At first KFBB-TV was owned by Wilkins Broadcasting along with KFBB radio (1310 AM, now KEIN), of which The Anaconda Company owned a 27.5% share. Anaconda, through its Fairmount division, controlled most of the major newspapers in Montana (although not the "Great Falls Tribune") and was notorious for manipulating the state's political visions for its own needs. Then in 1959, Anaconda sold its media holdings to Lee Enterprises of Davenport, Iowa. Because of anti-trust concerns, Lee decided to sell KFBB. The station was sold in 1962 to Harriscope Broadcasting, which in 1965 scored a deal for a primary ABC affiliation—Montana's first. The new affiliation took effect on February 1, 1966. Harriscope severed KFBB's links with the Skyline Network (which signed up with KRTV), and sold off KFBB radio in February 1969, but continued to run KFBB-TV, eventually selling it to Donald P. Nathanson in 1977. After affiliating primarily with ABC, the station continued secondary affiliation with CBS until that network switched to KRTV in 1969, and then started running NBC on a per program basis as late as December 1986, when KTGF (now KJJC-TV) signed on and took over the NBC affiliation. KFBB also carried "Sesame Street" for several years, before Montana had a PBS service of its own.
