The New York Giants, an American football team which currently plays in the National Football League's National Football Conference, has a history dating back more than 80 seasons. The Giants were founded in 1925 by Tim Mara in the then five-year-old NFL. Mara owned the team until his death in 1959, when it was passed on to his sons, Wellington and Jack. During their history, the Giants have won eight NFL championships, four of which came in Super Bowls.
In just its third season, the team finished with the best record in the league at 11–1–1 and was awarded the NFL title. In a 14-year span beginning in 1933, New York qualified to play in the NFL championship game eight times, winning twice (1934 and 1938). They did not win another championship until 1956, aided by several future Hall of Fame players such as running back Frank Gifford, linebacker Sam Huff, and offensive tackle Roosevelt Brown. From 1958 to 1963, the Giants played in the NFL championship game five times, but failed to win. The 1958 NFL Championship game, in which they lost 23–17 in overtime to the Baltimore Colts, is credited with increasing the popularity of the NFL in the United States.
The Giants registered just two winning seasons from 1964 to 1980 and were unable to advance to the playoffs. From 1981 to 1990, the team qualified for the postseason seven times and won Super Bowls XXI and XXV. The team's success during the 1980s was aided by head coach Bill Parcells, quarterback Phil Simms and Hall of Fame linebackers Lawrence Taylor and Harry Carson. New York struggled throughout much of the 1990s as Parcells left the team, and players such as Simms and Taylor declined and eventually retired. They returned to the Super Bowl in 2000, but lost to the Baltimore Ravens in Super Bowl XXXV. The Giants upset the heavily favored New England Patriots in Super Bowls XLII and XLVI.
