About FOX Q13Channel 13 signed on the air on August 2, 1953 as KMO-TV, co-owned with KMO radio (AM 1360, now KKMO). The station was initially owned by Carl Haymond and carried some NBC programming for its first year. However, when Seattle-licensed KOMO-TV (channel 4) began broadcasting on December 11, KMO-TV struggled due to a poor signal from north of Tacoma and a lack of alternative programming sources. As a result, Haymond was forced to declare bankruptcy and sell the station to J. Elroy McCaw, a radio and television station owner and the father of cellular phone magnate Craig McCaw.
KMO-TV was purchased by McCaw in 1955 and changed its call letters to KTVW (standing for "TeleVision Washington") in 1957. In 1986, the station changed its call letters to KSTW (standing for "Seattle Television") after being acquired by the Gaylord Broadcasting Company. In 1995, the station was acquired by CBS, becoming a CBS affiliate. In 1999, the station was acquired by the Tribune Broadcasting Company, becoming a WB affiliate. In 2006, the station was acquired by the CBS Corporation, becoming a CBS affiliate once again.
