WMHX was taken off-the-air. Two years later, the station returned to the air as WMHQ, carrying a large amount of instructional programming alongside repeats and double runs from WMHT. Further financial difficulties at WMHT led to WMHQ being put up for sale in the late 1990s. Despite WMHT's financial difficulties, WMHQ's commercial license was still very valuable. By this time, the Capital District had grown large enough that a second non-Big Three station was now viable. After a sale to Sinclair Broadcast Group, which intended to make the station a dual UPN/WB affiliate, fell through, Tribune Broadcasting, part-owner of The WB, bought the station in 1999 for $18.5 million. Channel 45's final day of programming as a PBS station was September 5, 1999; after its nightly midnight sign-off, it returned to the air at 6:00 a.m. the next morning as WB affiliate WEWB-TV, branded on-air as "WB 45". Prior to WEWB's relaunch, WPIX and WGN-TV's national feed had both served as the default WB affiliates for the Capital District. WPIX remained available to cable viewers in Albany until 2002, but was blacked out during WB programming as well as syndicated programming shown exclusively on Albany stations (due to syndication exclusivity rules). From the station's relaunch as WEWB until December 2006, its master control was located at sister station WB affiliate WLVI-TV in Boston. However, local offices were at Corporate Woods in Albany. WLVI's meteorologists maintained WCWN's weather page. In 2004, WEWB's digital signal signed on-the-air and began broadcasting on UHF channel 43. In 2005, the "WB 45" name was dropped in favor of "Capital Region's WB" at the tail end of a period in which most of Tribune's WB affiliates (minus its VHF and "heritage" stations) were re-branded in the same format. Eleven years after the births of UPN and The WB on January 24, 2006, it was announced by CBS and Time Warner that The WB would merge with its rival network, UPN, to form The CW. As part of the deal, the newly formed network signed a 10-year affiliation deal with 16 of Tribune's WB stations, including WEWB. In preparation, the station's call letters changed to the current WCWN on May 10. In July 2006, commercials for The CW as well as syndicated fall programming had the station rebranding as "The Capital Region's CW" effective with the network's launch on September 18. On June 19, 2006, Tribune announced
