On January 24, 2006, CBS Corporation and Time Warner announced that The WB and UPN would cease broadcasting that September and merge their programming to form a new "fifth" network called The CW. The letters represent the first initials of its corporate parents, CBS (the parent company of UPN) and the Warner Bros. Entertainment unit of Time Warner. In April 2006, KXVO announced an affiliation agreement with The CW, which began airing on the station when the network launched on September 18 of that year.
