A trade show is an exhibition held on large grounds or exhibition halls where consumers and companies are brought together. Trade shows are the forum where companies can display their products and services. Consumers who visit these venues can interact with the company's salespeople, examine the products in real time and then decide whether to purchase them or not. It is the role of the event planning agencies to plan trade shows, booth themes, construction and design of trade show exhibits, booth rentals and such. These trade show exhibits are critical to attracting customers and an excellent exhibit can even lead to impulse buying on the part of the consumer.
