Although both of New York City's football teams play today across the Hudson River in MetLife Stadium in East Rutherford, New Jersey, both teams started out playing in the Polo Grounds. The New York Giants played side-by-side with their baseball namesakes from the time they entered the National Football League in 1925, until crossing over to Yankee Stadium in 1956. The New York Jets, originally known as the "Titans of New York", started out in 1960 at the Polo Grounds, staying there for four seasons before joining the Mets in Queens at Shea Stadium in 1964.
