KIMN (100.3 FM, "Mix 100") is a Hot AC radio station in Denver, Colorado. The station broadcasts at 100.3 MHz with an effective radiated power of 97 kW and is under ownership of Stan Kroenke's KSE Radio Ventures. Its studios are located on Colorado Boulevard in Glendale, and the transmitter site is on Mount Morrison west of Lakewood.
The station signed on the air on August 8, 1959 as KLIR and spent most of its life with an MOR format and as a beautiful music outlet. 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 would revert to the "Majic 100" moniker, and in 1992, would reclaim the KMJI call letters, with the format evolving to an all-'70s direction in June 1994. The KIMN calls were picked up on April 18, 1995, along with the name "KIM 100."
On March 3, 1997, KIMN returned to AC (again as "KIM 100"). 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.
In the summer of 2014, KIMN updated its moniker to "Mix 100.3" and changed its positioning statement from "Denver's Best Music Mix" to "All The Hits", while shifting towards Top 40 (CHR). Despite the format shift, 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 and Rhythmic Top 40 KQKS (both of which are 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, owned by Altitude Sports and Entertainment founder Stan Kroenke, announced they would acquire Wilks Broadcasting's Denver properties, including KIMN, Country KWOF, and Oldies KXKL-FM. Once the sale was approved by the FCC, KSE was expected to flip one of the three outlets to Sports, which could see the Denver Nuggets, Colorado Avalanche, and Colorado Rapids moving from its current home in Denver, which is KKFN. The transaction was consummated on December 31, 2015, at a purchase price of $54 million.
