KWBL (106.7 MHz) is a commercial FM radio station licensed to Denver, Colorado. It is owned by iHeartMedia and it broadcasts a Country music format branded as 106.7 The Bull. KWBL carries two nationally syndicated country music shows from co-owned Premiere Networks: The Bobby Bones Show on weekday mornings and CMT Nites with Cody Alan heard overnight. The radio studios are located in the Denver Tech Center.

KWBL has an effective radiated power (ERP) of 100,000 watts. The transmitter is on Lookout Mountain in Golden, amid the towers for other Denver-area FM and TV stations.[1] KWBL broadcasts using HD Radio technology. Its HD-2 digital subchannel carries the iHeartRadio soft adult contemporary music service known as "The Breeze."


106.7 FM signed the air on June 19, 1962, as KLZ-FM. Initially airing a simulcast of their then-AM sister station, it flipped to a rock format in the early 1970s. In 1977, KLZ-FM changed their call letters to KAZY (now at 93.7 FM in Cheyenne, Wyoming) and continued with a rock format until April 20, 1994, when KBPI took over the 106.7 frequency, moving from 105.9 (now KALC).[2]

In December 2017, iHeartMedia re-aligned multiple stations in the Denver, Colorado Springs, Fort Collins, and Cheyenne markets in order to form a trimulcast (which was later split up on January 28, 2019) of KBPI on the 107.9 frequency. To facilitate the move for the main signal, on the 1st, KYWY (an adult contemporary station in Cheyenne, Wyoming, which was acquired by iHeart in 2016)[3][4] moved its existing format to an HD Radio subchannel of KOLT-FM and its analog translator on 97.1, allowing KPAW to move its classic rock format and call letters to the 92.9 signal four days later. On the 11th, KBPI then moved its format and call letters to KPAW and translator K300CP, while also adding a simulcast on KDZA-FM. The KYWY calls were warehoused on the former 106.7 signal; iHeart stated that the station would temporarily simulcast KBPI through the end of the year, and be re-launched with a new format after the end of the simulcast period.[5]

On December 18, 2017, at 5 p.m., KYWY dropped out of the simulcast and, following a 10-minute stunt montage of random TV and movie audio clips backed by a ticking clock, flipped to country music as 106.7 The Bull, launching with a 10,000 song commercial-free marathon, starting with "Body Like a Back Road" by Sam Hunt. The flip gave long-time country stalwart KYGO its first full-market competition since that station flipped to the format in 1979, while also competing with KWOF, which rimshots the market from the north (KWOF later flipped to sports talk in 2018 after its sale to Kroenke Sports & Entertainment).[6] On December 26, 2017, KYWY changed its call letters to KWBL to match its new branding.[7]
