Mediated Communities brings together a diverse, global cohort of academics and professional communicators to assess the current state of democratic mobilizing around the world and the ways in which protest movements are being transformed in the midst of a communication revolution. Contributors draw on a variety of international settings – from Greece to Lebanon, China to Argentina – to demonstrate the ways in which community organizing in the digital age relies increasingly on digital media to communicate, help participants find common ground, and fight for change. Contributors acknowledge the challenges that lie ahead for creating real and lasting democratic change, but at the same time are able to draw attention to the potential that digital media hold for strengthening citizen voices around the globe.
