The station has studios and offices on South Monaco Street in the Denver Tech Center, while the transmitter site is atop Lookout Mountain in Golden.

It was owned by Karlo Broadcasting, Ltd. KMYR aired middle of the road music and carried news from ABC Radio.

In October 1993, shortly after Noble Broadcast Group acquired the station, KHOW-FM adopted a smooth jazz format and the call letters KHIH.

In 1996, Noble merged with Jacor, taking advantage of the Telecommunications Act of 1996, allowing one company to own several radio stations in the same market, no longer limited to one AM and one FM.

On September 1, 2000, 95.7 returned to contemporary hits as KFMD, "95.7 KISS FM", giving the market its first Mainstream Top 40 outlet since KHHT's demise in 1997.

On April 27, 2005, KFMD changed call letters to KMGG, and flipped to a Hispanic Urban format as "Mega 95.7.

On September 18, 2006, at Midnight, after ending its "Sunday Night Sabor" show and playing "My Way" by Frank Sinatra, KMGG flipped to a Rhythmic Adult Contemporary format targeting females ages 25–49, branded as "95.7 The Party."

KPTT primarily targeted the older audience of KQKS (as well as the market's other adult contemporary-oriented stations), and was the first adult-oriented rhythmic outlet in Denver since KDJM flipped in December 2005.

KPTT aired a Sunday-Thursday night slow jams program called "Between The Sheets", as well as the syndicated LGBTQ-oriented "Radio with a Twist" on weekends.

In the fall of 2014, KPTT evolved back to a more mainstream Top 40 direction with the inclusion of pop tracks in its playlist, while maintaining a Rhythmic presentation.

[22] On July 2, 2021, morning hosts David ‘Deuce’ Jacobson, Nina Blanco, and Robert ‘Dubz’ Trigilio were released from the station.

This, combined with the recent registration of new web domains by iHeart as early as mid-May, suggested KPTT would undergo a significant overhaul of its format, as the station dropped to 19th place with a 2.0 share in the May 2021 Nielsen Audio ratings for the market.

Shortly before Midnight on July 14, after playing "Only Human" by The Jonas Brothers, KPTT began stunting, playing only music by Britney Spears as "Free Britney Radio", as the stunt took place during her ongoing conservatorship court dispute, the next hearing which would take place that afternoon.

[28] On December 11, 2017, KBPI/Fort Collins began simulcasting the station's active rock format on KPTT-HD2's subchannel and on translator K300CP (107.9 FM) in Denver, which is a relay of KPTT-HD2.
