This document discusses transmedia activism and its use of storytelling across multiple platforms to create social impact. Transmedia activism allows for decentralized authors to share assets and create entry points into issues to build community. It provides a framework to use narrative and social action to raise issue awareness, engage communities, inspire action and create change. By collectivizing ownership of narrative, transmedia activism breaks down barriers and allows people to work together towards social challenges. Examples provided examine using local voice and arts to reconnect audiences with causes and motivate advocacy or action. Risks include intellectual property concerns, technology over substance, and ensuring narratives respect community perspectives.
