"This book examines three aspects of the use of social media for political activism: the degrees of media freedom practiced in countries around the world; the methods by which governments attempt to block access to information; and the various ways in which activists use the media-especially social media-to advance their cause of greater freedoms. Readers will learn how these political uprisings came from the grassroots efforts of oppressed and unhappy citizens desperate to make better lives for themselves and others like them-and how the digital age is allowing them to protest and call attention to their plights in unprecedented ways."
