There are opposing views on the necessity of competition as a defining element of a sport, with almost all professional sport involving competition, and governing bodies requiring competition as a prerequisite of recognition by the International Olympic Committee (I.O.C) or Sport Accord.
Other bodies advocate widening the definition of sport to include all physical activity. For instance, the Council of Europe include all forms of physical exercise, including those completed just for fun.
In order to widen participation, and reduce the impact of losing on less able participants, there has been an introduction of non-competitive physical activity to traditionally competitive events such as school sports days, although moves like this are often controversial.
In competitive events, participants are graded or classified based on their "result" and often divided into groups of comparable performance, (e.g. gender, weight and age). For each group, the first in the list will usually be the "winner". The measurement of the result may be objective or subjective, and corrected with "handicaps" or penalties. In a race, for example, the time to complete the course is an objective measurement. In gymnastics or diving the result is decided by a panel of judges, and therefore subjective. There are many shades in between, like boxing or mixed martial arts, where victory is assigned by judges if neither competitor has lost at the end of the match time.
Sport can be undertaken on an amateur, professional or semi-professional basis, depending on whether participants are incentivised for participation (usually through payment of a wage or salary).
The popularity of spectator sport as a recreation for non-participants has led to sport becoming a major business in its own right, and this has incentivised a high paying professional sport culture, where high performing participants are rewarded with pay far in excess of average wages, which can run into millions of dollars.
Some sports, or individual competitions within a sport, retain a policy of allowing only amateur sport. The Olympic Games started with a principle of amateur competition with those who practiced a sport professionally considered to have an unfair advantage over those who practiced it merely as a hobby. Following the 1988 games, the IOC decided to make all professional athletes eligible for the Olympics, with only boxing and wrestling still competed on an "amateur" basis, although this revolves around rules, and not payment.

Grassroots sport is a popular phrase which covers the amateur participation in sport at lower levels, normally without pretension towards higher achievement, and is in line with the "sport for all" mentality, where enjoyment is the primary reason for participation
The competition element of sport, along with the aesthetic appeal of some sports, result in the popularity of people attending to watch sport being played. This has led to the specific phenomenon of spectator sport.
Both amateur and professional sports attract spectators, both in person at the sport venue, and through broadcast mediums including radio, television and internet broadcast. Both attendance in person and viewing remotely can incur a sometimes substantial charge, such as an entrance ticket, or pay-per-view television broadcast.

It is common for popular sports to attract large broadcast audiences, leading to rival broadcasters bidding large amounts of money for the rights to show certain fixtures. The football World Cup attracts a global television audience of hundreds of millions; the 2006 final alone attracted an estimated worldwide audience of well over 700 million and the 2011 Cricket World Cup Final attracted an estimated audience of 135 million in India alone .
In the United States, the championship game of the NFL, the Super Bowl, has become one of the most watched television broadcasts of the year. Super Bowl Sunday is a defacto national holiday in America; the viewership being so great that in 2007 advertising space was reported as being sold at $2.6m for a 30-second slot.
The 1936 Summer Olympics held in Berlin was an illustration, perhaps best recognised in retrospect, where an ideology was developing which used the event to strengthen its spread through propaganda. The Berlin Olympics, which took place on August 1936, on the eve of World War II is a classical example of the symbiosis of the politics and sports. The Olympics were highly valuable to Nazi Germany for propaganda purposes. Germany used the Olympics to give of itself a peaceful image while it was very actively preparing the war, and they helped smooth the way to the racist anti-Semitism of the Holocaust.
When apartheid was the official policy in South Africa, many sports people, particularly in rugby union, adopted the conscientious approach that they should not appear in competitive sports there. Some feel this was an effective contribution to the eventual demolition of the policy of apartheid, others feel that it may have prolonged and reinforced its worst effects.
In the history of Ireland, Gaelic sports were connected with cultural nationalism. Until the mid 20th century a person could have been banned from playing Gaelic football, hurling, or other sports administered by the Gaelic Athletic Association (G.A.A) if she/he played or supported football, or other games seen to be of British origin. Until recently the G.A.A continued to ban the playing of football and rugby union at Gaelic venues. This ban is still enforced, but was modified to allow football and rugby to be played in Croke Park while Lansdowne Road was redeveloped into Aviva Stadium. Until recently, under Rule 21, the G.A.A also banned members of the British security forces and members of the RUC from playing Gaelic games, but the advent of the Good Friday Agreement in 1998 led to the eventual removal of the ban.
