WBBM, 780 AM, is an all-news radio station located in Chicago, Illinois, United States. The station is owned by the CBS Radio division of CBS Corporation. The station's studios are located in the combined CBS Radio facility at Two Prudential Plaza in the Loop neighborhood, and its transmitter is located in Itasca. WBBM is a Class A station which broadcasts on a clear-channel AM frequency. Its daytime signal provides at least grade B coverage to large portions of Illinois, Wisconsin, Iowa, Michigan and Indiana and has been heard as far south as Cincinnati during the day, and city-grade coverage as far north as Milwaukee. At night, it covers much of the eastern half of North America, but is strongest in the Midwest. WBBM is an owned and operated station of the CBS Radio Network.
Since August 1, 2011, much of WBBM's programming has been simulcast over sister station WCFS-FM (105.9). The FM station's call letters were retained and should not be confused with 96.3 WBBM-FM, a CHR/Top 40 station; WCFS's former adult contemporary format was retained in an automated form over its 105.9 HD2 subchannel. WBBM's format is available both in AM and FM with HD Radio.
