WICS is the ABC-affiliated television station for Springfield/Decatur, Illinois. It broadcasts a high definition digital signal on UHF channel 42 (or virtual channel 20.1 via PSIP) from a transmitter, in unincorporated Sangamon County, south of Dawson and I-72/U.S. 36. Owned by the Sinclair Broadcast Group, the station operates Fox affiliate WRSP (its semi-satellite, WCCU) as well as CW outlet WBUI (all owned by GOCOM Media, LLC) through joint sales and shared services agreements. All of the stations share studios together on East Cook Street in Springfield's Eastside. However, WBUI also operates an advertising sales office on South Main Street/U.S. 51 in Downtown Decatur.
WICD in Champaign/Urbana operates as a full-time satellite of WICS to serve the eastern portion of the market. WICD airs the same broadcast schedule as its parent station but features separate legal identifications and local commercial inserts. Although the station maintains its own studios on South Country Fair Drive in Downtown Champaign, master control and most internal operations are based within WICS' facilities. WCCU's advertising sales operation is based out of WICD's studios.
