There are approximately 500 carnivals that travel the United States each year, ranging in size from one or two rides to over 100 portable rides. Most carnivals remain family owned businesses with second and even third generation ownership. Almost all carnivals are sponsored by non-profit organizations which receive a significant portion of the proceeds from the event. Carnivals have helped to fund scholarships, buy needed fire or emergency rescue equipment, and generally help organizations fund charity work in almost every community in the country. The carnival made its debut in North America in 1894 when Frank C. Bostock brought their model of an English Fair to the United States.
Carnivals remain one of the safest forms of family entertainment.
Some carnivals carry a portable school and full time teacher so the children of workers can receive a top quality education while their parents travel the country. The various stops along the carnival's route make for excellent field trips. The OABA now has almost 500 member carnivals and over 5,000 total members. For over 35 years the OABA has been at the forefront in establishing safety guidelines and regulations, lobbying governments on behalf of small business, establishing a code of ethics for the industry and promoting the interests and image of the carnival industry throughout North America.
