Radio Times is Britain's oldest and probably best known TV listings magazine and one of the largest circulation magazines in the country - it sells 1.3 million copies and is read by 3.8 million people each week, biased towards an up-market readership and with a fairly even spread across age-bands. It is published by BBC Worldwide, the commercial arm of the BBC. Apart from full TV and radio listings it contains film reviews, features and celebrity interviews.
