The power of activist networks in the mass self-communication era: A triangulation study of the impact of WikiLeaks on the stock value of Bank of America

This case study examines a confrontation between WikiLeaks and Bank of America (BOA). Drawing upon Castells’ concept of mass self-communication and the cocreational approach to public relations, a triangulation of social network analysis and event study method allows this project to capture the structure of WikiLeaks’ global network and to document how the activist network affected BOA's stock value. The analysis reveals that WikiLeaks emerged as the center of a global mass self-communication network consisting of a diverse group of members, such as social media sites and mass media outlets. The study offers implications for a re-conceptualization of the role of activism in public relations.
