"The Oregonian" sold KGW-AM-FM to North Pacific Television, a consortium of Seattle businesswoman Dorothy Bullitt and five Portland businessmen, on November 1, 1953. Bullitt's King Broadcasting Company, who also owned KING-AM-FM-TV in Seattle, was the largest shareholder in the venture, with a 40 percent stake. Bullitt eventually bought out her partners (and in doing so, became the sole owner of the station), and KGW-TV signed on the air on December 15, 1956 on channel 8 as an ABC affiliate. On April 26, 1959, it swapped affiliations with KPTV (channel 12), becoming an NBC affiliate (KGW's sister station, KING-TV in Seattle, also switched from ABC to NBC with KOMO-TV at the same time).
