About KTTCWhat is it now? On September 21, 1998, KTTC formed a collaboration with The WB 100+, a nationwide programming service owned by The WB for television markets ranked more than 100, and cable companies in the Rochester region to launch KTTC-DT2. Prior to 1998, Rochester could watch WGN-national TV's feed or local WB station KMWB (now WUCW) in Minneapolis-Saint Paul. It was a cable-only station, thus it used the call letters "KWBR" (for "The WB Rochester") in a fictitious way for identification. KTTC provides local advertising possibilities as well as promotional services for the station.
On January 24, 2006, CBS Corporation (which separated from Viacom in 2005) and Warner Bros. Television (the firm that controlled The WB) announced that they will quit operating the UPN and WB networks and merge their resources to form The CW. The letters would reflect the first initials of the respective corporate parents of the new network.
On September 18, same year, The CW went national, and KTTC introduced a new second digital subchannel to simulcast "KWBR" and provide non-cable subscribers with access to the new network. With its over-the-air debut, "KWBR" adopted the call letters KTTC-DT2 and joined The CW Plus, the successor of The WB 100+.
