An exhibition, in the most general sense, is an organized presentation and display of a selection of items. 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. It’s a media where buyer, seller and product physically come together – a potent force for business. 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.
