In 1977, KLZ-FM changed their call letters to KAZY (now at 93.7 FM in Cheyenne, Wyoming) and continued with a mainstream rock format.

On March 19, 1996, KBPI made national headlines following the suspension of three of the station's disc jockeys, Joey Teenan, Dean Meyers, and Roger Beatty, after the station was interrupted by two of its disc jockeys, Meyers and Beatty, breaking into mosques and playing "The Star-Spangled Banner" with a trumpet and a bugle blaring loud during its morning show, while the third jockey, Teenan, wore a turban and an Abdul Rauf shirt during a "Torture Tuesday" segment.

Station manager Jack Evans called the stunt "an ill-conceived attempt at humor" and replied on the segment being "judgemental".

[7] 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.
