KLOS broadcasts in HD Radio.[2] Prior to the station's sale to Meruelo, former AM sister station KABC's talk format was heard on an HD2 subchannel.



Early yearsEdit

The station first signed on December 30, 1947 as KECA-FM, simulcasting the programming of AM sister station KECA. The two stations were owned by ABC and, in 1954, the call letters of the AM and FM stations were accordingly changed to KABC and KABC-FM, respectively. In 1960, KABC adopted an all-talk format. On January 1, 1968, due to new Federal Communications Commission (FCC) rules requiring FM stations to have separate programming from their AM counterparts, KABC-FM experimented with a schedule of all-news radio, the first station in Los Angeles so formatted. This experiment did not last long; KABC-FM dropped all-news programming on March 11, 1968, the same day that KFWB switched to the format.

Rock formatEdit

In early 1969, KABC-FM adopted a progressive rock format known as "Love". Under the direction of Allen Shaw, head of ABC FM Special Projects, the automated programming aired on ABC's other owned-and-operated stationsKGO-FM in San Francisco, KQV-FM in Pittsburgh, WABC-FM in New York City, WLS-FM in Chicago, and WXYZ-FM in Detroit.[3] The syndicated format was voice-tracked by Brother John Rydgren.

Not long after its debut, Love was dropped in favor of live, locally programmed freeform rock music at KLOS and its FM sister stations. In 1971, the station adopted the KLOS call letters[4] to avoid confusion with its AM talk station.[5] In late 1971, the freeform progressive rock sound ended, as Shaw and KLOS program director Tom Yates launched the first album-oriented rock (AOR) station in the United States. Under AOR, KLOS played only the top tracks from the best-selling rock albums and used the slogan "Rock 'N Stereo". The initial slate of disc jockeys on KLOS includes Jeff Gonzer, J.J. Jackson, Jim Ladd, and Damion. By 1972, KLOS had become the top-rated FM rock station in Los Angeles.[6] The station promoted an outdoor rock concert called "California Jam", held April 6, 1974 at the Ontario Motor Speedway in Ontario, California.

KLOS has sponsored a blood drive in conjunction with the American Red Cross annually since 1982. Blood donation centers are set up throughout the station's listening area for several days, usually in the summer months when donation levels are typically low.[7] In 2014, the blood drive collected approximately 7,900 units of whole blood, which can be separated into red blood cells and plasma. As a token of gratitude, the station has given donors rewards such as T-shirts and vouchers toward concert tickets.[8]

In the spring of 1987, KLOS general manager Bill Sommers hired longtime rock radio programmer Charlie West to be the station's new program director. West hired Stephanie Mondello as music director for the station. By fall, West brought Mark & Brian (Mark Thompson and Brian Phelps) to KLOS for morning drive. The station's Arbitron ratings grew steadily under West's direction; by 1988, KLOS emerged as the leader among Los Angeles album rock stations, finishing fifth overall in the market with a 4.3 share, up from a 3.6 the previous ratings period.[9] When West left KLOS in early 1989, Mondello assumed programming duties, directing all key decisions and overall revenue and ratings strategies. The station maintained its fifth-place ranking overall in the market and reached the number-one position in its target young male demographics, defeating main rivals KLSX, KROQ-FM, and the upstart KQLZ (Pirate Radio). Mondello left KLOS in late 1990.

By 1994, KLOS was facing increased competitive pressure from KROQ-FM with the rise of its grunge-based modern rock format as well as KLSX and KCBS-FM (Arrow 93) which focused on classic rock. The station altered its format in response, dropping its existing DJs and most of the classic rock music in favor of more alternative rock content.[10] This experiment last only about three years, after which most of the alternative music was jettisoned and the classic rock returned. In 1997, KLOS hired John Duncan, previously at KYYS in Kansas City, Missouri, as program director and took the station in an adult rock direction. As part of his efforts to turn around the station, Duncan brought back Jim Ladd and hired Garth Kemp and other longtime Los Angeles radio personalities. During this period, KLOS ran a billboard campaign with lines such as, "We lost our mind for a moment, but we're okay now". Within eight months, the station moved from number 18 to fifth place among Los Angeles adults ages 25-54, reclaiming its status as L.A.'s top adult rock station. Duncan left KLOS in late 1998.

