Sorry David T, you are only partially correct. The AFL (American Football Conference) did open for buisness win the late Chiefs owner Lamar Hunt decided to make his own leauge after the NFL turned him down for an expansion team in Dallas. Therefore, he created his own leauge and his own team in Dallas. The Dallas Texans, in 1964 he moved his team to the Kansas City and became the Chiefs. The first Super Bowl held in 1966 was between the Kansas City Chiefs and the Green Bay Packers. It was called the NFL - AFL championship game. The AFL was making a name for themselves and was drawing from the college talents in which the NFL used to have exclusive rights to for so many years prior. The AFL was doing quite well and was about to sign a rather large contract with NBC because of the popularity and quality of the teams such as the Kansas City Chiefs, The Oakland Raiders, The Houston Oilers, The Buffalo Bills, The Miami Dolphins The New York Jets, etc. There for the NFL commissioner Pete Rosell met with Lamar Hunt and representatives of the AFL because they saw this major threat of their rival league on not only talent, but dollars as well. Therefore they decided to merge after the 1969 season. In which the last two super bowls leading into that final merger were won by AFL teams (New York Jets, Kansas City Chiefs) showing proof that the quality of both leagues were equal. This merger thus created the two conferences we have today. The AFC (American Football Conference) and the NFC (National Football Conference).
