From Tolkien to Star Trek, from Game of Thrones to Battlestar Galactica, and from The Walking Dead to Janelle Monáe’s Afrofuturist concept albums, transmedia world-building offers us complex and immersive environments beyond capitalism. This book examines the ways in which these popular storyworlds offer tools for anticapitalist theory and practice. Building on Hardt and Negri’s theory of global capitalism, Science Fiction, Fantasy, and Politics shows how transmedia world-building has the potential of offering more than a momentary escape from capitalist realism in the age of media convergence and participatory culture.
