KIMN (100.3 MHz, "Mix 100") is a commercial FM radio station in Denver, Colorado. The station is owned by Stan Kroenke's KSE Radio Ventures and airs a Hot AC radio format. Studios and offices are located on Colorado Boulevard in Glendale, and the transmitter site is on Mount Morrison west of Lakewood.
The airstaff includes the "Mix Morning Show" featuring Dom Testa, Jeremy Padgett and Kris McLaughlin. Other station DJs include Emily Makinzie, and Steve Marshall. KIMN carries the syndicated countdown show American Top 40, hosted by Ryan Seacrest.
KLIR-FM, KXLT and KMJI
On July 9, 1959, the station signed on as KLIR-FM. It was the FM counterpart to AM 990 KLIR (now KRKS). It was owned by George Basil Anderson and had an effective radiated power (ERP) of 8,800 watts, a fraction of its current power. KLIR-FM originally simulcast the AM station but later began airing a beautiful music/MOR format.
On June 7, 1984, the station switched to an Adult Contemporary format as KMJI ("Majic 100"), but would later tweak its direction to Soft AC and change its calls to KXLT ("K-Lite 100"). In November 1991, the station returned to the "Majic 100" moniker, and in 1992, the call letters switched back to KMJI. The format evolved to all-'70s hits in June 1994.
KIM 100/Mix 100
The KIMN call letters were picked up on April 18, 1995, along with the name "KIM 100." From the late 1950s to the early ‘80s, KIMN had been a popular Top 40 station on AM 950, so most Denver radio listeners had grown up knowing the call sign.
On March 3, 1997, KIMN returned to AC, while still calling itself "KIM 100." Chancellor Media (a forerunner of today's iHeartMedia), acquired KIMN in September 1999. Also in 1999, the station evolved into a Hot AC format and adopted the "Mix 100" moniker. For the next several years, weekend programming on KIMN featured music entirely from the 1980s. Infinity Broadcasting, a division of CBS Radio, acquired KIMN in August 2000.
In June 2008, KIMN became the Denver affiliate for the syndicated weekday show "On-Air with Ryan Seacrest." The station discontinued the show in February 2009. In March 2009, CBS Radio sold KIMN, along with sister stations KWOF and KXKL-FM, to Wilks Broadcasting.
Move to Top 40
In the summer of 2014, KIMN updated its moniker to "Mix 100.3", changed its positioning statement from "Denver's Best Music Mix" to "All The Hits", and shifted towards Top 40 (CHR). Despite the format adjustment, KIMN continues to report to both Mediabase and Billboard/BDS's Adult Top 40 charts.
The shift also put the station more in competition with Adult Top 40 rival KALC, owned by Entercom, and iHeartMedia's Top 40/CHR KPTT. In 2016, the station returned to its previous moniker "Mix 100" and a new positioning statement, "Today's Best Mix."
On October 12, 2015, Kroenke Sports Enterprises (KSE), owned by Altitude Sports and Entertainment founder Stan Kroenke, announced it would acquire Wilks Broadcasting's Denver properties: KIMN, Country KWOF, and Classic Hits KXKL-FM. Once the sale was approved by the FCC, KSE was expected to flip one of the three outlets to all-sports. The new FM sports station would likely claim the broadcasting rights to the Denver Nuggets, Colorado Avalanche, and Colorado Rapids from rival FM sports station KKFN, owned by Bonneville International.
The transaction was consummated on December 31, 2015, at a purchase price of $54 million. However, KIMN retained their Adult Top 40 as KWOF made the flip to Sports on September 17, 2018.
The call sign KIMN originally belonged to a Denver AM station located at 950 kHz. From the late 1950s to the early 1980s, KIMN was the dominant Top 40 music station in Denver. The station also highlighted the popular local rock n' roll bands of that era, such as the Astronauts, Daniels, Fogcutters, Moonrakers, Soul Survivors,and others. The station had other nicknames as the Denver Tiger, Boss Radio, and 95 Fabulous KIMN. The station was then owned and operated by Kenneth E. Palmer (1925-1984).
