[3] In 1946, Dorothy Schiff, publisher of the New York Post, bought the station and renamed it KLAC, for Los Angeles, California.

During the 1940s, Douglas Adamson worked as a disc jockey on KLAC and was voted one of Billboard magazine's top ten DJs in America.

Al Jarvis notably hosted a TV edition of the Make Believe Ballroom, and a young Betty White was part of his staff, Regis Philbin and Leonard Nimoy also worked behind the scenes at the station.

The original DJs included Deano Day, Gene Price, Harry Newman, Sammy Jackson and Jay Lawrence, joined the following year by Dick Haynes, Charlie O'Donnell and Larry Scott.

One year later, Capital Cities announced its acquisition of ABC; the newly-merged company opted to retain KABC and KLOS, with both KLAC and KZLA-FM being sold to Malrite Communications.

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 its DJs and newscasters, including 31-year veteran Dean Sander, and dropped country for Westwood One's satellite-fed adult standards service, known as "Stardust."

It played Frank Sinatra, Barbra Streisand, Nat King Cole, Neil Diamond, Peggy Lee, Petula Clark, Dean Martin, Johnny Mathis, The Carpenters, Elvis Presley, the Ames Brothers, Tony Bennett, Perry Como, Dionne Warwick and Barry Manilow.

In 2001, KLAC became a talk radio station, airing syndicated programs from Don Imus, Clark Howard, Dr. Dean Edell, The Truckin' Bozo show,[citation needed] and local host Michael Jackson.

On February 4, 2005, Clear Channel Communications conducted a format swap on three of their radio stations in Southern California, including KLAC.

All on- and off-air personnel were reassigned between the three stations; with KLAC retaining Steve Hartman, Lee Hamilton and Vic "The Brick" Jacobs from both XETRA and KXTA, along with the local rights to The Jim Rome Show.

In February 2006, KLAC 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 KLSD on November 12, 2007, with Lee Hamilton starting local programming.

Local hosts on KLAC were instructed to not limit themselves to sports, but also include celebrities, relationships, politics and current events.

The switch also meant that former afternoon host and one-time San Diego Chargers radio voice Lee "Hacksaw" Hamilton was moved to weekend duty.

Roggin and Simers2 lasted 11 months before being replaced in September 2007 by Dan Patrick's syndicated morning show, also produced by The Content Factory.

[10] On September 23, 2011, the Los Angeles Dodgers announced that KLAC would become the flagship for the team's radio network beginning in the 2012 season.

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.

Siciliano and Fernandez's early evening show was replaced by Petros and Money, who would be carried on Fox Sports Radio between 2009 and 2014.

JT The Brick's show replaced Fox Sports Soup later in the year as the network assumed production of Into The Night and rehired Maller for weekend duty.
