Technology ArticleFootball a great American pastime American football, known in the United States and Canada simply as football, is a competitive team sport known for mixing strategy with physical play. The objective of the game is to score points by advancing the ball into the opposing team's end zone. The ball can be advanced by carrying it (a running play) or by throwing it to a teammate (a passing play). Points can be scored in a variety of ways, including carrying the ball over the opponent's goal line; catching a pass from beyond that goal line; kicking the ball through the goal posts at the opponent's end zone; and tackling an opposing ballcarrier within his end zone. The winner is the team with the most points when the time expires. The sport is also played outside the United States. National leagues exist in Germany, Italy, Switzerland, Finland, Sweden, Japan, Mexico, Israel, Spain, Austria and several Pacific Island nations. The National Football League, the largest professional American football league in the world, ran a developmental league in Europe from 1991–1992 and then from 1995–2006. American football is closely related to Canadian football, but with significant differences. Both sports originated from rugby football. A standard football game consists of four 15-minute quarters (12-minute quarters in high-school football and often shorter at lower levels), with a half-time intermission after the second quarter. The clock stops after certain plays; therefore, a game can last considerably longer (often more than three hours in real time), and if a game is broadcast on television, TV timeouts are taken at certain intervals of the game to broadcast commercials outside of game action. If an NFL game is tied after four quarters, the teams play an additional period lasting up to 15 minutes. In an NFL overtime game, the first team that scores wins, even if the other team does not get a possession; this is referred to as sudden death. In a regular-season NFL game, if neither team scores in overtime, the game is a tie. In an NFL playoff game, additional overtime periods are played, as needed, to determine a winner. College overtime rules are more complicated and are described in Overtime (sport).
