By the early 1960s, speed equipment had grown from a cottage industry into a substantial business. Manufacturers faced shared questions: how to establish quality and safety standards, how to work with regulators, and how to present the industry to retailers and the public.

In 1963, a group of manufacturers founded the Speed Equipment Manufacturers Association — SEMA. Among its early priorities was developing standards for performance products.

From speed equipment to specialty equipment

As the industry broadened beyond racing parts to include accessories, wheels, styling products, and more, the organization changed its name to the Specialty Equipment Market Association while keeping the SEMA acronym.

The association's annual trade show, held in Las Vegas, has grown into one of the largest automotive trade events in the world.
