(From Wikipedia) KTVF signed on the air in February 1955 as the first television station serving what at the time was the smallest television market in the United States. The station was a CBS affiliate until April 1, 1996. While primarily a CBS station, KTVF also served as secondary affiliates for ABC from 1971 to 1985 (when they aired some of ABC's top-rated shows like Marcus Welby, M.D., Happy Days, Laverne & Shirley, Three's Company, and Eight is Enough as well as Wide World of Sports and the Academy Awards) and NBC from 1985 to 1996.
During the late 1950s, the station was also briefly affiliated with the NTA Film Network. During the Trans-Alaska Pipeline construction boom of the 1970s, KTVF was also the first station in Alaska with an hour-long evening newscast from 5:30-6:30 pm. In 1996, KTVF switched affiliations, from CBS to NBC. The reason for the network switch was that rival station KATN -- which had NBC affiliation since signing on a couple weeks after KTVF but had been primarily with ABC since 1984—would be merged with two other ABC stations in Anchorage and Juneau to form ABC Alaska's SuperStation, and that NBC was the dominant network by the 1995-96 season while CBS was in third place. KTVF also carried UPN programming on the weekends from 1995 to 2000. Fox affiliate KFXF aired a few CBS shows until K13XD signed on in August.
KTVF is currently owned by Chena Broadcasting. Previous owners include Newport Television; Clear Channel Communications; the Ackerley Group; and Northern Television, Inc. Its transmitter is located on Ester Dome.
