College football is the term given to the sport of football played between members of the National Collegiate Athletics Alliance (NCAA), which comprises of colleges all across the United States of America. Since 1908, the NCAA has hosted a "national championship" between the two teams that a board of pollsters deem the two most worthy in the country, and smaller "bowls" have held host to other excellent teams competing in athletic play. Over time, the "bowl system" has been developed to include impartial computers and several different polls put together mathematically to more fairly determine a winner, despite calls and suggestions for a playoff system similar to Major League Baseball, professional and collegiate ice hockey, and professional soccer.
