KLAC AM 570 is a radio station serving the Los Angeles metropolitan area. KLAC is one of eight Los Angeles radio stations owned by San Antonio-based Clear Channel Communications. The station is co-located with its sister stations in suburban Burbank, and its transmitter is located on a site in the Lincoln Heights neighborhood of Los Angeles, east of downtown.
Since January 2009, the station has been the flagship of Fox Sports Radio and now originates most of the networks' programming, including The Loose Cannons with Pat O'Brien, Steve Hartman and Vic "The Brick" Jacobs, The Petros and Money Show, and Into The Night with Tony Bruno.
Early years 
KLAC began as KFPG in 1924. In 1925 it became KMTR after new owner K.M. Turner, a radio dealer. In 1946, Dorothy Schiff, publisher of the New York Post, bought the station and renamed it KLAC. The station was purchased by Metromedia in 1963. They ran a pop music format from the 1950s into the 1960s, similar to other AM Metromedia stations. KLAC at different times featured the talents of Les Crane and Lohman and Barkley.
In the mid-1960s KLAC had a talk format known as "two-way radio" including Joe Pyne, then became a middle of the road station playing music from the 1940s and early 1950s along with soft rock and non-rock hits of the 1950s and 1960s. By early 1970, KLAC evolved to more of an adult contemporary format focusing on soft rock hits from 1964 up to that time.
Country stations KFOX and KBBQ did not have a signal as powerful as that of KLAC, so on September 28, 1970, KLAC decided to drop adult contemporary for country. Number one on their first Big 57 survey was "For The Good Times" by Ray Price. Original DJs were Deano Day, Gene Price, Harry Newman, Sammy Jackson and Jay Lawrence, joined the following year by Dick Haynes and Larry Scott. L.A. veteran Nancy Plum (KTNQ, KMPC) was heard in the last days of the country format. Many of the KLAC airstaff had previously worked at KBBQ.
In the fall of 1980, KZLA-AM-FM joined the country music competition, followed in December 1980 by KHJ. KHJ went back to pop oldies on April 1, 1983. KZLA-AM/FM and KLAC competed through the 1980s. During this time, KLAC DJ Harry Newman could also be heard as the image voice for KCOP-TV, which had been co-owned with KLAC until the late 1950s. (Interestingly, KCOP would become sister station to KTTV, which was co-owned with KLAC for 21 years.)
In 1984, Metromedia sold KLAC to Capital Cities Communications, which subsequently sold its previous Los Angeles AM station, KZLA (1540, now the current KMPC) to Spanish Broadcasting System. One year later Capital Cities announced its acquisition of ABC. As the newly-merged Capital Cities/ABC opted to retain KABC and KLOS, both KLAC and KZLA-FM were sold, with both outlets going to Malrite Communications. The station moved to classic country from the 1950s to the 1970s, though one exception to the music format was a "combat talk" show hosted by Orange County conservative icon Wally George on Monday nights during the late 1980s and early 1990s.
In late 1993, KLAC fired all their DJs and newsman, including 31-year veteran Dean Sander, and dropped country for Westwood One's satellite-fed standards format, focusing on artists like Nat King Cole, Neil Diamond, Peggy Lee, Petula Clark, Dean Martin, Barbra Streisand, Frank Sinatra, Johnny Mathis, The Carpenters, Elvis Presley, the Ames Brothers, Tony Bennett, Perry Como, Dionne Warwick and Barry Manilow. Big bands were no longer played. KLAC stayed with this format in some form until 2001.
KLAC was owned by Malrite until 1993, when the station was sold to Shamrock in a group deal along with KZLA. In 1995, the station was absorbed by Chancellor Media and KZLA was swapped to Bonneville in the late 1990s. Chancellor Media would form AMFM inc when it merged with capstar in 1999. In 2000, AMFM inc would merge with Clear Channel making KLAC a Clear Channel station.
On September 12, 2002, KLAC reverted to an adult standards format, becoming the Fabulous 570. In addition to many of the station's previous artists, the playlist included Norah Jones, Diana Krall, Harry Connick Jr., Rod Stewart and Michael Bublé, whose music was influenced by the standards artists. During the standards/lounge music period, Brad "Martini" Chambers, Jim "Swingin' Jimmy D" Duncan, Daisy Torme (Mel's daughter) and the omnipresent Gary Owens were among the air talent.
"XTRA Sports 570" 
On February 4, 2005, Clear Channel Communications conducted a far-reaching format swap of three radio stations in the area.
Among the changes:
- KLAC's previous standards format, and "Fabulous" branding, moved to XETRA 690-AM and became The Fabulous 690. It would last until February 1, 2006, when with an ownership change and ending of Clear Channel's programming lease, 690-AM became W Radio XEWW, a Spanish-language talk station.
- The XTRA Sports format, simulcast on XETRA 690-AM in San Diego and KXTA 1150-AM in Los Angeles, moved to KLAC, which initially aimed at both Los Angeles and San Diego. (Prior to 2002, they were separately programmed stations, with the only common programming being Rome's show.)
