Starting as What Do You Know? in 1953, and changing its title in 1967, BBC Radio 4's Brain of Britain is probably ‘the most venerable of general knowledge quizzes anywhere’. With this book you can challenge your own brain with 2,000 questions (50 quizzes of 40 questions each) drawn from the programme’s archives. By way of introduction, the current presenter, Russell Davies, has written a history of Brain of Britain and shares his thoughts on ‘this quiz lark’.
