“The Proms, which run to 57 consecutive nights, are regularly billed as the world’s biggest music festival. Last year’s average attendance was 93 per cent of the Albert Hall’s 6,000-seat capacity – and that’s just a fraction of the total number listening. In the UK alone, live transmissions on BBC Radio 3 are heard by 2m people a week, and in 2012 more than 15m watched on television. BBC broadcasts reach a huge international audience, with more than 45 countries transmitting the Proms on radio and up to 20 tuning into the Last Night on television.”
