The station originally signed on the air in January 1989 as KKVI, operating as a satellite station of PocatelloABC affiliate KPVI; it also carried Fox as a secondary affiliation during the late evening hours. This arrangement ended when KPVI ended its ABC affiliation to become an NBC affiliate in 1996. KKVI could not operate as an NBC affiliate because the network's Boise affiliate KTVB provided NBC network programming to Twin Falls via a low-powerbroadcast translator. The station then chose to switch to Fox full-time.
