The National Collegiate Athletic Association (NCAA) is a non-profit organization which regulates athletes of 1,281 institutions, conferences, and individuals. It also organizes the athletic programs of many colleges and universities in the United States and Canada, and helps more than 480,000 college student-athletes who compete annually in college sports. The organization is headquartered in Indianapolis, Indiana. In 2014, the NCAA generated almost a billion dollars in revenue. 80 to 90% of this revenue was due to the Division I Men's Basketball Tournament. This revenue is then distributed back into various organizations and institutions across the United States.
