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 occasionally 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.
There are different kinds of art exhibitions, in particular there is a distinction between commercial and non-commercial exhibitions. A commercial exhibition or trade fair is often referred to as an art fair that shows the work of artists or art dealers where participants generally have to pay a fee. A vanity gallery is an exhibition space of works in a gallery that charges the artist for use of the space. Temporary museum exhibitions typically display items from the museum's own collection on a particular period, theme or topic, supplemented by loans from other collections, mostly those of other museums. They normally include no items for sale; they are distinguished from the museum's permanent displays, and most large museums set aside a space for temporary exhibitions.
Exhibitions in commercial galleries are often entirely made up of items that are for sale, but may be supplemented by other items that are not.
