These categories generally operate simultaneously, however may be independent operations. A carnival may be set up at a shopping mall for the weekend or can run in conjunction with a fair having agricultural events, arts, crafts, exhibits, and more. An estimated 350 million people visit a carnival each year, making carnivals one of the most popular forms of family entertainment in the country. 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. 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.
