The Proms or BBC Proms, formally named the Henry Wood Promenade Concerts Presented by the BBC, is an eight-week summer season of daily orchestral classical music concerts and other events held annually, predominantly in the Royal Albert Hall in central London. The Proms were founded in 1895, and are now organised and broadcast by the BBC. Each season consists of concerts in the Royal Albert Hall, chamber music concerts at Cadogan Hall, additional Proms in the Park events across the UK on the Last Night of the Proms, and associated educational and children's events. The season is a significant event in British culture and in classical music. Czech conductor Jiří Bělohlávek described the Proms as "the world's largest and most democratic musical festival".
Prom is short for promenade concert, a term which originally referred to outdoor concerts in London's pleasure gardens, where the audience was free to stroll around while the orchestra was playing. In the context of the BBC Proms, promming refers to the use of the standing areas inside the hall (the Arena and Gallery) for which ticket prices are much lower than for the seating. Proms concert-goers, particularly those who stand, are sometimes referred to as "Prommers" or "Promenaders".
