KOOK Radio 970 came on the air March 20, 1951 in Billings, Montana. The station underwent several call number and format changes until April 17, 1998, when the call letters were changed to KBUL "The Bull", broadcasting a country format. On September 10, 2001, the format was changed to all news, just one day before the terrorist attacks occurred on September 11, 2001. The KBUL call letters remain, but now refer to "The Bulletin" and the station features such radio personalities as Rush Limbaugh, Glenn Beck and Sean Hannity.
