 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.
