The book focuses on radio and sound docufiction and docudrama through comparative analysis of the British and the Italian output from post war years to the 2010s, from both a historical and formal point of view. It sheds light on a rather neglected area of study providing a systematic survey of the development of the form and of its current status and perspectives, and at the same time constructing viable analytical tools that can be used to investigate individual productions. Considering the different docudramatic output in formats and quantity in the two countries, the book explores case studies from BBC Radio, which continue to air a high number of programmes with a great variety of formats and subgenres, and Italian case studies from both independent bodies and the Radio RAI, whose docudramatic production has declined since the late 1980s. Specifically, the study seeks to explain how radio language in its purely acoustic dimension allows access to unpredictable layers of truth often complementary, when not overtly alternative, to the documental truth of declaredly journalistic or scientific programmes. A well-researched resource for university students, scholars, researchers and educators in media, sociology of media and history. In-depth analysis of an original topic.
