Cyberactivism already has a rich history, but over the past decade the participatory web—with its de-centralized information/media sharing, portability, storage capacity, and user-generated content—has reshaped political and social change. Cyberactivism on the Participatory Web examines the impact of these new technologies on political organizing and protest across the political spectrum, from the Arab Spring to artists to far-right groups. Linking new information and communication technologies to possibilities for solidarity and action—as well as surveillance and control—in a context of global capital flow, war, and environmental crisis, the contributors to this volume provide nuanced analyses of the dramatic transformations in media, citizenship, and social movements taking place today.
