KOOL-FM's studios are located in downtown Phoenix, and its transmitter is in South Mountain Park.
The Dan Coffey Show, which aired on Saturday and Sunday nights, from 6:00 to midnight, immediately became the most popular program on KOOL-FM – so much so that they hired a woman (Pam MacKenzie) whose only job it was to answer the flood of calls and music requests for the Dan Coffey Show.
At the time, no other station in the Phoenix market had an oldies format, and Osborne was given the freedom by KOOL-FM (then owned by Gene Autry) to play anything he wanted.
This new format caught on and not only became a ratings success but also syndicated itself 24 hours a day, the first radio station to do so.
In late 1995, KOOL-FM began simulcasting on KOOL-AM, which stopped playing "older-leaning oldies".
They opted to sell KOOL-AM-FM to Salem Media in 1997 and the AM, renamed KPXQ, became a Christian Talk station.
In February 2008, CBS Radio made major layoffs that sent many longtime personalities packing, including Bill Gardner, John Michaels, Camelback Jack (who will later return), Dave Shannon (who with Gardner were the oldest workers in the building and had just received a bonus check for great ratings), and several part-time personalities that had been with the station over the years, including Liz Boyle, Dennis Mitchell and Tony McGraw, a.k.a.
With the public release of Arbitron PPM data in July 2009, KOOL-FM continued to be one of the most listened-to stations in Phoenix[4] with an airstaff anchored by 30-year market veterans Tom Peake and Steve Goddard along with the return of Camelback Jack at night and radio veteran Jeffrey T. Mason in middays.
On September 28, 2022, at 10 am, after playing "I Want To Know What Love Is" by Foreigner, KOOL-FM began stunting with a loop of jingling sleigh bells and a voice like that of Santa Claus announcing "something special" was coming soon.
