Defining The Major American Trade Show

Major American Trade Shows are comprised of not-for-profit and for-profit exhibitions with at least 200,000 NSF of exhibition space.

Major American Trade Show Organizers (MATSO) History

The founding of MATSO began in the late 1970s and formalized as a corporation in 1985 when it was originally chartered in Chicago as a means of coordinating dialogue among the city’s major trade show producers. Over the years, the exchanges focused on operational challenges particularly relevant to events of scale and complexity. There was a larger vision to broaden its geographic reach beyond Chicago and expand the internal focus from solely operations to include all functional aspects of major show production, including marketing and sales, legislation, labor, international challenges and operation. The founders wanted to create a collective voice reflecting the unique perspective of the producers of major, industry-leading events. MATSO’s initial fundamentals included:

  • Wide-open exchange of ideas and solutions in a competition-free environment
  • A forum to support in-depth problem-solving as a group , addressing major-scale challenges that threaten the stability of the industry
  • Ongoing dialogue to support establishing meaningful Best Practices for major events
  • The collective voice to influence the industry marketplace for the betterment of major event producers
  • Perpetuating a non-commercial environment
