Within media and cultural studies, the study of media texts is dominated by an exclusive focus on representation. This book adds long overdue attention to social interaction. The book is divided into two sections. The first outlines key theoretical issues and concepts, including informalisation, genre hybridisation, positioning, dialogism and discourse. The second is a sustained interrogation of social interaction in and around media. Re-examining issues of representation and interaction, it critically assesses work on the para-social and broadcast sociability, then explores distinct sites of interaction: production communities, audience communities and 'interactivity' with audiences.
