"In the field of citizen media research, considerably less attention has been paid to countries other than the US and those in Western Europe. This article is a case study that focuses on citizen media in Beijing – specifically, the Dazhalan [participatory video] project. Combining in-depth interviews and textual analysis, the article demonstrates the uniqueness of citizen media under China’s state-party media system. The article also suggests that it was the collaboration among ordinary citizens, professionals and journalists that made it possible for citizen media to influence the mainstream media frame-building process."
