On January 24, 2006, CBS Corporation (which split from Viacom in December 2005) and Time Warner's Warner Bros. Entertainment (the division that operated The WB) announced that the two companies would shut down The WB and UPN and combine the networks' respective programming to create a new "fifth" network called The CW. One month later on February 22, News Corporation announced the launch of a new "sixth" network called MyNetworkTV, which would be operated by Fox Television Stations and its syndication division Twentieth Television. KTPN and KLPN became charter affiliates of MyNetworkTV when the network launched on September 5, 2006; KCEB took the CW affiliation when the network launched two weeks later on September 18 (The CW Plus feed carried by the station has since moved to KYTX's second digital subchannel).
