Trott interrogates how feminist activists navigate complex technological ecosystems to build awareness of misogyny, violence against women, and oppressive experiences women face both online and offline while cultivating transnational feminist networks and carving out spaces upon which to build and elevate women's voices. This book is guided by a few key questions: how is feminist activism transforming and being mutually shaped by a dynamic and volatile platform ecosystem? How are activists attempting to negotiate this terrain? And, how are (anti)feminist politics contested within the platform society? These questions are addressed through analysis of three key case studies: the international feminist organisation Hollaback!; the #EndViolenceAgainstWomen campaign; and the global #TakeDownJulienBlanc movement. Building on the intersecting fields of feminist media studies, platform and internet research, and political communication, this book addresses cultural and social questions about how digital platforms shape the values of our communities and how stakeholders negotiate and engage in civic practices. This timely and important work interweaves activist discourses, women's voices and scholarly literature together to provide insight into the realities of operating within a platform society. It will be of interest to students and scholars of journalism, gender studies, media and communication studies, culture studies, and sociology.
