From the social media-based 2008 Obama election campaign to the civic protest and political revolutions of the 2011 Arab Spring, the past few years have been marked by a widespread and complex shift in the political landscape, as the rise of participatory platforms- such as YouTube, Twitter, Facebook, and blogs- have multiplied the venues for political communication and activism. This book explores the emergence of a permanent campaign- the need for constant readiness- on networked communication platforms. With in-depth analyses of some of the most well-known participatory media today, this book offers a critical assessment of the constant efforts at managing the plurality of voices that characterize contemporary politics. -- from Publisher description.
