Prior to the advent of the Super Bowl for the 1966 season, the AFL went to great lengths to avoid scheduling its playoffs head-to-head with the NFL. In 1960, the NFL's game was held on Monday, December 26; the AFL had that week off, and played its title contest on Sunday, January 1, as the college bowl games were played on Monday. In 1961 and 1962, the AFL played its game during the off-week between the end of the NFL's regular season and its title game (thus resulting in the AFL holding championship games on December 24, 1961, and December 23, 1962, a week before the NFL's games of December 31, 1961, and December 30, 1962). In 1963, the AFL held its Eastern Division tiebreaker playoff on Saturday, December 28, 1963, thereby avoiding the NFL championship game that Sunday (the AFL championship game was held on January 5). In 1964, pro football had a championship weekend, with the AFL's title game held on Saturday, December 26, and the NFL championship on Sunday. For 1965, the AFL tried to return to the practice of playing its game on a Sunday during the off-week between the NFL playoff, slating its championship contest for December 26, while the NFL's game was not held until January 2, 1966; unfortunately, the Colts and Packers required a Western Conference tiebreaker on the December 26, date --- and since that game went to overtime, the TV audience for the Bills–Chargers title game in San Diego was diminished considerably. Even in 1966, the AFL originally scheduled its championship game for the off-week, planning to hold its playoff on Monday, December 26, six days before the NFL title game on January 1.
