KHON-TV
On October 23, 2006, KHON-TV was announced as the Honolulu affiliate of The CW, carrying the network on its second digital subchannel. Beginning in March 2006 (two months after the network's launch was announced), The CW had struggled to find an affiliate in Honolulu after the market's then-WB affiliate KFVE, which was seen by many as the likeliest candidate to join The CW, signed with competing network MyNetworkTV, and former UPN affiliate KIKU (which aired the network's programming in the afternoons) declined to take the CW affiliation.
KRON-TV
On February 22, 2006, News Corporation announced the launch of MyNetworkTV; the network was created partly in response to CBS Corporation and Time Warner's January 24 announcement that UPN and The WB would be shut down and replaced with the jointly-owned CW Television Network (CBS-owned UPN affiliate KBHK, whose callsign became KBCW by the network's launch, was named The CW's Bay Area affiliate; WB affiliate KBWB became an independent station). KRON-TV became a MyNetworkTV affiliate when it debuted on September 5, 2006 (it is currently one of the largest MyNetworkTV-affiliated stations not to previously have been an affiliate of either The WB or UPN, second only to the network's Dallas O&O KDFI). The station began branding itself as ""MyKRON 4"" for MyNetworkTV programming, although it continues to promote itself as ""KRON 4"" outside of the service's programming hours. After joining MyNetworkTV, the station moved its hour-long 9 p.m. newscast to 8 p.m., opting to run the fledgling network's programming from 9 to 11 p.m. (one hour later than MyNetworkTV's standard 8 to 10 p.m. scheduling in the Pacific Time Zone).