Nationalism is often evident in the pursuit of sports, or in its reporting: people compete in national teams, or commentators and audiences can adopt a partisan view. On occasion, such tensions can lead to violent confrontation among players or spectators within and beyond the sporting venue, as in the Football War. These trends are seen by many as contrary to the fundamental ethos of sports being carried on for its own sake and for the enjoyment of its participants.
A very famous case when sports and politics collided was the 1972 Olympics in Munich. Masked men entered the hotel of the Israeli olympic team and killed many of their men. This was known as the Munich massacre.
A study of US elections has shown that the result of sports events can affect the results. A study published in the Proceedings of the National Academy of Science showed that when the home team wins the game before the election, the incumbent candidates can increase their share of the vote by 1.5 percent. A loss had the opposite effect, and the effect is greater for higher-profile teams or unexpected wins and losses. The study authors concluded that the win made voters feel better about society, boosting votes for the incumbent, while losses made voters feel worse, sending votes to the challenger.

In American football, the winner is the team that has scored the most points at the end of the game. There are multiple ways to score in a football game.
The touchdown (TD), worth six points, is the most valuable scoring play in American football. A touchdown is scored when a live ball is advanced into, caught in, or recovered in the end zone of the opposing team. The scoring team then attempts a try or conversion, more commonly known as the point(s)-after-touchdown (PAT), which is a single scoring opportunity. A PAT is attempted from the two- or three-yard line, depending on the level of play. If scored by a placekick or dropkick through the goal posts, it is worth one point, and is typically called the extra point. If it is scored by what would normally be a touchdown, it is called the two-point conversion. and is worth two points. No points are awarded on a failed extra point or two-point conversion attempt. In general, the extra point is almost always successful in professional play and is only slightly less successful at amateur levels, while the two-point conversion is a much riskier play with a higher probability of failure; accordingly, extra point attempts are far more common than two-point conversion attempts.

A field goal (FG), worth three points, is scored when the ball is placekicked or drop kicked through the uprights and over the crossbars of the defense's goalposts. After a PAT attempt or successful field goal the scoring team must kick the ball off to the other team. A safety is scored when the ball carrier is tackled in his own end zone. Safeties are worth two points, which are awarded to the defense. In addition, the team that conceded the safety must kick the ball to the scoring team via a free kick.
Football games are played on a rectangular field that measures 120 yards (110 m) long and 53.33 yards (48.76 m) wide. Lines marked along the ends and sides of the field are known respectively as the end lines and side lines, and goal lines are marked 10 yards (9.1 m) inward from each end line. Weighted pylons are placed on the inside corner of the intersections of the goal lines and end lines.
White markings on the field identify the distance from the end zone. Inbound lines, or hash marks, are short parallel lines that mark off 1 yard (0.91 m) increments. Yard lines, which run the width of the field, are marked every 5 yards (4.6 m).

A one yard wide is placed at each end of the field; this line is marked at the center of the two-yard line in professional play and at the three-yard line in college play. Numerals that display the distance from the closest goal line in multiples of ten are placed on both sides of the field every ten yards.
Goalposts are at located at the center of the plane of each of the two end lines. The crossbar of these posts is ten feet (3 meters) above the ground, with vertical uprights at the end of the crossbar 18 feet 6 inches (6 m) apart for professional and collegiate play and 23 feet 4 inches (7 m) apart for high school play. The uprights extend vertically 35 feet on professional fields, a minimum of 10 yards on college fields, and a minimum of ten feet on high school fields. Goal posts are padded at the base, and orange ribbons are normally placed at the tip of each upright.

