Harvard's athletic rivalry with Yale is intense in every sport in which they meet, coming to a climax each fall in the annual football meeting, which dates back to 1875 and is usually called simply "The Game." While Harvard's football team is no longer one of the best as it was in football's early days, both Harvard and Yale have influenced the way the game is played. In 1903, Harvard Stadium introduced a new era into football with the first permanent reinforced concrete stadium of its kind in the country.