In 2005, classic rock rival KCBS-FM flipped to adult hits as "Jack FM".[11] The switch made KLOS the market's only full-time classic rock station until the launch of KSWD (100.3 The Sound) in April 2008.

In October 2006, KLOS restructured its daily lineup of radio hosts, Cynthia Fox, "Uncle Joe" Benson, and Jim Ladd saw each of their daily air shifts increased by one hour. However, this resulted in the temporary dismissal of former evening DJ Gary Moore; he returned in late 2007. Former overnight jock Mark Miller, previously from the long-defunct KQLZ, hosted The Best of Mark & Brian Saturday Special shows Saturday mornings. Miller's overnight shift was replaced with automated programming, billed as "KLOS After Hours". This show follows the usual classic rock format, though occasionally KLOS plays deep cuts and live versions of songs that are not usually played during the daytime.

In 2007, the station came under the ownership of Citadel Broadcasting after it merged with The Walt Disney Company's ABC Radio.

Occasionally, KLOS abandoned its format to air an "A to Z" special, where songs from the KLOS library were played alphabetically by title. Running 24 hours a day (with breaks only for Mark & Brian and Jim Ladd's show), it generally lasted about two weeks with no songs repeated. Unlike the station's regular playlist featuring primarily classic rock hits, the A to Z also included a large number of obscure album tracks. In its final years, the A to Z special aired around the Christmas holidays. Since the dismissal of program director Rita Wilde in 2009,[12] the A to Z countdown has not aired on KLOS. However, then-classic rock competitor KSWD, which hired Wilde, revamped the idea with a very similar, though shorter, compilation of familiar hits and deep tracks.

Cumulus eraEdit

On September 16, 2011, Cumulus Media purchased Citadel, acquiring KLOS and sister station KABC.[13]

On August 17, 2012, Mark Thompson and Brian Phelps appeared on KLOS for the final time, effectively ending The Mark & Brian Show after 25 years (including two years on previous station WAPI in Birmingham, Alabama).[14] Three days later, on August 20, Cumulus announced that Heidi Hamilton and Frank Kramer, former hosts on KLSX and KABC, would host morning drive beginning September 4.[15] On August 15, 2016, Cumulus announced that Frosty Stillwell, with whom Hamilton and Kramer have co-hosted at the same two stations, would join the duo weekday mornings effective September 6.[16]

In February 2016, KLOS launched Horns Up, a Saturday evening program hosted by Stew Herrera[17] that featured heavy metal music. The show has since been replaced with a regular classic rock mix.

On February 8 and 9, 2018, KLOS was one of 14 Cumulus-owned rock radio stations to take part in the "St. Jude Rocks" nationwide fundraising campaign. KLOS listeners contributed more than $725,000 to St. Jude Children's Research Hospital in Memphis, Tennessee as part of the over $2 million total raised by participating Cumulus stations.[18]

Meruelo Media eraEdit

On April 15, 2019, Cumulus announced the sale of KLOS to Meruelo Media for $43 million. This brings KLOS under common ownership with rhythmic top 40 station KPWR, classic hip-hop outlets KDAY and KDEY-FM, and regional Mexican station KXOS (which would be purchased by Meruelo over a month later the KLOS sale announcement, but that radio station on 93.9 is also now as of July 18th, 2019 is Spanish rhythmic contemporary driven rival KLLI (FM) as Cali 93.9), as well as two Spanish-language television stations, KBEH and KWHY-TV. Meruelo began operating KLOS under a local marketing agreement beginning on April 16;[19] the transaction closed July 17.[20] The sale to Meruelo Media comes shortly after the sale of former sister station WPLJ in New York City, as both KLOS and WPLJ were initially owned by ABC. Under the aegis of Allen Shaw, both stations were given the "Love" format followed by, in 1971, the live-and-local AOR format, together retaining the latter for 12 years (WPLJ flipped to top 40 in 1983; it became a non-commercial Christian music station as K-Love in 2019). The sale consummated on July 17. 2019.[21]

Notable personalitiesEdit

Throughout its history as a rock station, KLOS has been home to many prominent progressive rock and AOR DJs.