The football itself is an oval ball, similar to the balls used in rugby or Australian rules football. At all levels of play, the football is inflated to 12 1⁄2 to 13 1⁄2 pounds per square inch (psi) and weighs 14 to 15 ounces (397 to 425 grams); beyond that, the exact dimensions vary slightly. In professional play the ball has a long axis of 11 to 11 1⁄4 inches, a long circumference of 28 to 28 1⁄2 inches, and a short circumference of 21 to 21 1⁄4 inches, while in college and high school play the ball has a long axis of 10 7⁄8 to 11 7⁄16 inches, a long circumference of 27 3⁄4 to 28 1⁄2 inches, and a short circumference of 20 3⁄4 to 21 1⁄4 inches.
Duration and time stoppages Football games last for a total of 60 minutes in professional and college play and are divided into two halves of 30 minutes and four quarters of 15 minutes. High school football games are 48 minutes in length with two halves of 24 minutes and four quarters of 12 minutes. The two halves are separated by a halftime period, and the first and third quarters are also followed by a short break. Prior to the start of the game, the referee and team captains for each team meet at midfield for a coin toss. The visiting team is allowed to call 'heads' or 'tails'; the winner of the toss is allowed to decide from between choosing whether to receive or kick off the ball or choosing which goal they want to defend, but they can also defer their choice until the second half. The losing team, unless the winning team decides to defer, is allowed to choose the option the winning team did not select, and receives the option to receive, kick, or select a goal to defend to begin the second half. Most teams choose to receive or defer, because choosing to kick the ball to start the game would allow the other team to choose which goal to defend. Teams switch goals following the first and third quarters. If a down is in progress when a quarter ends, play continues until the down is completed.
Games last longer than their defined length due to play stoppages - the average NFL game lasts slightly over three hours. Time in a football game is measured by the game clock. An operator is responsible for starting, stopping and operating the game clock based on the direction of the appropriate official. A separate clock, the play clock, is used to determine if a delay of game infraction has been committed. If the play clock expires before the ball has been snapped or free-kicked, a delay of game foul is called on the offense. The play clock is set to 40 seconds in professional and college football and to 25 seconds in high school play or following certain administrative stoppages in the former levels of play.
Carolina Panthers quarterback Jake Delhomme (number 17) in the motion of throwing a forward pass.There are two main ways that the offense can advance the ball: running and passing. In a typical play, the quarterback calls the play, and the center passes the ball backwards and under his legs to the quarterback in a process known as the snap. The quarterback then either hands the ball off to a back, throws the ball or runs with it himself. The play ends when the player with the ball is tackled or goes out of bounds, or a pass hits the ground without a player having caught it. A forward pass can only be legally attempted if the passer is behind the line of scrimmage. In the NFL, a down also ends if the runner's helmet comes off.
The offense is given a series of four plays, known as downs. If the offense advances ten or more yards in the four downs, they are awarded a new set of four downs. If they fail to advance ten yards, possession of the football is turned over to the defense. In most situations, if the offense reaches their fourth down they will punt the ball to the other team, which forces them to begin their drive from further down the field; if they are in field goal range, they might also attempt to score a field goal. A group of officials, the chain crew, keeps track of both the downs and the distance measurements. On television, a yellow line is electronically superimposed on the field to show the first down line to the viewing audience.
Green Bay Packers Placekicker Mason Crosby attempts a field goal by kicking the ball from the hands of a holder. This is the standard method to score field goals or extra points.There are two categories of kicks in football: scrimmage kicks, which can be executed by the offensive team on any down from behind or on the line of scrimmage, and free kicks. The free kicks are the kickoff, which starts the first and third quarters and overtime and follows a try attempt or a successful field goal, and the safety kick, which follows a safety.
On a kickoff, the ball is placed at the 35-yard line of the kicking team in professional and college play and at the 40-yard line in high school play. The ball may be drop-kicked or place-kicked. If a place kick is chosen, the ball can be placed on the ground or on a tee, and a holder may be used in either case. On a safety kick, the kicking team kicks the ball from their own 20-yard line. They can punt, drop-kick or place-kick the ball, but a tee may not be used in professional play. Any member of the receiving team may catch or advance the ball, and the ball may be recovered by the kicking team once it has gone at least ten yards or has been touched by any member of the receiving team.
