Abstract
Social media companies wield considerable power over what people can say and do online, with consequences for freedom of expression and participation in digital culture. Yet we still know little about the factors that shape these companies’ policy decisions. Drawing on data collected from mainstream English-language news sources between 2005-2021 and on a novel dataset of policy documents from the Platform Governance Archive (PGA), we investigate the extent to which policy change at Facebook, Twitter, and YouTube is responsive to negative news coverage. We find that sustained negative coverage significantly predicts changes to platforms’ user policies, highlighting the role of public pressure in shaping the governance of online platforms.
