Even after the emergence of the professional National Football League (NFL), college football remained extremely popular throughout the U.S. Although the college game has a much larger margin for talent than its pro counterpart, the sheer number of fans following major colleges provides a financial equalizer for the game, with Division I programs the highest level playing in huge stadiums, six of which have seating capacity exceeding 100,000. In many cases, college stadiums employ bench-style seating, as opposed to individual seats with backs and arm rests. This allows them to seat more fans in a given amount of space than the typical professional stadium, which tends to have more features and comforts for fans. (Only two stadiums owned by U.S. colleges or universities Papa John's Cardinal Stadium at the University of Louisville and FAU Stadium at Florida Atlantic University consist entirely of chairback seating.) - The National Collegiate Athletic Association (NCAA) is a non-profit association which regulates athletes of 1,281 institutions, conferences, organizations, and individuals. It also organizes the athletic programs of many colleges and universities in the United States and Canada, and helps more than 450,000 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 Men's Division I Basketball Tournament. This revenue is then distributed back into various organizations and institutions across the United States. - Joe Aillet Stadium (formerly Louisiana Tech Stadium) is a college football stadium in Ruston, Louisiana and the home field of the Louisiana Tech University Bulldogs football team, which competes in Conference USA.
