King Broadcasting Company is a Seattle, Washington media conglomerate and a subsidiary of Tegna founded by Dorothy Bullitt. It began with one AM radio station and later an FM radio station, and grew to include a large group of broadcast television and radio stations, as well as a cable television network.
In 1946, Dorothy Bullitt purchased Seattle radio station KEVR-AM, 1090. KEVR had no network affiliation and relied entirely on syndicated programming from service providers such as World Transcription Service, MacGregor Transcription Service, and Fredrick W. Ziv Productions.
Thus, KEVR aired programs such as Boston Blackie, The Shadow, The Lone Ranger, and Calling All Cars, programs the big network radio stations did not have. As a result, KEVR offered independent listening choices that maintained a rather large listening audience, the cost, of which, was supported by commercial advertising sponsors. Although not having a network was a tough proposition, under Dorothy Bullitt's guidance, the station prospered.
In the early days, the Ziv Company also furnished syndicated television programming to KING-TV, such as Highway Patrol, starring Broderick Crawford, and Sea Hunt, starring Lloyd Bridges.
Bullitt's radio station later raised is output power to 50,000 watts, the maximum allowed in the United States.
Also in 1947, Bullitt purchased call letters from a fishing boat and changed KEVR to KING.
In 1948, Dorothy Bullitt constructed KING-FM at 98.1 to air classical music, her favorite. In 1949, she purchased KRSC-TV, Channel 5, for $375,000. The call letters of the television station were also changed to KING-TV.
When KRSC-TV first went on the air Thanksgiving Day, November 25, 1948 under other ownership, it was the only television station west of Minneapolis and north of San Francisco. At that time, many considered television a fad and passing fancy. Consequently, making a go of a television station during this time period was a daunting effort.
