In 1938 Britain started to quiz. Since then, quizzes have become ubiquitous entertainment from pubs to primetime, suffered major criminal investigations, created unlikely folk heroes and been subjected to the rigours of question checkers. 'The Joy of Quiz' tells the history of quiz and its makers, wonders how we came to make a game out of remembering scraps of information, looks at the tactics of professional quizzers and reveals the shadowy worlds of setters and checkers. Along the way, it asks questions such as 'What is a fact, anyway?' and 'Whatever happened to prizes like sandwich toasters?'
