The document discusses research on media framing of the 2013 protests in Brazil. It presents hypotheses that the more people participate in protests, the more legitimizing frames the media will use (H1). Additionally, the broader the collective action frames of the protests, the more legitimizing frames will be used (H2). The study uses computerized content analysis of news websites, blogs, and Twitter to analyze frames over time. Preliminary results suggest the media initially used more confrontational frames but shifted to more legitimizing frames as protest participation and resonance of rights-based frames increased, supporting H1 and H2. Future research is needed comparing media frames to collective action frames used by social movement organizations.
