In the past decade, there has been a fruitful result on the theme of the history of Taiwan broadcasting enterprise during the Japanese colonial era. In this article, the author will use the newly published documents to explore more thoroughly contour about the Taiwan Broadcasting Association (TBA in abbreviation), including their organizational structure, financial conditions and personnel character. The listener and radio receiver are the other two important factors that cannot be deviated from the broadcasting enterprise. Our first major finding is that the Japanese proper and the colonial government alike, at the very beginning, recognized that the radio waves were scarce resources and should be monopolized by government. This monopolization characters were also reflect on the program fabrication. In order to fit the official propaganda, assimilation was the main theme in the program. The restriction on using the Taiwanese language also obstructs the opportunity for Taiwanese to intimate this modern instrument. The ever-extending high price on radio receivers led the market to be urban-merchant bias, especially in Northern Taiwan. Focusing on the Taiwanese audience, the radio market polarized between the most par and the highest price, which also hedge about developing the of radio market through commercialization and gave chance for the TBA to monopolize the countryside market. During the Japanese colonial era, the possession and distribution of radio waves, the construction of broadcasting enterprise, and even on the production and marketing on the radio receivers, the colonial government appropriated every facet of the broadcasting resources. The state-monopolization was, by and large, the basic characteristic of Taiwan broadcasting history in its initial stage.
