Bringing together contributions from the fields of sociology, media and cultural studies, arts, politics, science and technology studies, political communication theory and popular culture studies, this volume engages both with theoretical debates and detailed empirical studies, showcasing how the public sphere is transformed by digital media, and in turn how this digital public sphere shapes and is shaped by debates surrounding crisis, conflict, migration and culture. Case studies from Bulgaria, Nigeria, China, Greece, Italy, Cyprus, UK, Mexico and India are discussed in detail.
