List of New England Patriots seasons
The modern NFL championship game, the Super Bowl, was founded in the 1966 season; the first four were contested between the champions of the AFL and the NFL. After the merger, the Super Bowl became the united league's championship. The Patriots made the 1963 AFL Championship Game, but struggled severely in the early years of the united league, not making the postseason until 1976. After a few good seasons including a Super Bowl appearance against a champion Bears outfit, the Patriots reached a nadir between 1989 and 1993 when they won only 19 of 80 games.
