Mobilization by images: TV screen and mediated instant grievances in the Umbrella Movement

This article discusses the effects of the televised images of the use of tear gas on people participating in the Umbrella Movement. Although the role of the Internet and social media in political mobilization has been widely discussed, the importance of television cannot be overlooked. This article argues that the widely transmitted broadcasts of live images of the police firing tear gas into the protesting crowd generated “mediated instant grievances” in a substantial sector of the viewing public, thus contributing to the size and scale of the Umbrella Movement. The study reported here provides evidence for this argument by analyzing the results of a survey of protesters that were on site during the early stage of the movement (N = 969). The study sought to determine whether and how the television images were related to the participants’ political attitudes, reasons for participation, and views of self-mobilized actions. The findings showed that, in particular, mediated instant grievances motivated the participation of the “amateur protesters” in the movement.
