#JusticeforGeorgeFloyd: How Instagram Facilitated the 2020 Black Lives Matter Protests
We present and analyze 1.13 million public Instagram posts during the Black Lives Matter protests of 2020, which erupted in response to George Floyd’s public murder by police on May 25. Our aim is to understand the growing role of visual media, through a comprehensive view of the spatial (where) and temporal (when) dynamics, the visual and textual content (what), and the user communities (who) that drove the social movement. Using network and time-series analysis, results reveal New York, California, and Minnesota evolved as the epicenters of online social interaction. Our results also make two theoretical contributions. Social movements traditionally typologize posts as discrete instances of mobilization, organization, or conversation. The semantic analysis of 1.69 million photos show these functions are folded together visually. Second, we discuss how pre-existing meme groups and international organizations stood in solidarity to critically assist information dissemination. Together, these analyses demonstrate the precarious nature of protest journalism, and how international content creators, journalists, and everyday users co-evolved with social media to report on one of America’s largest-ever human rights movements.
