Changes

What ultimately became the National Football League originated in 1920 as the American Professional Football Association (APFA). 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. The 1930s saw more formal rules and procedures in the APFA. A championship game was added in 19331932. By 1941 there was a commissioner. AfterWorld War II, the NFL began to develop more teams. In 1958, the championship game was broadcast live on TV, which turned out to be a key moment for the NFL. By 1959, the newer American Football League had begun to compete with the NFL. This competition, however, eventually led to the NFL merging with the AFL, as it found success in bringing high profile players. The merged system eventually formed what today are the NFC and AFL within the NFL.
