It was owned by the Samsung Group founder Lee Byung-chul and was a sister company to the JoongAng Ilbo.

According to the article, Tongyang TV Broadcasting Co., Ltd. was ready to transmit radio waves using purely Korean technology, having secured three cameras and one relay vehicle, and applied before the Korean government for broadcasting frequencies.

In January of the following year, it was reported that it was scheduled to establish in May by being assigned channel 7 with permission from the authorities.

At that time, the government showed willingness to produce TV receivers and transmitters in Korea, except for parts that could not be manufactured, and the first TV cameras from Tongyang Broadcasting Station were also produced by combining movie cameras and used devices.

TBC took the upper hand in producing prerecorded dramas, something KBS hadn't achieved at the time.

In the case of Tongyang TV's Busan branch, it is impossible to broadcast a direct signal from Seoul (simultaneous transmission) due to the absence of microwaves, focusing on local programs in Busan, Ulsan, and Gyeongsangnam-do.

Here it is… 630… Old kilohertz… HLKC… This is… Tongyang Broadcasting..."[14]In November 1980, Tongyang Broadcasting was forced to merge with KBS at 00:00 on December 1, 1980, following the media consolidation measures carried out by Heo Mun-do after the 12.12 incident and the military forces came into power.

At the time of the merger and acquisition, Tongyang Broadcasting's assets amounted to 34 billion won.

On November 26, 1990, JoongAng Ilbo submitted an application for compensation to the Seoul District Prosecutors 'Office of Seoul District Prosecutors' Office to pay compensation of KRW 860 billion for damages incurred from the forced transfer of Tongyang Broadcasting to the Korean Broadcasting System and the state.

The committee rejected 14 companies including the JoongAng Ilbo for compensation for damages after three years of lapse.

On November 30, 2009, 19 years later, about 400 people, including former TBC officials and entertainers, held a 'Prayer for the Restoration of Tongyang Broadcasting' and adopted the resolution to encourage JoongAng Ilbo to advance into the general entertainment channel business.

The JoongAng Ilbo insisted that its long-term JTBC was the successor to TBC before the Korea Communications Commission's selection process for the generalist channel, and was closed on November 30, 1980.
