The New York Giants were founded in 1925. Of the five teams that entered the league that year, they are the only one still around. They derived their name from the baseball team of the same name, which has since moved from New York to San Francisco. They represent the New York metropolitan area, which includes parts of New York, New Jersey, and Connecticut. Their home stadium, MetLife Stadium, is located in East Rutherford, NJ. They share this stadium with the New York Jets. The Giants and the Jets are the two teams in the NFL to share a stadium and hometown.
The Giants have won 8 league championships, the third of all time for NFL franchises. Of them are 4 pre-Super Bowl championships in 1927, 1934, 1938, and 1956, and 4 Super Bowls in 1986, 1990, 2007, and 2011. They have made 19 championship appearances, the most of all NFL franchise. They are the only team to have won a Super Bowl in four consecutive decades. The Giants have also won 16 division titles (8 in the NFL East, 8 in the NFC East).
The Giants' biggest rivalry is the Philadelphia Eagles. The Eagles and the Giants have been rivals since the Eagles' founding in 1933, almost 40 years before the New York Giants joined the Eagles' division in the NFC East. Fueled by proximity (Philadelphia is located 97 miles from New York), passionate fanbases, and similar rivalries in other sports (Mets-Phillies in the MLB and Rangers-Flyers in the NHL), the rivalry is one of the most intense in the entire league. NFL Network ranked it the #1 NFL rivalry of all time.
The Giants also have a heated relationship with the Dallas Cowboys. It is the only Texas-New York rivalry in American sports. After a dominant period for the Cowboys in the 1970's, the rivalry has been very competitive with neither team taking a significant win streak.
The Giants have 29 former players in the Hall of Fame, the second most for any NFL franchise. Five Giants have won the NFL MVP award while playing for the team, the most recent being linebacker Lawrence Taylor in 1986. LT is also the most recent defensive player to win the NFL MVP.
