I. Description of Fairs, Expositions and Exhibitions
B. Types of Exhibitions

Trade Shows
or b2b shows do have certain distinguishing characteristics that set them apart from consumer or combined shows. The exhibitor is typically a manufacturer or distributor of products or services specific or complementary to those industries authorized to the show. The typical buyer is an industrial end user, or another distributor, within the industry segment hosting the exposition. Attendance is restricted to these buyers and is often by invitation only. Business credentials or pre-registration are usually required to qualify the buyer as a legitimate member of the trade or industry. An access or registration fee may also have to be paid prior to admission to the event. Trade show events may be as short as a single day or as long as seven to 10 days depending on the markets being served. Some are held semi-annually. Most are held annually, a few biennially. Some large-scale industrial expositions are held once every three to seven years.11)
