The station has studios at the intersection of Wilshire Blvd. and Hauser Blvd. in the Miracle Mile neighborhood of Los Angeles. The transmitter is based in the Verdugo Mountains. It was the flagship station of Kevin & Bean and Loveline which was originally hosted by Jim "The Poorman" Trenton with Dr. Drew Pinsky.

History KPPC

On April 23, 1962, KPPC-FM signed-on on 106.7 MHz. It was owned by the Pasadena Presbyterian Church as a companion to its KPPC, a limited-hours AM radio station that had broadcast since 1924.

In 1967, the Pasadena Presbyterian Church sold KPPC-AM-FM to Crosby-Avery Broadcasting for $310,000. The church had been attempting to sell the radio stations for a year; station manager Edgar Pierce said the church found commercial radio incompatible with the noncommercial nature of its other efforts. Crosby-Avery was owned by Leon Crosby, a general manager of San Francisco's KMPX, a station that had just gone to a full-time freeform progressive rock format, and Lewis Avery, former partner in a national ad sales firm. With KMPX soaring to success but KPPC, with its middle-of-the-road format, ailing, Crosby and Avery brought in the architects of KMPX, Tom and Raechel Donahue, to turn around their new station in Southern California.

Hosts during KPPC's "underground" format included B. Mitchel Reed, Tom Donahue, Les Carter, Ed Mitchell, Steven Clean, Outrageous Nevada, novelty music historian Dr. Demento, Charles Laquidara, Elliot Mintz, blues archivist Johnny Otis, Barbara Birdfeather, and more.

In 1969, Crosby sold KPPC-AM-FM and KMPX to the National Science Network for $1.2 million. Crosby used the funds to buy a then-silent San Francisco television station, KEMO-TV. National Science Network's management of the KPPC stations was turbulent, capped by an October 1971 mass firing of the air staff, but the period also included technical upgrades. NSN moved the studios out of the church basement and to 99 Chester Street in Pasadena and the transmitter to Flint Peak, with a slight power increase to 25,700 watts.

In 1971, Ludwig Wolfgang Frohlich, founder of the National Science Network and previous owner of an ad agency, died. Upon his death, control of the estate was transferred to Ingrid and Thomas Burns.

KROQ AM and KROQ-FM Beginnings and brief closing (1972–1974) Country music station KBBQ (1500 AM) in Burbank became KROQ in September 1972, changing its format to Top 40 and hiring established disc jockeys from other stations. The new KROQ called itself "K-ROCK, the ROQ of Los Angeles". In 1973, with National Science Network's estate selling off its assets, KROQ's owners bought KPPC-AM-FM (immediately divesting the AM station to meet then-current ownership limits), changed the calls to KROQ-FM and hired Shadoe Stevens to create a new rock format described as high-energy "all-cutting-edge-rock-all-the-time" and began simulcasting as "The ROQs of L.A.: Mother Rock!" Meanwhile, KPPC on 1240 AM was sold to Universal Broadcasting, a religious broadcaster, and remained on the air with its limited-schedule of Wednesday evening and Sunday operation until subsequent owners took the station off the air permanently in 1996.

The two stations (KROQ-AM/FM) were wildly successful initially with the new format, but poor money management plagued the enterprise. When concert promoter Ken Roberts booked Sly and the Family Stone and Sha Na Na for one KROQ-sponsored show at the Los Angeles Coliseum and the station found itself unable to cover expenses, Roberts agreed to pay for the band to play the show in exchange for a small ownership stake in the station.Elaine Woo, "Ken Roberts Dies at 73; Promoter Transformed KROQ-FM into a Powerhouse," Los Angeles Times, July 4, 2014. Roberts joined a sprawling ownership group which included a doctor, two dairymen, a political lobbyist, a secretary, and several other minor investors. Roberts, with his background in the music industry, made him a logical choice for president of the struggling company in the minds of the other shareholders, and he was elected such at the first meeting he attended in 1974.

By 1974, the station's finances were already untenable following a year of commercial-free programming – a stunt implemented in an effort to gain market share. The stations' debt load reached $7 million; paychecks began to bounce and Shadoe Stevens and the bulk of the staff walked out, shutting the stations down. The closure would last for nearly two years.

Rebirth and increasing popularity (1975–1989) In late 1975, the FCC ordered KROQ to return to the airwaves or surrender the stations' licenses. With barebones equipment, KROQ returned to the airwaves, broadcasting initially from the transmitter location, followed by a penthouse suite in the Pasadena Hilton Hotel, then again across the street from the Hilton (117 S. Los Robles).

Ken Roberts returned to the reborn station in a more forceful ownership role, buying out his partners one by one until he remained the sole owner of the station.

KROQ's rebirth was simultaneous with the emergence of punk rock in the late 1970s and new wave, and KROQ quickly became the voice of the burgeoning Los Angeles punk and new wave scene. Disc jockey Rodney Bingenheimer introduced many new bands on his show. As punk expanded its hold on the music scene during the mid to late 1970s, and KROQ steadily adding more of it to their freeform format, this cemented their place in the Los Angeles market.

