Book excerpt: The intersection of virtual and physical spaces at the heart of contemporary political protests is a pivotal element in new practices of activism. In this new and global ecology of dissent and activism, different forces, stakeholders, and spaces, once defiantly discordant, come together to define the increasingly malleable nature and terms of participatory politics and the performance of democracy. This book explores the emerging sites, aesthetics and politics of contemporary dissent as a critical attempt to foreground their mediation and negotiation in an era of neoliberal globalization. Contemporary forms of media activism occupy deeply ambivalent spaces, which Ardizzoni analyzes using the lens of what she calls "matrix activism." Rather than confining the analysis to a single platform, a single technology, or a single social actor, matrix activism allows us to explain the hybrid nature of new forms of dissent and resistance, as they are located at the intersection of alternative and mainstream, non-profit and corporate, individual and social, production and consumption, online and offline.
