The Festival of Nine Lessons and Carols was first held on Christmas Eve 1918. It was planned by Eric Milner-White, who at the age of thirty-four had just been appointed Dean of King's after experience as an army chaplain which had convinced him that the Church of England needed more imaginative worship. (He devised our Advent Carol Service in 1934, and was a liturgical pioneer and authority during his twenty two years as Dean of York.) The choir included sixteen trebles as laid down in King Henry VI's statutes, but until 1927 the men's voices were provided partly by Choral Scholars and partly by older Lay Clerks, and not, as now, by fourteen undergraduates. Almost immediately other churches adapted the service for their own use. A wider frame began to grow when the service was first broadcast in 1928 and, with the exception of 1930, it has been broadcast annually, even during the Second World War. Sometime in the early 1930s the BBC began broadcasting the service on overseas programmes. It is estimated that there are millions of listeners worldwide, including those to Radio Four in the United Kingdom. In recent years it has become the practice to broadcast a digital recording on Christmas Day on Radio Three, and since 1963 a shorter service has been filmed periodically for television.
