WLS-TV

WLS-TV is the ABC owned-and-operated television station in Chicago, Illinois. It broadcasts a high definition digital signal on UHF channel 44 (virtual channel 7.1 via PSIP) and operates a digital fill-in translator on VHF channel 7, both from transmitters atop the Willis Tower. Owned by the ABC Owned Television Stations unit of The Walt Disney Company, WLS-TV maintains studios on North State Street in the Chicago Loop. The WLS-TV callsign stands for "World's Largest Store", in reference to Sears, Roebuck and Company, the founding part-owners of its former AM radio sister station.
