KBPI (107.9 FM, "KBPI") is a commercial radio station licensed to Fort Collins, Colorado. It is owned by iHeartMedia and it broadcasts an Active rock radio format. KBPI's studios are located in Denver in the Tech Center. In December 2017, iHeartMedia assembled a trimulcast of KBPI along the Interstate 25 corridor on the 107.9 frequency, by moving KBPI's main signal to 107.9 in Fort Collins, as well as to translator station K300CP in Denver, and switching KDZA in Pueblo/Colorado Springs to a simulcast of KBPI. History KBPI started at 105.9 MHz in Denver on June 21, 1965. It had studios on the 20th floor of the Daniels & Fisher Tower in downtown Denver. The owner and general manager of the station was Bill Pierson, who named KBPI for "Bill Pierson Incorporated." The station featured a progressive rock format. Pierson sold the station in 1974. The station continued its rock format under the new owner, Progressive Broadcasters, Incorporated. During the 1970s and 1980s, the station moved to an album-oriented rock (AOR) sound. Its television commercials featured a blonde woman lip synching with bits of popular Rock songs and DJ's voices, and the tagline KBPI Rocks the Rockies! (elongated with rolling R sounds). This catchphrase is still used in advertising and for a while the campaign was used at other rock radio stations in the United States and Canada. The "blonde woman" AKA "KBPI's Remarkable Mouth" was Kelly Harmon, sister of actor Mark Harmon. During the 1970s, KBPI gained press for inviting people to bring their disco records to the station office for destruction, and this was frequently broadcast live over the air to the tune of Black Sabbath songs. This was commonplace among AOR stations who were riding the anti-Disco theme at the time. For four years, Steven B. and the Hawk ruled the Denver morning FM ratings, mixing rock music with their witty comments and routines. As they put it, "It really didn't matter what kind of music they played. Listeners tuned in to hear them." Their comedic style was highlighted by a self-deprecating sense of humor, rather than "shock jock talk." The duo ridiculed the entertainment industry, regularly parodying movie and TV stars. One of their favorite routines was an ongoing spoof of soap operas. They created their own ongoing series, whose titles were partially taken from the real shows that aired at the time: Edge of Guiding Days
