A nightclub (also known as a discothèque, disco, dance club or club) is an entertainment venue which usually operates late into the night. A nightclub is generally distinguished from bars, pubs or taverns by the inclusion of a dance floor and a DJ booth, where a DJ plays recorded music. The busiest nights for a nightclub are Friday and Saturday night.
The music in nightclubs is either live bands or, more commonly, a mix of songs played by a DJ through a powerful PA system. Most clubs or club nights cater to certain music genres.
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 US Prohibition, 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).