The three types of scrimmage kicks are place kicks, drop kicks, and punts. Only place kicks and drop kicks can score points. The place kick is the standard method used to score points, because the pointy shape of the football makes it difficult to reliably drop kick. Once the ball has been kicked from a scrimmage kick, it can be advanced by the kicking team only if it is caught or recovered behind the line of scrimmage. If it is touched or recovered by the kicking team beyond this line, it becomes dead at the spot where it was touched. The kicking team is prohibited from interfering with the receiver's opportunity to catch the ball, and the receiving team has the option of signaling for a fair catch. This prohibits the defense from blocking into or tackling the receiver, but the play ends as soon as the ball is caught and the ball may not be advanced.
Officials use the chains to measure for a first down. Here, the ball is just short of the pole and therefore short of a first down.Officials are responsible for enforcing game rules and monitoring the clock. All officials carry a whistle and wear black-and-white striped shirts and black hats except for the referee, whose hat is white. Each carries a weighted yellow flag that is thrown to the ground to signal that a foul has been called. An official who spots multiple fouls will throw his hat as a secondary signal. The seven officials on the field are each tasked with a different set of responsibilities:
A modern down indicator box is mounted on a pole and is used to mark the current line of scrimmage. The number on the marker is changed using a dial.

The seven officials on the field are each tasked with a different set of responsibilities:
- The referee is positioned behind and to the side of the offensive backs. He is charged with oversight and control of the game and is the authority on the score, the down number, and any and all rule interpretations in discussions between the other officials. He announces all penalties and discusses the infraction with the offending team's captain, monitors for illegal hits against the quarterback, makes requests for first-down measurements, and notifies the head coach whenever a player is ejected.
- The umpire is positioned in the defensive backfield. He watches play along the line of scrimmage to make sure that no more than 11 offensive players are on the field prior to the snap and that no offensive linemen are illegally downfield on pass plays. He monitors the contact between offensive and defensive linemen and calls most of the holding penalties. The umpire records the number of timeouts taken and the winner of the coin toss and the game score, assists the referee in situations involving possession of the ball close to the line of scrimmage, determines whether player equipment is legal, and dries wet balls prior to the snap if a game is played in rain.
- The back judge is positioned deep in the defensive backfield, behind the umpire. He ensures that the defensive team has no more than 11 players on the field and determines whether catches are legal, whether field goal or extra point attempts are good, and whether a pass interference violation occurred.
- The head linesman is positioned on one end of the line of scrimmage. He watches for any line-of-scrimmage and illegal use-of-hands violations and assists the line judge with illegal shift or illegal motion calls. The head linesman also rules on out-of-bounds calls that happen on his side of the field, oversees the chain crew and marks the forward progress of a runner when a play has been whistled dead.
A modern down indicator box is mounted on a pole and is used to mark the current line of scrimmage. The number on the marker is changed using a dial.
- The side judge is positioned twenty yards downfield of the head linesman. He mainly duplicates the functions of the back judge.
- The line judge is positioned on the end of the line of scrimmage, opposite the head linesman. He supervises player substitutions, the line of scrimmage during punts, and game timing. He notifies the referee when time has expired at the end of a quarter and notifies the head coach of the home team when five minutes remain for halftime. In the NFL, the line judge also alerts the referee when two minutes remain in the half. If the clock malfunctions or becomes inoperable, the line judge becomes the official timekeeper.
- The field judge is positioned twenty yards downfield from the line judge. He monitors and controls the play clock, counts the number of defensive players on the field, and watches for offensive pass interference and illegal use-of-hands violations by offensive players. He also makes decisions regarding catches, recoveries, the ball spot when a player goes out of bounds, and illegal touching of fumbled balls that have crossed the line of scrimmage.