- KXTA became KTLK, hosting a progressive talk format.
When the initial merger took place, the only surviving hosts that are still affiliated with the station to this day are Jim Rome and sportscaster Steve Hartman (both were holdovers from the 690 days) as well as one-time Los Angeles TV sportscaster Vic "The Brick" Jacobs (the only surviving holdover from the 1150 days).
All of the other remaining hosts from either 690 or 1150 went on to other stations, including many of the former XTRA Sports 690 hosts joining the upstart sports format at San Diego-based XEPRS-AM (1090 kHz, now known as "The Mighty 1090").
Branding and format tweaks 
In February 2006, the station had phased out the use of the XTRA Sports nickname as part of a re-orientation to the Los Angeles market, and was simply referred to on air as AM 570. The XTRA Sports name was later re-launched in San Diego on November 12, 2007, with Lee Hamilton starting local programming.
For a brief time, AM 570 placed less emphasis on sports and more emphasis on male-oriented programming to compete with the now-defunct KLSX, then the local home of Adam Carolla and Tom Leykis. Local hosts had been instructed to not limit themselves to sports, but also include politics, celebrities, relationships, and current events.  In addition, non-sports hosts Erich "Mancow" Muller and Phil Hendrie were added to the lineup.
The switch also meant that former afternoon host, San Diego sports icon and former NFL Chargers radio voice Lee "Hacksaw" Hamilton (who also, like Rome and Hartman, was a holdover from the sports format's origin on 690) was moved to weekend duty. He would also host a daily 5 p.m. update on KLAC for several months until landing a weekday show on San Diego-based sister station KLSD, which had revived the former "XTRA" brand.
The KLAC calls were initially only announced at the top of an hour by themselves with no other note paid attention to them, but soon were started to be used more often under the "AM 570 KLAC" brand, starting when the station celebrated its 30th anniversary as the Laker radio flagship. Some promotions have spelled out the meaning of the call letters as K Los Angeles California.
Back to sports 
Starting in late 2006, KLAC shifted its focus again to more sports content. Phil Hendrie voluntarily retired from his syndicated show so as to pursue an acting career (but would later revive the program on KTLK). Hendrie's time slot was filled by Joe McDonnell, who would last for two years at KLAC; Into The Night with Tony Bruno, which KLAC co-produced with The Content Factory, replaced McDonnell in September 2008.
Mancow was replaced with Roggin and Simers2(Squared), hosted by Fred Roggin of KNBC (and formerly of one-time rival sports talker KMPC-AM), T.J. Simers of the Los Angeles Times, and Simers' daughter, Tracy Simers. Roggin and Simers2 only lasted 11 months before being replaced by Dan Patrick's syndicated morning show, also produced by The Content Factory, on September 2007.
Former USC running back and former KMPC afternoon talk-show host Petros Papadakis join KLAC in January 2007, teaming up with sportscaster Matt "Money" Smith (then the host of the Lakers Radio Network's pregame, halftime, and postgame coverage) to co-host the stations' 4 to 7p.m. weekday afternoon slot, dubbed the Petros and Money Show.
On December 11, 2008, the Los Angeles Lakers announced that KLAC would no longer be the team's flagship station following the 2008-2009 season, and that Laker games would be moving to KSPN AM 710, ESPN Radio's Los Angeles station.
Merger with Fox Sports Radio 
On January 20, 2009, the station announced a merger with the Fox Sports Radio Network, which effectively ended the shows as local programming. General manager Don Martin emerged as program director for both the station and the network, the latter in which he succeeded Andrew Ashwood, who died a few months earlier.
There was no initial word whether the station programming would continue from the Clear Channel Studios in Burbank, or would relocate to the Fox Sports Radio network offices in Sherman Oaks, which also housed the Premiere Radio studios for Jim Rome. According to a report by Los Angeles Daily News media columnist Tom Hoffarth, Fox Sports Radio hosts Ben Maller, Andrew Siciliano, Krystal Fernandez, Craig Shemon and James Washington were released from their duties.
Shemon and Washington's morning slot would be replaced by Dan Patrick's syndicated morning show, while Chris Myers' and Hartman's midday shows combined into one, Myers and Hartman. Myers replaced Mychal Thompson (who was expected to leave the station at the end of the Laker season) while Vic "The Brick" Jacobs was relegated to reading the sports updates. Siciliano and Fernandez's early evening show was replaced by the Petros and Money Show.
KLAC initially dropped "Into The Night with Tony Bruno," clearing JT The Brick instead. Ben Maller's overnight show, the Third Shift, was canceled and replaced by a clip show entitled Fox Sports Soup. JT The Brick's show would replace Fox Sports Soup later in the year as the network assumed production of Into The Night and rehired Maller for weekend duty.
Myers left Myers and Hartman in March 2010 so as to focus on his other duties with Fox Sports, and would effectively be replaced by Pat O'Brien as co-host of the resurrected Loose Cannons show, alongside Hartman and Jacobs.
