KNCW is a CW affiliate serving East Wenatchee, Wenatchee, Sunnyslope, Chelan, Malaga, Leavenworth, Entiat, Cashmere, Waterville, Rock Island and all of the Twin Counties area of North Central Washington. It broadcasts on channel 48.
KNCW first signed on as a locally-owned station on June 4, 1989 as a station heavily focuses on cartoons, off-network sitcoms, dramas, westerns, sports and fictions. On New Year's Day 1993, the station was sold to Greenwich, Connecticut-based Renaissance Broadcasting. The station was acquired by Tribune Broadcasting following the company's purchase of Renaissance in 1996. A year earlier, KNCW became a charter affiliate of The WB Television Network, half-owned by Tribune, and changed its call letters to KNWB. However, due to preemption to local programming, cable customers could watch the full WB schedule on sister station KTWB-TV (now KZJO-TV) from Seattle.
In Mid-2000, the station swapped affiliations with UPN affiliate and former rival independent station KWEW, and changed its call letters to KWAU.
On September 18, 2006, the day after The WB officially shut down, it became more or less of a charter affiliate of the upstart CW Television Network. Earlier that year, the station changed its call letters to the original KNCW, with the "NCW" standing for "North Central Washington" or unofficially, the "New CW".
On March 31, 2008, KNCW began airing a KPQ-produced 10 p.m. newscast (Q30 CBS News @ Ten on KNCW, now called Q30 News @ Ten on CW 48) Monday through Sunday.
