History
In the early 1950s, commercial broadcasters began to appear throughout Japan. On February 20, 1953, Yamagata Broadcasting held its first founders' meeting, and Yamagata Shimbun, a local newspaper, had an important role in the establishment of Yamagata Broadcasting, as did most of the first commercial broadcasters in Japan. At that time, the head office of Yamagata Broadcasting was located in Yamagata Shimbun with a capital of 50 million yen.[1]: 4–5
On March 14 of the same year, Yamagata Broadcasting applied to the Ministry of Post and Post for a broadcasting license,[1]: 8–9 and obtained a preliminary license on August 14 of the same year.[1]: 12–13 However, Yamagata Broadcasting was facing a shortage of funds at that time, so the president of Yamagata Shimbun, Hattori Keio, requested the Yamagata Prefectural Government to fund Yamagata Broadcasting, and finally got the agreement.[1]: 18–19 On September 26, 1953, Yamagata Radio began to transmit experimental radio signals.[1]: 25–26 On October 5 of the same year, Yamagata Broadcasting received a formal broadcast license.[1]: 26–27 The next day, Yamagata Broadcasting Station started trial broadcast.[1]: 27–28

On July 29, 1959, construction began on the Yamagata Shimbun Broadcasting Hall, a new joint headquarters building for both companies. This building has six floors and has a 53-meter-high TV tower on the roof.
