Radiophilia, the new book in The Study of Sound Series, discusses radio in the context of recent literature about affects and emotions. Informed by various traditions within media and cultural studies, and guided by the work of Lauren Berlant and Arjun Appudarai, it approaches ‘radiophilia’ -love for, or strong attachment to, radio—as a wide-reaching concept that includes groups practices and social moods and that can be practised in public spaces and communities, beyond interior and domestic set-ups.
