Sports in the United States
Sports in the United States are an important part of the country's culture. Based on revenue, the four major professional sports leagues in the United States are Major League Baseball (MLB), the National Basketball Association (NBA), the National Football League (NFL), and the National Hockey League (NHL). The market for professional sports in the United States is roughly $69 billion, roughly 50% larger than that of all of Europe, the Middle East, and Africa combined. Major League Soccer is sometimes included in a "top five" of leagues of the country. All four enjoy wide-ranging domestic media coverage and are considered the preeminent leagues in their respective sports in the world, although only basketball, baseball, and ice hockey have substantial followings in other nations.
Playoffs
The playoffs, play-offs, postseason and/or finals of a sports league are a competition played after the regular season by the top competitors to determine the league champion or a similar accolade. Depending on the league, the playoffs may be either a single game, a series of games, or a tournament, and may use a single-elimination system or one of several other different playoff formats. Playoff, in regard to international fixtures, is to qualify or progress to the next round of a competition or tournament. In team sports in the U.S. and Canada, the vast distances and consequent burdens on cross-country travel have led to regional divisions of teams.
Sport in the United Kingdom
The United  Kingdom has given birth to a range of major international sports including: association football, rugby (union and league), cricket, netball, darts, golf, tennis, table tennis, badminton, squash, bowls, modern rowing, hockey, boxing, snooker, billiards, and curling. This has meant that in the infancy of many sports, England, Scotland, Wales and Ireland formed among the earliest separate governing bodies, national teams and domestic league competitions. After 1922 some sports formed separate bodies for Northern Ireland though some continued to be organised on an all-Ireland basis. In a small number of sports, these teams are supplemented by high-profile events featuring a combined team representing one or more nations.
History of American football
The history of American football can be traced to early versions of rugby football and association football. Both games have their origin in varieties of football played in Britain in the mid-19th century, in which a football is kicked at a goal or kicked over a line, which in turn were based on the varieties of English public school football games. American football resulted from several major divergences from association football and rugby football, most notably the rule changes instituted by Walter Camp, a Yale University and Hopkins School graduate who is considered to be the "Father of American Football".

The early history of American football can be traced to early versions of rugby football and association football. Both games have their origin in varieties of football played in Britain in the mid–19th century, in which a football is kicked at a goal or run over a line, which in turn were based on the varieties of English public school football games. American football resulted from several major divergences from association football and rugby football, most notably the rule changes instituted by Walter Camp, a Yale University and Hopkins School graduate considered to be the "father of gridiron football".
Soccer in the United States
Soccer in the United States is governed by the United States Soccer Federation. The organization governs most levels of soccer in the country, including the national teams, professional leagues, and the amateur game with the exception of colleges and high schools. , over 24.4 million people play soccer in the United States. In 2012, the U.S. Census Bureau reported that soccer was the third-most played team sport in the U.S., behind only basketball and baseball. The popularity of the sport in the U.S. has been growing since the 1960s and 1970s, and received a significant boost when the United States hosted the 1994 FIFA World Cup and 1999 FIFA Women's World Cup.
Sports in Canada
Sports in Canada consist of a wide variety of games. The most common sports are ice hockey, lacrosse, football, soccer, basketball, curling and baseball, with ice hockey and lacrosse being the official winter and summer sports, respectively. Ice hockey, referred to as simply "hockey", is Canada's most prevalent winter sport, its most popular spectator sport, and its most successful sport in international competition. It is Canada's official national winter sport. Lacrosse, a sport with Indigenous origins, is Canada's oldest and official summer sport. Canadian football is Canada's second most popular spectator sport, being the most popular in the prairie provinces.

American football
American football, referred to as football in the United States and Canada, and also known as gridiron football or simply gridiron, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, which is the team controlling the oval-shaped football, attempts to advance down the field by running with or passing the ball, while the defense, which is the team without control of the ball, aims to stop the offense's advance and aims to take control of the ball for themselves. The offense must advance at least ten yards in four downs, or plays, and otherwise they turn over the football to the defense; if the offense succeeds in advancing ten yards or more, they are given a new set of four downs.
Association football
Association football, more commonly known as football or soccer, is a team sport played between two teams of eleven players with a spherical ball. It is played by 250 million players in over 200 countries and dependencies, making it the world's most popular sport. The game is played on a rectangular field with a goal at each end. The object of the game is to score by getting the ball into the opposing goal. Players are not allowed to touch the ball with their hands or arms while it is in play, unless they are goalkeepers (and then only when within their penalty area). Other players mainly use their feet to strike or pass the ball, but may also use any part of their body except the hands and the arms.
Comparison of American and Canadian football
American and Canadian football are gridiron codes of football that are very similar. Both have their origins in rugby football. There are, however, some key differences. Football was introduced to North America in Canada by the British Army garrison in Montreal, which played a series of games with McGill University. In 1874, the U.S. Harvard University hosted Canada's McGill University to play the new game derived from rugby football in a home-and-home series. When the Canadians arrived several days early, to take advantage of the trip to see Boston and the surrounding areas, they held daily practices.
Comparison of American football and rugby union
A comparison of American football and rugby union is possible because of the games' shared origins, despite their dissimilarities. In the event of a tackle in rugby the player may pass the ball behind him provided he is not on the ground. If the tackled player is on the ground, the ball must be released, allowing any other player (including the opposition) to pick up the ball (usually a ruck forms) and the play continues. In the event of a tackle in American Football the play is concluded and the team on offense maintains possession usually if either the ball was advanced past the first down marker (resulting in a first down and a renewal of the down count) or else the down count advances (although if the play was the fourth down play and the ball is not advanced past the first down marker then the defensive team would gain possession).
Field hockey
Field hockey is a team sport of the hockey family. The earliest origins of the game date back to the Middle Ages in England, Scotland, France and the Netherlands. The game can be played on a grass field, turf field or synthetic field as well as an indoor board surface. Each team plays with eleven players, including the goalie. Players use sticks made out of wood, carbon fibre, fibre glass or a combination of carbon fibre and fibre glass in different quantities (with the higher carbon fibre stick being more expensive and less likely to break) to hit a round, hard, plastic ball. The length of the stick depends on the player's individual height.
Field goal
A field goal (FG) is a means of scoring in American football and Canadian football. To score a field goal the team in possession of the ball must place kick, or drop kick, the ball through the goal, i.e., between the uprights and over the crossbar. American football requires that a field goal must only come during a play from scrimmage, while Canadian football retains open field kicks and thus field goals may be scored at any time from anywhere on the field and by any player. The vast majority of field goals, in both codes, are placed kicked. Drop kicked field goals were common in the early days of Gridiron football but are almost never done in modern times.
Comparison of Canadian football and rugby union
A comparison of Canadian football and rugby union is possible because of the games' shared origins, despite their dissimilarities. The most significant difference in play is the allowance of blocking for the ball carrier, which is to say preventing a defender from tackling the player with the ball. This rule in Canadian football allows top-flight teams to include hundreds of different plays in each and every match. It also slows the game down, causing frequent stoppages and less spontaneity in play. The laws against this in rugby union allow for each team to contest possession at all stages of a game.
