Primarily based on a transnational study of college students' net-radio consumption practices, this book uncovers two types of audiences (radio online or net-only radio audiences) and a three tiered net-radio subculture (conservatives, swingers and radicals), which is determined by users' taste distinctions and how much power they have over their net-radio consumption and production practices. The author contends that net-radio, its synergy with radio and music journalism and youth subcultures is not a trivial, flash in the pan, but an important (and ongoing) social-cultural and global phenomenon.
