Our lives are more mediated than ever before. Adults in economically advanced countries spend, on average, over eight hours per day interacting with the media. The news and entertainment industries are being transformed by the shift to digital platforms. But how much is really changing in terms of what shapes media content? What are the impacts on our public and imaginative life? And is the Internet a democratising tool of social protest, or of state and commercial manipulation?Drawing on decades of research to examine these and other questions, Understanding Media interrogates claims about the Internet, explores how representations in TV and film may influence perceptions of self, and traces overarching trends while attending to crucial local context, from the United States to China, Norway to Malaysia, and Brazil to Britain. Understanding Media is an accessible and essential guide to the world's most influential force - the contemporary media.