A player wearing a helmet. Shoulder pads and thigh pads are visible under his uniform.Football is a full-contact sport, and injuries are relatively common. Most injuries occur during training sessions, particularly ones that involve contact between players.To try to prevent injuries, players are required to wear a set of equipment. At a minimum players must wear a football helmet and a set of shoulder pads, but individual leagues may require additional padding such as thigh pads and guards, knee pads, chest protectors, and mouth guards. Most injuries occur in the lower extremities, particularly in the knee, but a significant number also affect the upper extremities. The most common types of injuries are strains, sprains, bruises, fractures, dislocations, and concussions. Repeated concussions can increase a person's risk in later life for chronic traumatic encephalopathy and mental health issues such as dementia, Parkinson's disease, and depression. Concussions are often caused by helmet-to-helmet or upper-body contact between opposing players, although helmets have prevented more serious injuries such as skull fractures. Various programs are aiming to reduce concussions by reducing the frequency of helmet-to-helmet hits; USA Football's "Heads Up Football" program is aiming to reduce concussions in youth football by teaching coaches and players about the signs of a concussion, the proper way to wear football equipment and ensure it fits, and proper tackling methods that avoid helmet-to-helmet contact.
Leagues and tournaments The National Football League (NFL) and the National Collegiate Athletic Association (NCAA) are the most popular football leagues in the United States. The National Football League was founded in 1920 and has since become the largest and most popular sport in the United States. The NFL has the highest average attendance of any sporting league in the world, with an average attendance of almost 70,000 persons during the 2011 NFL Season. The NFL championship game is called the Super Bowl, and is among the biggest events in club sports worldwide. It is played between the champions of the National Football Conference (NFC) and the American Football Conference (AFC), and its winner is awarded the Vince Lombardi Trophy.
College football is the third-most popular sport in the United States, behind professional baseball and professional football. The NCAA, the largest collegiate organization, is divided into three Divisions: Division I, Division II and Division III. Division I football is further divided into two subdivisions: the Football Bowl Subdivision (FBS) and the Football Championship Subdivision (FCS). The champions of each level of play are determined through NCAA-sanctioned playoff systems; while the champion of Division I-FBS was historically determined by various polls and ranking systems, the subdivision adopted a four-team playoff system in 2014.
High school football is the most popular sport in the United States played by boys; over 1.1 million boys participated in the sport from 2007 to 2008 according to a survey by the National Federation of State High School Associations (NFHS). The NFHS is the largest organization for high school football, with member associations in all 50 states as well as the District of Columbia. USA Football is the governing body for youth and amateur football, and Pop Warner Little Scholars is the largest organization for youth football.
Rival professional leaguesSeveral professional football leagues have been formed as rival leagues to the NFL. The most successful rival league was the American Football League (AFL), which existed from 1960 to 1969. The AFL became a significant rival in 1964 before signing a five-year, US$36 million television deal with NBC. AFL teams began to sign NFL players to contracts, and the league's popularity grew to challenge that of the NFL. The two leagues merged in the 1970 season, and all AFL teams joined the NFL. An earlier league, the All-America Football Conference, was in play from 1946 to 1949. After the league dissolved, two AAFC teams, the Cleveland Browns and the San Francisco 49ers, became members of the NFL; another member, the Baltimore Colts joined the league, but folded after just a year in the NFL.
Other attempts to start rival leagues have been far less successful. The World Football League (WFL) played for two seasons, in 1974 and 1975, but faced monetary issues so severe that the league could not pay its players. In its second and final season the WFL attempted to establish a stable credit rating, but the league disbanded before its second season could be completed. The United States Football League (USFL) operated for three seasons from 1983 to 1985 but collapsed due to poor business decisions and monetary problems. A subsequent USD $1.5 billion antitrust lawsuit against the NFL was successful in court, but the league was awarded only three dollars in damages. The XFL was created in 2001 by Vince McMahon and lasted for only one season. Despite television contracts with NBC and UPN and high expectations, the XFL suffered from poor television ratings and a low quality of play. The United Football League (UFL) began in 2009, but folded after suspending its 2012 season, due to financial issues.

The Players with one of the youth divisions of the Borregos Salvajes football program of the Monterrey Institute of Technology and Higher Education, Mexico City.American football leagues exist throughout the world, but the game has yet to achieve the international success and popularity of baseball and basketball. NFL Europa, the developmental league of the NFL, operated from 1991 to 1992 and then from 1995 to 2007. At the time of its closure, NFL Europa had five teams based in Germany and one in the Netherlands.
