As the largest city in the U.S., New York was a breeding ground for failed pro sports franchises during the early part of the 20th century. The city was home to eight NFL franchises that had all folded by 1951, while the Jets and Giants endured. More recently, the Giants and Dodgers of the MLB decamped for California after the 1957 season. New York has also passed the Nets franchise back and forth with New Jersey. The team currently plays in Brooklyn.
