Media technologies for play have become major industries in Japan and South Korea. Even in North Korea, citizens bypass the state to enjoy popular culture. At the same time, corporations and governments encourage people to produce economic values through play.

Drawing from political economy, cultural studies and technology studies, this book will be essential reading for researchers and students of media technologies and popular culture in Northeast Asia.
