strident African American programming and controversial speech aired during
Black History Month, by filing an
FCC complaint. The first two decades of the 21st century were marked by conflict at the station over programming as well as money worries. After the Russian Invasion of Ukraine in 2022, the Russian government sponsored networks went off the air in the US. Some of their reporters made the way to KPFK and two other Pacifica stations. In 2024, it was announced on the air that the station building had been sold to be converted to a recording studio. Provision was made for KPFK to have free access to a portion of the new building for ten years once it was completed. The station broadcast from temperary quarters in Burbank in interim. By January of 2025 the new interim station manager,
Maggie LePique revised the line up of political programming. The pro Russia shows, such as the KPFK Rebel Alliance News, were removed from prime listening hours and the progressive shows like Background Briefing with Ian Masters returned. Fringe pro Russia, China, ( and their allies Iran, Syria's Assad, Venezuela's Maduro) podcasts like The Grey Zone with Max Blumenthal and the former Stutnik and Russia Today regulars were played in the early hours of the morning, however. ==Translators and booster==
