Variety show, also known as variety arts or variety entertainment, is entertainment made up of a variety of acts including musical performances, sketch comedy, magic, acrobatics, juggling, and ventriloquism. It is normally introduced by a compère (master of ceremonies) or host. The variety format made its way from the Victorian era stage in Britain and America to radio and then television. Variety shows were a staple of English language television from the late 1940s into the 1980s.
While still widespread in some parts of the world, such as in the United Kingdom with the Royal Variety Performance, and South Korea with Running Man, the proliferation of multichannel television and evolving viewer tastes have affected the popularity of variety shows in the United States. Despite this, their influence has still had a major effect on late night television whose late-night talk shows and NBC's variety series Saturday Night Live (which originally premiered in 1975) have remained popular fixtures of American television.
The live entertainment style known as music hall in the United Kingdom and vaudeville in the United States can be considered a direct predecessor of the "variety show" format. Variety in the UK evolved in theatres and music halls, and later in Working Men's Clubs. British performers who honed their skills in music hall sketches include Charlie Chaplin, Stan Laurel, George Formby, Gracie Fields, Dan Leno, Gertrude Lawrence, and Marie Lloyd. Most of the early top performers on British television and radio did an apprenticeship either in stage variety, or during World War II in Entertainments National Service Association (ENSA). In the UK, the ultimate accolade for a variety artist for decades was to be asked to do the annual Royal Command Performance at the London Palladium theatre, in front of the monarch. Later known as the Royal Variety Performance (from 1919), it continues today. In the 1940s, Stan Laurel revisited his music hall days when he performed at the Royal Variety show.
