During the course of several decades, several scientists and groups of scientists lobbied the British Broadcasting Corporation (BBC) about science broadcasting. A consistent theme of the interventions was that science broadcasting should be given exceptional treatment both in its content, which was to have a strongly didactic element, and in its managerial arrangements within the BBC. This privileging of science would have amounted to ‘scientific exceptionalism’. The article looks at the nature of this exceptionalism and broadcasters' responses to it.
