WGEM-DT2 is the CW-affiliated television station for the Tri-States area of Western Illinois, Northeastern Missouri, and extreme Southeastern Iowa. The station is part of The CW Plus, a special CW feed that broadcasts on cable and / or over-the-air on a digital signal. It is a second digital subchannel of NBC affiliate WGEM-TV which is the flagship of Quincy Newspapers. Over-the-air, WGEM-DT2 broadcasts a digital signal on VHF channel 10.2 from a transmitter east of Quincy, Illinois on Cannonball Road near I-172. Known on-air as Tri-State's CW, this can also be seen on Comcast channel 6 in Illinois, US Cable channel 16 in Missouri, and Mediacom channel 18 in Iowa. WGEM-DT2's parent station has studios in the Hotel Quincy on Hampshire Street in Downtown Quincy.
WGEM-DT2 began broadcasting as a WB affiliate. It was a cable-only station, and as a result, had the fictional call letters "WEWB". The station was part of The WB 100+ group. Current CW affiliate WCWN in Albany, New York held the actual WEWB call sign when it was a WB affiliate. Following the 2006 merger of UPN and the WB, WEWB, now on WGEM-DT2, began airing programming from the CW. The station became part of The CW Plus, a service that is a similar operation to The WB 100+. Like all CW Plus affiliates in the Central Time Zone, WGEM-DT2 airs the nationally syndicated morning show The Daily Buzz on weekdays from 5 to 8.