The European Football League (EFL), run by the European Federation of American Football (EFAF), is an annual invitational tournament between the champions or co-champions of competitions run by EFAF members. The league's championship game is the Eurobowl. Other EFAF tournaments include the EFAF Cup, played between the top teams from national leagues in a similar manner to the UEFA Cup, the Atlantic Cup, played between teams from the Atlantic region of Europe, and the Challenge Cup, played between teams from newer federations that are not eligible to play in the EFL or EFAF Cup. American football federations are also present in Asia, Oceania, and Pan America, and a total of 64 national football federations exist as of July 2012.

American football federations are also present in Asia, Oceania, and Pan America, and a total of 64 national football federations exist as of July 2012.
The International Federation of American Football (IFAF), an international body composed of American football federations, runs tournaments such as the IFAF World Championship, which is held every four years since 1999, the IFAF Women's World Championship, the IFAF U-19 World Championship and the Flag Football World Championship. The IFAF also organizes the annual International Bowl game. At the international level, Canada, Mexico, and Japan are considered to be second-tier, while Austria, Germany, and France would rank among a third tier. All of these countries rank far below the United States, which is dominant at the international level.
Football is not an Olympic sport, but it was a demonstration sport at the 1932 Summer Olympics. The IFAF has received provisional recognition from the International Olympic Committee (IOC), and a vote on making it an Olympic sport could be held as early as 2017. Several major obstacles hinder the IFAF goal of achieving status as an Olympic sport, such as the predominant participation of men in international play and the short three-week Olympic schedule. Large team sizes are an additional difficulty, due to the Olympics' set limit of 10,500 athletes and coaches. Although these issues are similar to those that rugby union faced prior to being admitted into the Olympics in the form of rugby sevens, a modified version of the sport, American football also has the issue of global visibility. Nigel Melville, the CEO of USA Rugby, noted that while rugby union has a major international presence through the International Rugby Board, "American football is recognized globally as a sport, but it's not played globally". In order to solve these concerns, major effort has been put into promoting flag football, a modified version of American football, at the international level.
Popularity and cultural impact According to ESPN.com's Sean McAdam, "Baseball is still called the national pastime, but football is by far the more popular sport in American society". In a 2014 poll conducted by Harris Interactive, professional football ranked as the most popular sport, and college football ranked third behind only professional football and baseball; 46% of participants ranked some form of the game as their favorite sport. Professional football has anked as the most popular sport in the poll since 1985, when it surpassed baseball for the first time. Professional football is most popular among those who live in the eastern United States and rural areas, while college football is most popular in the southern United States and among people with graduate and post-graduate degrees. Football is also the most-played sport by high school and college athletes in the United States. In a 2012 study, the NCAA estimated there were around 1.1 million high school football players and nearly 70,000 college football players in the United States; in comparison, the second-most played sport, basketball, had around 1 million participants in high school and 34,000 in college. The Super Bowl is the most popular single-day sporting event in the United States, and is among the biggest club sporting events in the world in terms of TV viewership. The NFL makes approximately $10 billion annually. Super Bowl games account for seven of the top eight most-watched broadcasts in American history; the most recent Super Bowl, Super Bowl XLIX, was watched by a record 114.4 million Americans.
Football also plays a significant role in American culture. The Super Bowl is considered a de facto national holiday, and in parts of the country like Texas, the sport has been compared to a religion. Football is also linked to other holidays; New Year's Day is traditionally the date for several college football bowl games, including the Rose Bowl. However, if New Year's Day is on a Sunday, the bowl games are moved to another date to not conflict with the typical NFL Sunday schedule. Thanksgiving football is an American tradition, hosting many high school, college, and professional games. Steve Deace of USA Today wrote that Americans are passionate about football "because it embodies everything we love about American exceptionalism. Merit is rewarded, not punished. Masculinity is celebrated, not feminized. People of various beliefs and backgrounds — a melting pot, if you will — must unify for a common goal for the team to be successful". Implicit rules such as playing through pain and sacrificing for the better of the team are promoted in football culture.
