==Emergence of the Modern Game==
What ultimately became the National Football League originated in 1920 as the American Professional Football Association. Fourteen teams were the founding members but it soon expanded to twenty-two. The collegiate game, however, continued to influence how the game was played. In particular in the 1930s, passing rules were modified further that arguably made the game more like the modern one. The removal of a penalty or loss of five yards for a second incomplete pass and a loss of possession for an incomplete pass in the end zone now made passing a more important factor in American football. This helped to open up the game and subsequent rule changes helped to facilitate passing.
