After mid 80*s, the scholars in the States reveals the basic change of the journalism according to the evidences supported by their research.They found that the value of news and the forms of reporting defined by the traditional craft norms had been substituted by the journalism which emphasize serving the marketplace.
This kind of market force is also the market driven journalism. The market force based on the audience, news and circulation/ rating was replaced by the concept of consumer, product and market. The main point of view of the market driven journalism connects the procedure of the journal by the theory of social transaction ofthe microeconomics.
The market force is so obscure that it is more manipulating, and this is what the scholars of Frankfurt school criticize how the western capitalists run their commercial media as "Cultural Industry". This research hopes to show the actual process of a news issue before it is plotted by the media source, and the relationship between the media source and the news itself by a case study in order to state carefully the truth of the news being manipulated by the industry.
The conclusion of this research shows the reverse relations of the media firms and the journal media because of the excellent technique of the plotting the news by the media firms and the lack of independence of the journalist media. We can also find out that the "news source" becomes a "mechanism", but not a particular person or a spokesman under the mode of commercialized media. This study also comes to the conclusion that the news media and the scholars should discuss how to maintain the journal quality and the interest of the readers and audience.
