CBS Chicago

WBBM-TV (channel 2) is a television station in Chicago, Illinois, United States, serving as the market's CBS network outlet. Owned and operated by the network's CBS News and Stations division, the station maintains studios on West Washington Street in the Loop, and its transmitter is located atop the Willis Tower. History Early history (1940–1953) WBBM-TV traces its history to 1940 when Balaban and Katz, a subsidiary of Paramount Pictures, signed on experimental station W9XBK, the first all-electronic television facility in Chicago. Balaban and Katz was already well known for owning several movie theaters in the Chicago area. In order to establish the station, the company hired television pioneer William C. "Bill" Eddy away from RCA's experimental station W2XBS in New York City. When World War II began, Eddy used the W9XBK facilities as a prototype school for training Navy electronics technicians. While operating the Navy school, Eddy continued to lead W9XBK and wrote a book that defined commercial television for many years. On September 6, 1946, the station received a commercial license as WBKB (for Balaban and Katz Broadcasting) on VHF channel 4, becoming the first commercial station located outside the Eastern Time Zone; it was also the sixth commercial TV station in the United States behind WNBT (now WNBC), WCBW (now WCBS-TV), WABD (now WNYW) all in New York City; WRGB in Schenectady, New York; and WPTZ (now KYW-TV) in Philadelphia. WBKB aired some of the earliest CBS programs, including the 1947 debut of Junior Jamboree (later renamed Kukla, Fran and Ollie after it moved to NBC in 1948). Channel 4 originally operated as an independent station, since at the time it was not clear that it would be an affiliate of either CBS or the DuMont Television Network; eventually, KSD-TV (now KSDK) in St. Louis became the first television station west of the Eastern Time Zone to affiliate with a major network. One of the station's early highlights was its telecast of the National Football League's championship game between the Chicago Cardinals and the Philadelphia Eagles on December 28, 1947.
