After the Asia-Pacific war, commercial broadcasting networks developed, formed from program-trading relationships based on key stations. The purpose of this article is to study the basic structure of program-trading relationships by focusing on the selection of core stations which were the focus of program trading by local stations. Decisions about program-trading relationships were influenced by government regulation policies and other factors. These factors prescribed decisions about the network relationships in each allocated area. Meanwhile, the ability of key stations to produce programs became the main factor in the progress of program trading outside network relationships. However, this function of key stations only lasted until the establishment of the basic structure of the program-trading relationships. As we see in the example of the reorganization of program-trading relationships in the Fukuoka-Kitakyushu area, with the gradual establishment of program trading, the advantages and the disadvantages of the situation became clear, leading to the next step in the development of program-trading relationships.
