Late-night talk show in the context of "House band"

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 the format is still widespread in some parts of the world, such as in the United Kingdom with the Royal Variety Performance, the Philippines with Eat Bulaga! and It's Showtime, 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.

Late-night television is one of the dayparts in television broadcast programming. It follows prime time and precedes the overnight television show graveyard slot. The slot generally runs from about 11:00 p.m. to 2:00 a.m., with variations according to the time zone and broadcaster.

In the United States and Canada, the term is synonymous with the late-night talk show, a type of television comedy talk show and variety show. Thus, the late-night programming block is considered more important in North America. On most major-network stations, a late-night news bulletin airs at the beginning of the block.

The mass media in Japan include numerous television and radio networks as well as newspapers and magazines in Japan. For the most part, television networks were established based on capital investments by existing radio networks. Variety shows, serial dramas, and news constitute a large percentage of Japanese evening shows.

Western movies are also shown, many with a subchannel for English. There are all-English television channels on cable and satellite (with Japanese subtitles).