In 1979, Shadoe Stevens once again left the station, with Rick Carroll taking over as program director, and took all of the new music and combined it in a Top 40 formatic structure. By 1980, the station had fully committed to a post-new wave modern rock orientation. KROQ became an even greater success as the "Rock of the 80s" evolved. During that decade, the station mixed punk rock, such as the Ramones, the Clash, the Weirdos, Fear, the Pandoras and X, with new wave, such as U2, Oingo Boingo, Talking Heads, the Police, the Cars, Devo, Sparks, Berlin, Duran Duran, Pet Shop Boys, Blondie, the Go Go's, Squeeze, Culture Club, the Jam, Elvis Costello, the Bangles, Bananarama, the Cult, the Cure, ska and similar genres with artists such as English Beat, Fine Young Cannibals and 1960s underground rocker Iggy Pop, and huge mainstream artists such as the Beach Boys and the Rolling Stones. It was also not uncommon for certain KROQ dee-jays to play then-current hip hop and soul/funk artists such as Arrested Development, Prince and Parliament/Funkadelic.

By 1982, Billboard magazine reported that KROQ Arbitron numbers of 3.7 were closing in on AOR leaders KMET at 4.0 and KLOS at 3.9.KROQ Surge stirs L.A. AOR Scene. Billboard, July 10, 1982

Carroll, as a consultant, took the "Rock of the 80s" format to other stations, including 91X in San Diego, KOEU in Palm Springs, California, KMGN FM in Bakersfield, California, The Quake in San Francisco and KYYX in Seattle, among a few others on the US West Coast in the 1980s.

In 1986, KROQ was purchased at a then-record $45 million by Infinity Broadcasting. By the late 1980s, the station had started dipping in the ratings. New wave had declined in popularity and electronic dance bands, such as Depeche Mode and New Order, started getting more airplay on the station. Also during this period, KROQ began focusing on college rock (or so-called alternative rock) by adding bands into their playlist such as R.E.M., the Red Hot Chili Peppers, the Psychedelic Furs, ABC, the Smiths, Frankie Goes to Hollywood, Bronski Beat, Echo & the Bunnymen, the Replacements, Camper Van Beethoven, Jane's Addiction, the Pixies, the Alarm, the Cult, Violent Femmes, Love and Rockets, Dramarama, and Social Distortion, as well as heavier acts like Faith No More and Living Colour and guitar-oriented hip-hop groups like Run-DMC and the Beastie Boys.

KROQ in the 1990s and continued popularity (1990–1999) Throughout the 1990s, KROQ's format focused on mainly alternative rock (or alternative metal), grunge, pop-punk, Britpop, industrial music and nu metal, giving up-and-coming bands their first exposure on the station or in Southern California, including Nirvana, Red Hot Chili Peppers, the Smashing Pumpkins, Pearl Jam, Nine Inch Nails, Oasis, the Gin Blossoms, Foo Fighters, Green Day, the Offspring, Sublime, No Doubt, Rage Against the Machine, Korn, Bad Religion, Weezer, Blink-182, Jimmy Eat World, Hole, Garbage, Lenny Kravitz and System of a Down. They also began adding heavier acts to their playlists such as Metallica, Soundgarden, Alice in Chains and Tool, all of whom were staples on the Long Beach heavy metal radio station KNAC, formerly an alternative/new wave/punk rock radio station. These helped the station surge back to number one in the ratings, at which it remained until the mid-2000s, when it slipped to the middle-of-the-pack, ratings-wise, for Los Angeles area radio stations.

The 1990s also saw a continuation of the weekday morning Kevin & Bean Show, as well as "Rodney on the Roq," hosted by Rodney Bingenheimer, on Sunday nights. In late nights, the station aired Loveline, hosted by "The Poorman" Jim Trenton and Dr. Drew Pinsky. The show's purpose was to bring correct information regarding human sexuality and relationships to those 13 to 25 years of age. KROQ also began its own festivals Almost Acoustic Christmas and Weenie Roast, which had taken place every year since 1990 and 1993 respectively; due to the COVID-19 pandemic, there were no lineups for Almost Acoustic Christmas in 2020 and 2021, while there have been no editions of the Weenie Roast since 2019.

In June 1990, Kevin and Bean secretly arranged for a friend to pretend to confess to killing his girlfriend during their "Confess Your Crime" segment. The hoax resulted in investigations by the Sheriff's Department, the FCC, NBC's Unsolved Mysteries and other news media. The hoax was exposed 10 months later after KROQ had unknowingly hired the caller, Doug "the Slug" Roberts, as a DJ and the three were heard talking about the hoax on a monitored phone line at KROQ. Kevin and Bean paid the Sheriff's Department $12,170 for the cost of the investigation, and performed 149 hours of community service to compensate for the 149 hours the homicide detective spent on the case. KROQ received a letter of reprimand from the FCC for the incident, the lightest punishment the FCC could give.

In 1997, KROQ/Infinity merged with CBS, later changing its name to CBS Radio.

Later history (2000–2016) Originally located at 117 S. Los Robles Avenue in Pasadena, the station moved to 3500 W. Olive Avenue in Burbank in 1987 as part of the purchase agreement and to be closer to the music industry. In 2002, the station was moved to a facility at 5901 Venice Boulevard in the Crestview neighborhood in West Los Angeles.

Unlike most other (Class B, but with grandfathered greater than B facilities) FM stations in Los Angeles whose transmitters are atop Mount Wilson, KROQ's (Class B) transmitter is located on Tongva Peak in Glendale at an altitude of 2,650 ft., which results in somewhat weaker signal coverage.
