A nightclub ( or club) is an entertainment venue and bar which serves alcoholic beverages that usually operates late into the night. A nightclub is generally distinguished from regular bars, pubs or taverns by the inclusion of a stage for live music, one or more dance floor areas and a DJ booth, where a DJ plays recorded music and where coloured lights illuminate the dance area. Another distinction is that whereas many pubs and sports bars aim at a mass market, nightclubs typically aim at a niche market of music and dancing enthusiasts and clubgoers. The upmarket nature of nightclubs can be seen in the inclusion of VIP areas in some nightclubs, for celebrities and their guests. Nightclubs are much more likely than pubs or sports bars to use bouncers to screen prospective clubgoers for entry. Some nightclub bouncers do not admit people with ripped jeans or other informal clothing or gang apparel as part of a dress code. The busiest nights for a nightclub are Friday and Saturday night. Most clubs or club nights cater to certain music genres, such as house music or gothic rock.
A nightclub may also be called a discothèque or disco (these terms were generally used for 1970s and early 1980s-era venues), dance club, dance bar or live music club.
From about 1900 to 1920, working class Americans would gather at honky tonks or juke joints to dance to music played on a piano or a jukebox. Webster Hall is credited as the first modern nightclub, being built in 1886 and starting off as a "social hall", originally functioning as a home for dance and political activism events. During Prohibition in the United States, nightclubs went underground as illegal speakeasy bars, with Webster Hall staying open, with rumors circulating of Al Capone's involvement and police bribery. With the repeal of Prohibition in February 1933, nightclubs were revived, such as New York's 21 Club, Copacabana, El Morocco, and the Stork Club. These nightclubs featured big bands (there were no DJs).
