KNOX broadcast on channel 10 as an ABC affiliate. The station later signed on Winnipeg-targeted border blasterKCND-TV, which was a semi-satellite of KNOX, on November 7, 1960. While KNOX was a primary ABC affiliate, the station also carried programming from NBC.
In 1962, KNOX and KCND, along with KEND-TV (now KVLY-TV) in Fargo, North Dakota, were purchased for $675,200 by the Pembina Broadcasting Company, a group led by Ferris Traylor, the part-owner of an Indiana TV station.[1] KNOX merged with KEND, and KNOX shut down in 1964 after KEND (known as KTHI-TV at this time) began transmitting from a tower in Blanchard, between Fargo and Grand Forks. After KNOX-TV's shutdown, the Grand Forks area did not have a local television station until NBC affiliate WDAZ-TV signed on in 1967.
