The season ended when the New York Jets defeated the Oakland Raiders in the AFL Championship Game; the Jets then defeated the National Football League's Baltimore Colts in Super Bowl III in one of the biggest sports upsets in history.
This season was also notable for arguably the most memorable regular season game in pro football history: the Heidi Game. A commitment to a sponsor caused NBC to switch coverage from a late season matchup between the Jets and Raiders to a children's movie, infuriating millions of viewers.
With the addition of the Cincinnati Bengals, the AFL's ten teams were grouped into two divisions. Each team would play a home-and-away game against the other four teams in its division, one game against each of the five teams in the opposite division, and a second game against one of the other division's teams.
The best team in the Eastern Division would play against the best in the Western Division in a championship game. If there was tie in the standings (as happened when Oakland and Kansas City both finished at 12-2-0), a playoff would be held to determine the division winner.
