We are particularly interested in finding out what archival material survives that sheds light on how radio crossed borders: what material about the BBC World Service, for example, survives in archives outside Britain, and where has programme material been preserved? We plan to investigate what audiences made of international broadcasting, in Europe, the Americas, Africa and Asia.

We want to hear from people who are interested in the history of international broadcasting, and we want to think about issues like radio monitoring, programme making and audience responses, radio technologies and infrastructure, and the auditory cultures and soundscapes of the past – what international radio actually sounded like, and how people listened to and heard it.
