WBBM-TV

==WBKB-TV==
===1946–1949===
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. 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.

On April 25, 1953, United Paramount Theaters merged with the American Broadcasting Company (ABC), which already owned WENR-TV (channel 7). As the newly merged entity could not keep both stations since FCC regulations forbade the common ownership of two television stations licensed to the same market, WBKB was sold to CBS for $6.75 million. Back on February 12, one day after the merger was finalized, the station changed its call letters to WBBM-TV, after WBBM radio (AM 780 and FM 96.3), which CBS had owned since 1929. The WBKB call letters were subsequently assumed by channel 7 (that station would eventually change its callsign to WLS-TV in 1968, and the callsign now resides at a CBS-affiliated station in Alpena, Michigan).
===1953–1956===
On July 5 of the same year, WBBM-TV moved to Channel 2 in order to alleviate interference with WHBF-TV in Quad Cities, and WTMJ-TV in Milwaukee which six days later moved from Channel 3, concluding the transmission of Chicago's channel 4.
