This text considers how far culture can be regulated through formal controls on the media and how such controls are shaped and contested in an age of cultural diversity and global cultural industries. The book deals with such aspects of regulation as: sexuality, which poses issues of the control of representations, pornography and censorship; globalization, which raises questions of national identity and cultural imperialism; and multiculturalism, which challenges existing models of cultural identity and citizenship. These three arenas pose very different issues for the formation and regulation of the media, clarifying the debates about public definitions of culture, identity and difference.
