When Taiwanese government introduced "product placement", to promote their policies in news reporting since 2002, it became a highly debatable issue. This article explores the concept of the "public interest" by first referring to the conflict of public interest and product placement. Amid the complex environment of conflicting interests, this article attempts to propose a framework for the public and the media to participate in creating the public interest. Meanwhile, this article stresses two points: (1) "Public interest" should be based on public, rational and plural communication, any attempt to "place" private interest in news will violate the value of public interest. (2) News reporting for "public interest" should be based on professional values: independency, autonomy and responsibility. The placed news functions to manipulate journalist profession. Without being able to do independent and autonomous news reports, how can we expect the news to fulfill public interests? Any media organizations that accept "product placement" would gain profit but lose credibility in return.
