Unlike most other sports in North America, no official minor league farm organizations exist in American or Canadian football. Therefore, college football is generally considered to be the second tier of American football in the United States and Canadian football in Canada; one step ahead of high school competition, and one step below professional competition. However, in some areas of the country, college football is more popular than professional football, and for much of the early 20th century, college football was seen as more prestigious than professional football.