Chris Carter hosts a locally produced version of Breakfast with the Beatles on Sunday mornings. Prior to landing at KLOS, Carter was heard on KACD-FM (Channel 103.1) in 2000 when it played adult album alternative (AAA) music. He is also the former bass player and producer for Dramarama and produced and supervised the music for the film Mayor of the Sunset Strip, a rock documentary about influential Los Angeles DJ Rodney Bingenheimer of KROQ-FM.

Bob Coburn (1980-1994), a former program director in Chicago and an assistant program director at KMET hosted the syndicated program Rockline. He later worked at KLSX, KCBS-FM (Arrow 93), and KZLA before returning to KLOS. Coburn died of lung cancer December 17, 2016 at age 68.[22]

Marc Coppola, who moved on to KGB-FM in San Diego, was on KLOS in 1977 and reappeared when it aired Westwood One's Rock 'N Roll Never Forgets. Damion and Steve Downes both co-hosted with Marc from 1986 to 1990.

Dion hosted late nights on a part-time basis for several years. He also hosted at KLSX during its classic rock era. In 2005, Al Ramirez, another longtime late night DJ at KLOS, died of natural causes at the age of 54.

Cynthia Fox, former KMET and KLSX personality, hosted the weekday show In Tune at Noon, featuring a daily celebration of events in rock and roll history and in the news. She left KLOS in July 2013 and eventually joined rival classic rock station KSWD.[23][24]

Jim Ladd presented his shows in a freeform manner, interrupting the regular classic rock format during his show middays and Sunday evenings. Ladd picked the music personally, often based on listener requests, and played it in thematic sets. On Wednesday nights at midnight, Ladd devoted an hour to "Headsets", which combines music with a slightly more "sonic" quality (designed to be heard with headphones, or with no background noise interfering), spoken-word poetry, and audio clips from movies and television. On Sundays, Ladd presented "Theme of Consciousness", with all songs within a three-hour window devoted to a singular word or "theme" and chosen entirely by the listening audience.[25] In addition to his work with KLOS, Ladd also appeared on KNAC during its progressive era, KMET, and KLSX. Often dubbed "The Last DJ", after the Tom Petty song that was written about him, Ladd was allowed unusual latitude in selecting the music for his program. His show was routinely the number-one music-based show in its time slot. Ladd left KLOS in October 2011 and joined SiriusXM the following January, hosting daily on the Deep Tracks channel.[26]

Joe Reiling (1977-1981, 2003-2009) started the Local Music Show (later renamed Local Licks). Most of Reiling’s time away from the station found him hosting his own alternative rock show worldwide on AFN (American Forces Network, formerly AFRTS, Armed Forces Radio and Television Services). He was also involved in managing, producing and programming the in-flight audio entertainment for many domestic and international airlines as well as Air Force One. Joe died October 7, 2017.[27]

Frank Sontag hosted a public affairs call-in talk show that aired Sunday nights and early Monday mornings. He was part of the Mark & Brian morning team and ran the control board, also contributing to the show at times. Sontag left the station in 2009; in 2013, he became the host of a Christian talk and discussion program, The Frank Sontag Show, on KKLA-FM.[28]

Mark Thompson and Brian Phelps were the titular co-hosts of Mark & Brian, a morning drive sketch comedy show that aired from September 8, 1987 until August 17, 2012. Highlights from the show aired weekdays for one hour before each regular weekday program. A recap edition, featuring the best of Mark & Brian each week, aired Saturday mornings.

Other former KLOS personalities include Geno Michellini, "Uncle" Joe Benson, Steve Downes, and full-time fill-in Lynda Clayton. Denise Westwood (2000-2016), formerly at KMET, was heard on KLOS handling weekends and fill-in shifts. During her last few years at KLOS, Westwood also hosted the Sunday morning public affairs show Spotlight on the Community. Former program director Rita Wilde, who later went on to KSWD, had been choosing the music on KLOS for decades;[12] afternoon DJ Joe Benson also left for KSWD.
