The Giants were one of five teams that joined the NFL in 1925, and is the only one of that group still existing, as well as the league's longest-established team in the Northeastern United States. The team ranks third among all NFL franchises with eight NFL titles: four in the pre–Super Bowl era (1927, 1934, 1938, 1956) and four since the advent of the Super Bowl (Super Bowls XXI (1986), XXV (1990), XLII (2007), and XLVI (2011)), along with more championship appearances than any other team, with 19 overall appearances. Their championship tally is surpassed only by the Green Bay Packers (13) and Chicago Bears (9). During their history, the Giants have featured 28 Hall of Fame players, including NFL Most Valuable Player (MVP) award winners Mel Hein, Frank Gifford, Y. A. Tittle, and Lawrence Taylor.
To distinguish themselves from the professional baseball team of the same name, the football team was incorporated as the "New York National League Football Company, Inc." in 1929 and changed to "New York Football Giants, Inc." in 1937. Although the baseball team moved to San Francisco after the 1957 season, the football team continues to use "New York Football Giants, Inc." as its legal corporate name, and is often referred to by fans and sportscasters as the "New York Football Giants". The team has also gained several nicknames, including "Big Blue", the "G-Men", and the "Jints", an intentionally mangled contraction seen frequently in the New York Post and New York Daily News, originating from the baseball team when they were based in New York. Additionally, the team as a whole is occasionally referred to as the "Big Blue Wrecking Crew", even though this moniker primarily and originally refers to the Giants defensive unit during the 80s and early 90s (and before that to the Los Angeles Dodgers baseball teams of the late 1970s and early 1980s).
The team's heated rivalry with the Philadelphia Eagles is the oldest of the NFC East rivalries, dating all the way back to 1933, and has been called the best rivalry in the NFL in the 21st century.
