The document discusses the role of social media in social protests in Brazil. It analyzes two case studies: the Clean Slate campaign of 2008-2010 and the nationwide protests of 2013. For the Clean Slate campaign, social media helped gather over 2 million signatures online and engage thousands of supporters. The 2013 protests erupted over public transportation fare hikes and used hashtags on Twitter to coordinate demonstrations in major cities across Brazil, exerting pressure that led to some policy changes addressing citizen demands. Social media has allowed social movements to organize more cost-effectively and given citizens new ways to participate politically both online and offline.
