An art exhibition is traditionally the space in which art objects (in the most general sense) meet an audience. The exhibit is universally understood to be for some temporary period unless, as is rarely true, it is stated to be a "permanent exhibition". In American English, they may be called "exhibit", "exposition" (the French word) or "show". In UK English, they are always called "exhibitions" or "shows", and an individual item in the show is an "exhibit". Such expositions may present pictures, drawings, video, sound, installation, performance, interactive art, new media art or sculptures by individual artists, groups of artists or collections of a specific form of art. The art works may be presented in museums, art halls, art clubs or private art galleries, or at some place the principal business of which is not the display or sale of art, such as a coffeehouse. An important distinction is noted between those exhibits where some or all of the works are for sale, normally in private art galleries, and those where they are not. Sometimes the event is organized on a specific occasion, like a birthday, anniversary or commemoration.
