At the end of the 20th century, as one of the important news sources, whistle-blower was embedded into the process of news production and became the de facto “journalistic activity subject”. However, whistle-blowers were scattered at that time. Based on the field observations conducted in some large and medium-sized cities, whistle-blowers have been more professional. They co-existed with institutionalized news media in a more organized, specialized and intensive manner. Under such a circumstance, whistle-blowers have been transforming from the news source to the communicator as well as the receiver controlled by the dominant subject.