In Canada, the game has a significant following - according to a 2013 poll, 21% of respondents said they followed the NFL "very closely" or "fairly closely", making it the third-most followed league behind the National Hockey League (NHL) and Canadian Football League (CFL). American football also has a long history in Mexico, which was introduced to the sport in 1896. American football was the second-most popular sport in Mexico in the 1950s, with the game being particularly popular in colleges. The Los Angeles Times notes that the NFL claims over 16 million fans in Mexico, which places the country third behind the US and Canada. American football is played in Mexico both professionally and as part of the college sports system. Japan was introduced to the sport in 1934 by Paul Rusch, a teacher and Christian missionary who helped establish football teams at three universities in Tokyo. Play was halted during World War II, but began to grow in popularity again after the war. As of 2010, there are more than 400 high school football teams in Japan, with over 15,000 participants, and over 100 teams play in the Kantoh Collegiate Football Association (KCFA). The college champion plays the champion of the X-League (a semi-pro league where teams are financed by corporations) in the Rice Bowl to determine Japan's national champion.
Outside of North America and Japan, Europe is a major target for expansion of the game by football organizers. The sport is played in European countries such as Switzerland, which has American football clubs in every major city and Germany, where the sport has around 45,000 registered amateur players. The sport is also established in the United Kingdom. In the 1980s, the sport was fairly popular, with the 1986 Super Bowl being watched by over 4 million people (about 1 out of every 14 Britons). The sport's popularity faded over the 1990s, coinciding with the establishment of the Premier League. According to BBC America, there is a "social stigma" surrounding American football in the UK, with many Brits feeling the sport has no right to call itself 'football' due to the small emphasis on kicking. Nonetheless, the sport has retained a significant following in the United Kingdom; the NFL operates a media network in the country, and since 2007 has hosted the NFL International Series in London. Super Bowl viewership has also rebounded, with over 4.4 million Britons watching Super Bowl XLVI.

The predominant form of football in Canada, is closely related to American football - both sports developed from rugby, and the two sports are considered to be the chief variants of gridiron football. Although the two games share a similar set of rules, there are several key rule differences: for example, in Canadian football the field measures 150 yards (137 m) by 65 (59 m) yards, including two 20-yard end zones (for a distance between goal lines of 110 yards), teams have three downs instead of four, there are twelve players on each side instead of eleven, fair catches are not allowed, and a rouge, worth a single point is scored if the offensive team kicks the ball out of the defense's end zone. The Canadian Football League (CFL) is the major Canadian league and is the second-most popular sporting league in Canada, behind only the National Hockey League.
A major variant of football is arena football, played by the Arena Football League (AFL). Arena football has eight-player teams and uses an indoor field 50 yards (46 m) in length, excluding end zones, and 28.3 yards (25.9 m) wide. Punting is illegal, and kickoffs are attempted from the goal line. Large overhead nets deflect forward passes and kicks that hit them, and deflected kicks are live balls that may be recovered by either team.
Below the Arena Football League are what New York Times writer Mike Tanier described as the "most minor of minor leagues:" indoor football leagues. Like in arena football, teams in indoor football leagues play in arenas, but games are only attended by a small number of fans, and most players are semi-professional athletes. Indoor football leagues are unstable, with franchises regularly moving from one league to another or merging with other teams, and teams or entire leagues dissolving entirely. The Indoor Football League, Southern Indoor Football League, Ultimate Indoor Football League, Continental Indoor Football League and American Professional Football League are examples of prominent indoor leagues.
There are several non-contact variants of American football, such as flag football. In flag football the ball carrier is not tackled; instead, defenders aim to pull a flag tied around his waist. Another variant, touch football, simply requires the ball carrier to be touched to be considered downed. A game of touch football may require that the player be touched with either one or two hands to be considered down, depending on the rules used.dit.

In the mid-1850s, a baseball craze hit the New York metropolitan area. By 1856, local journals were referring to baseball as the "national pastime" or "national game". A year later, sixteen area clubs formed the sport's first governing body, the National Association of Base Ball Players. In 1858 in Corona, Queens New York, at the Fashion Race Course, the first games of baseball to charge admission took place. The games, which took place between the all stars of Brooklyn, including players from the Brooklyn Atlantics, Excelsior of Brooklyn, Putnams and Eckford of Brooklyn, and the All Stars of New York (Manhattan), including players from the New York Knickerbockers, Gothams (predecessors of the San Francisco Giants), Eagles and Empire, are commonly believed to be the first all-star baseball games. In 1863, the organization disallowed putouts made by catching a fair ball on the first bounce. Four years later, it barred participation by African Americans. The game's commercial potential was developing: in 1869 the first fully professional baseball club, the Cincinnati Red Stockings, was formed and went undefeated against a schedule of semipro and amateur teams. The first professional league, the National Association of Professional Base Ball Players, lasted from 1871 to 1875; scholars dispute its status as a major league.
