Savings Building at 1520 Westlake Ave. Kraft sold the station to businessman Adolph Linden in 1928. KJR was planned to be the key station for a new radio network, the American Broadcasting Company (unrelated to the current ABC radio network), with plans for a nationwide expansion. However, the effort failed and Linden and a subsequent owner, Ahira Pierce, were jailed for illegal financing, using money from financial institutions which went bankrupt. KJR was then acquired by NBC, which in 1933 leased the station to the Fisher family-owned Fisher's Blend Station, Inc., owners of KOMO radio, who moved the KJR studios to the Skinner Building. NBC Blue Network In 1936, KJR became an affiliate of the NBC Blue Network. It aired its dramas, comedies, sports and newscasts. This affiliation continued after the Blue Network became ABC in the 1940s. In 1937, a new transmitter was erected on Seattle's West Waterway, which operated until 1996. On March 29, 1941, KJR, along with the other stations on 970 kHz, moved to 1000 kHz, as part of the implementation of the North American Regional Broadcasting Agreement (NARBA). That same day the Fisher family, after leasing the station for eight years, purchased it outright. At that time, KJR was powered at 5,000 watts but it had submitted a construction permit to go up to 50,000 watts. The studios were in the Skinner Building in Seattle. Call letter swap between KJR and KOMO The August 1941 adoption of the Federal Communications Commission's "duopoly" rule restricted licensees from operating more than one radio station in a given market. At this time the Fisher family owned two Seattle stations – KJR on 1000 kHz and KOMO on 950 kHz – and their efforts to be granted an exemption were unsuccessful. The Fishers decided to keep the superior frequency of 1000 kHz, but also keep the KOMO call letters that they had held since the 1920s. Thus, on May 6, 1944, KOMO and KJR swapped call letters, with the KJR call sign moving from 1000 kHz to the less desirable 950 kHz. The next year KJR was sold to Birt F. Fisher, who was unrelated to the KOMO owners. In 1946, KJR was purchased by Marshall Field's Department Store chain. It continued its affiliation with ABC until 1953, when ABC affliliation switched to 1090 KING. In July 1952, Marshall Field sold the station to a group headed by Chicago
