For example, in the U.S., there are currently over 10,000[1] trade shows held every year, and several online directories have been established to help organizers, attendees, and marketers identify appropriate events.
These markets were held annually or on several specific days a year, usually at geographically particularly favorable locations and in conjunction with a religious festival in order to benefit from the rush of the public.
In the late 19th century, the concept of annual industry-wide trade shows gained traction, spreading from European manufacturing centers to North America.
[3] Generally there will be a central trade show floor with booths where people exhibit their goods or services, and throughout the day there will be seminars for continuing education on matters relevant to the industry, like best practices, trends, and regulation.
[6] Costs include space rental, booth design and construction of trade show displays, telecommunications, travel, accommodations, and promotional literature and items to give to attendees.
