 By the summer of 1969, CBS programming exceeded that of NBC, which meant that KRTV was now a primary affiliate of CBS—and still is.The station became a full-time CBS affiliate in 1976, when KTCM (now KTVH) expanded its coverage to become (until 1986) the default NBC affiliate in a large part of Montana, including Great Falls.In 2005, KRTV took over the operations of KXLH in Helena, which had previously been a semi-satellite of KXLF-TV in Butte.
