KMPC became part of the Goodwill Station group that included WJR in Detroit and WGAR in Cleveland, both also owned by Richards.

During Autry's ownership, KMPC was a full service middle of the road station, featuring popular music, news and sports.

Dick Whittinghill, Geoff Edwards, Wink Martindale, Gary Owens, Bob Arbogast and Roger Carroll formed a powerhouse lineup of disc jockeys during the 1960s and 70s.

KMPC also aired a weekday evening sports call–in show hosted by Scott St. James, who was also a TV soap opera actor on the side.

Whittinghill, Owens, Johnny Magnus and Pete Smith went over to KPRZ and played standards as part of "The Music of Your Life" format.

[12] On February 24, 1997, ABC Radio changed KMPC's call sign to KTZN, and flipped to a women's talk format.

As an ESPN Radio outlet, KSPN began on the former KRLA (1110 AM, now KWVE) in December 2000, after ABC purchased that station from Infinity Broadcasting.

Steve Mason & John Ireland, football player D'Marco Farr and longtime ESPN personality Gary Miller were among the hosts who rotated through the midday slot from 2004-2007.

Mason, sans Ireland, moved into the 1-4 p.m. time slot, followed in afternoon drive by a new show hosted by Dave Dameshek, a member of the Jimmy Kimmel-Adam Carolla comedy connection.

Dameshek eventually began a podcast-only show that has become among the parent network's more popular Web offerings, while Denholm and Long continued in afternoon drive.

On July 10, 2009, unofficially known as "710 Day," L.A. Sports Live with Andrew Siciliano and Mychal Thompson premiered from 11 a.m. to 3 p.m. Mason and Ireland returned to their old drive time slot (3-7 p.m.), replacing Denholm and Long.

The Scott Van Pelt and Dan Le Batard shows moved over to secondary ESPN affiliate KLAA.

Thompson's first move at KSPN was to replace Siciliano with a new show hosted by New Yorker Max Kellerman and former NFL player Marcellus Wiley.

Mychal Thompson remained as a Lakers analyst and became a morning show host with Mark Willard, who was let go from the station on August 29, 2014.

That was followed by the ESPN Network's Stephen A. Smith, hosting the late morning show, followed by "Mason and Ireland" in the early afternoon.
