When you hear an old school announcer say the phrase, "The New York Football Giants," it may seem a bit redundant. But there's a reason for the longer name. In 1937, the Giants changed their name to the "New York Football Giants" to distinguish themselves from the New York Giants baseball team, which played its home games at Manhattan's Polo Grounds for nearly 70 years. Even though the Giants moved to San Francisco after the 1957 season, "New York Football Giants, Inc." is still the legal name of the team," a friendly reminder in case you're watching the Giants in a particularly bad game and couldn't tell the sport for sure.
