This book rethinks the public, public communication and public action in a globalising and mediated world. It develops novel theoretical perspectives for investigating the formation of publics, focusing on four overlapping processes: claiming publics; personalising publics; mediating publics; and becoming public. Using fascinating case studies, Rethinking the public offers a rich set of methodological resources on which other researchers can draw and foregrounds the need to interrogate the boundaries between theory, research and politics. It is ideal reading for higher level undergraduate and masters programmes in politics, geography, public policy, sociology, social policy, public administration and cultural studies.
