An Exhibition, in the most general sense, is an organized presentation and display of a selection of items. In practice, exhibitions usually occur within a cultural or educational setting such as a Art Gallery or Exhibition Hall. Exhibitions can include many things such as art in both major Museums and smaller Galleries, Interpretive Exhibitions, and also varieties such as more commercially focused exhibitions and Trade Fairs.
Commercial exhibitions, generally called Trade Fairs, Trade Shows or Expos, are usually organized so that organizations in a specific interest or industry can showcase and demonstrate their latest products, service, study activities of rivals and examine recent trends and opportunities. Some trade fairs are open to the public, while others can only be attended by company representatives (members of the trade) and members of the press.
