The Reith Lectures is a series of annual BBC radio lectures given by leading figures of the day. They are commissioned by the BBC and broadcast on Radio 4 and the World Service. The lectures were inaugurated in 1948 to mark the historic contribution made to public service broadcasting by Lord Reith, the corporation's first director-general.
Reith maintained that broadcasting should be a public service that aimed to enrich the intellectual and cultural life of the nation. It is in this spirit that the BBC each year invites a leading figure to deliver the lectures. The aim is to advance public understanding and debate about issues of contemporary interest.
