Super Bowl
–
The Super Bowl is the annual championship game of the National Football League. The game is the culmination to a season that begins in the late summer of the previous calendar year. Normally, Roman numerals are used to each game, rather than the year in which it is held. For example, Super Bowl I was played on January 15,1967, the single exception to this rule is Super Bowl 50, which was played on February 7,2016, following the 2015 regular season. The next game, Super Bowl LII, scheduled for February 4,2018, the game was created as part of a merger agreement between the NFL and its then-rival league, the American Football League. It was agreed that the two champion teams would play in the AFL–NFL World Championship Game until the merger was to officially begin in 1970. After the merger, each league was redesignated as a conference, currently, the National Football Conference leads the league with 26 wins to 25 wins for the American Football Conference. The Pittsburgh Steelers have the most Super Bowl championship titles, with six, the New England Patriots have the most Super Bowl appearances, with nine. The day on which the Super Bowl is played, now considered by some as an unofficial American national holiday, is called Super Bowl Sunday and it is the second-largest day for U. S. food consumption, after Thanksgiving Day.

However, in 1960, it encountered its most serious competitor when the American Football League was formed. The AFL vied heavily with the NFL for both players and fans, but by the middle of the decade the strain of competition led to merger talks between the two leagues. Prior to the 1966 season, the NFL and AFL reached an agreement that was to take effect for the 1970 season. As part of the merger, the champions of the two agreed to meet in a world championship game for professional American football until the merger was effected. A bowl game is a college football game. Exploiting the Rose Bowl Games popularity, post-season college football contests were created for Miami, New Orleans, and El Paso, Texas in 1935, by the time the first Super Bowl was played, the term bowl for any major American football game was well established

Tackle (football move)
–
Most forms of football have a move known as a tackle. The primary and important purposes of tackling are to dispossess an opponent of the ball, the word is used in some contact variations of football to describe the act of physically holding or wrestling a player to the ground. In others, it simply one or more methods of contesting for possession of the ball. It can therefore be used as both a defensive or attacking move, in Middle Dutch, the verb tacken meant to grab or to handle. By the 18th century, a use was applied to harnesses or equipment used with horses. Modern use in football comes from the sport of rugby. In any such case, the ball becomes dead, the down is over, a tackle is known as a quarterback sack when the quarterback is tackled behind the line of scrimmage while attempting to throw a pass. A tackle for loss indicates a tackle that causes a loss of yardage for the running back or wide receiver. When a player who does not have the ball is taken down it is referred to as a block. Tackles can also be made by grabbing the ball carriers jersey, as mentioned above, the referee can declare that a play is dead if the ball carriers forward progress has been stopped, even if he has not actually been taken to the ground. To protect players from potentially catastrophic injury, there are restrictions on tackles. At no time may a defensive player tackle a player by grabbing the facemask of their helmet, doing so incurs a 15-yard penalty. A similar penalty is assessed to any player attempting to contact with his helmet against another opponents helmet. Grabbing a ball carrier by the pads behind his neck and pulling him down is known as a horse collar, a method which has been made illegal at all levels of American football. However, in the NFL a player can continue forward for one step, place kickers and punters are afforded an even greater protection from being tackled. Once the play is ruled complete, no contact is permitted, a player who makes contact with an opponent after the play is charged with unnecessary roughness and his team is assessed a 15-yard penalty. However, a player who plays on the line can block below the knees as long the block is five yards of the line. In the National Football League, tackles are tracked as a statistic by a scorekeeper hired by the home team

American football
–
The offense must advance at least ten yards in four downs, or plays, or else they turn over the football to the opposing team, if they succeed, they are given a new set of four downs. Points are primarily scored by advancing the ball into the teams end zone for a touchdown or kicking the ball through the opponents goalposts for a field goal. The team with the most points at the end of a game wins, American football evolved in the United States, originating from the sports of association football and rugby football. The first game of American football was played on November 6,1869, during the latter half of the 1870s, colleges playing association football switched to the Rugby Union code, which allowed carrying the ball. American football as a whole is the most popular sport in the United States, Professional football and college football are the most popular forms of the game, with the other major levels being high school and youth football. As of 2012, nearly 1.1 million high school athletes and 70,000 college athletes play the sport in the United States annually, almost all of them men, in the United States, American football is referred to as football. The term football was established in the rulebook for the 1876 college football season. The terms gridiron or American football are favored in English-speaking countries where other codes of football are popular, such as the United Kingdom, Ireland, New Zealand, American football evolved from the sports of association football and rugby football. What is considered to be the first American football game was played on November 6,1869 between Rutgers and Princeton, two college teams, the game was played between two teams of 25 players each and used a round ball that could not be picked up or carried. It could, however, be kicked or batted with the feet, hands, head or sides, Rutgers won the game 6 goals to 4. Collegiate play continued for years in which matches were played using the rules of the host school. Representatives of Yale, Columbia, Princeton and Rutgers met on October 19,1873 to create a set of rules for all schools to adhere to. Teams were set at 20 players each, and fields of 400 by 250 feet were specified, Harvard abstained from the conference, as they favored a rugby-style game that allowed running with the ball. An 1875 Harvard-Yale game played under rugby-style rules was observed by two impressed Princeton athletes and these players introduced the sport to Princeton, a feat the Professional Football Researchers Association compared to selling refrigerators to Eskimos. Princeton, Harvard, Yale and Columbia then agreed to play using a form of rugby union rules with a modified scoring system. These schools formed the Intercollegiate Football Association, although Yale did not join until 1879, the introduction of the snap resulted in unexpected consequences. Prior to the snap, the strategy had been to punt if a scrum resulted in bad field position, however, a group of Princeton players realized that, as the snap was uncontested, they now could hold the ball indefinitely to prevent their opponent from scoring. In 1881, both teams in a game between Yale-Princeton used this strategy to maintain their undefeated records, each team held the ball, gaining no ground, for an entire half, resulting in a 0-0 tie
