In 1958, KXLF-TV and KXLJ-TV, in association with KFBB-TV in Great Falls, KOOK-TV in Billings (now KTVQ), KID-TV in Idaho Falls, Idaho (now KIDK), and KLIX-TV in Twin Falls, Idaho (now KMVT), formed the Skyline Network. KFBB was later replaced by Great Falls' other station, KRTV. Later that year, the station added a secondary affiliation with CBS; by 1960, CBS was the station's primary network, though NBC was retained on a secondary basis. That year, Craney sold KXLF-AM-TV, along with KXLJ-AM-TV in Helena, to Joe Sample, president of Garryowen Corporation and owner of KOOK-TV, for over $1 million—earning a handsome return on his original investment in KXLF radio in 1929. Sample immediately spun the KXLJ stations off to Helena Television; KXLJ-TV (which was renamed KBLL-TV) eventually severed its ties with KXLF and left the Skyline Network.