The more formally structured National League was founded in 1876. As the oldest surviving major league, the National League is sometimes referred to as the "senior circuit". Several other major leagues formed and failed. In 1884, African American Moses Walker (and, briefly, his brother Welday) played in one of these, the American Association. An injury ended Walker's major league career, and by the early 1890s, a gentlemen's agreement in the form of the baseball color line effectively barred black players from the white-owned professional leagues, major and minor. Professional Negro leagues formed, but quickly folded. Several independent African American teams succeeded as barnstormers. Also in 1884, overhand pitching was legalized. In 1887, softball, under the name of indoor baseball or indoor-outdoor, was invented as a winter version of the parent game. Virtually all of the modern baseball rules were in place by 1893; the last major change—counting foul balls as strikes—was instituted in 1901. The National League's first successful counterpart, the American League, which evolved from the minor Western League, was established that year. The two leagues, each with eight teams, were rivals that fought for the best players, often disregarding each other's contracts and engaging in bitter legal disputes.
The New York Giants baseball team, 1913. Fred Merkle, sixth in line, committed a base running gaffe in a crucial 1908 game that became famous as Merkle's Boner.A modicum of peace was eventually established, leading to the National Agreement of 1903. The pact formalized relations both between the two major leagues and between them and the National Association of Professional Base Ball Leagues, representing most of the country's minor professional leagues. The World Series, pitting the two major league champions against each other, was inaugurated that fall, albeit without express major league sanction: The Boston Americans of the American League defeated the Pittsburgh Pirates of the National League. The next year, the series was not held, as the National League champion New York Giants, under manager John McGraw, refused to recognize the major league status of the American League and its champion. In 1905, the Giants were National League champions again and team management relented, leading to the establishment of the World Series as the major leagues' annual championship event.
As professional baseball became increasingly profitable, players frequently raised grievances against owners over issues of control and equitable income distribution. During the major leagues' early decades, players on various teams occasionally attempted strikes, which routinely failed when their jobs were sufficiently threatened. In general, the strict rules of baseball contracts and the reserve clause, which bound players to their teams even when their contracts had ended, tended to keep the players in check. Motivated by dislike for particularly stingy owner Charles Comiskey and gamblers' payoffs, real and promised, members of the Chicago White Sox conspired to throw the 1919 World Series. The Black Sox Scandal led to the formation of a new National Commission of baseball that drew the two major leagues closer together. The first major league baseball commissioner, Kenesaw Mountain Landis, was elected in 1920. That year also saw the founding of the Negro National League; the first significant Negro league, it would operate until 1931. For part of the 1920s, it was joined by the Eastern Colored League.
Compared with the present, professional baseball in the early 20th century was lower-scoring and pitchers, the likes of Walter Johnson and Christy Mathewson, were more dominant. The "inside game", which demanded that players "scratch for runs", was played much more aggressively than it is today: the brilliant and often violent Ty Cobb epitomized this style. The so-called dead-ball era ended in the early 1920s with several changes in rule and circumstance that were advantageous to hitters. Strict new regulations governing the ball's size, shape and composition along with a new rule officially banning the spitball, along with other pitches that depended on the ball being treated or roughed-up with foreign substances after the death of Ray Chapman who was hit by a pitch in August 1920, coupled with superior materials available after World War I, resulted in a ball that traveled farther when hit. The construction of additional seating to accommodate the rising popularity of the game often had the effect of bringing the outfield fences closer in, making home runs more common. The rise of the legendary player Babe Ruth, the first great power hitter of the new era, helped permanently alter the nature of the game. The club with which Ruth set most of his slugging records, the New York Yankees, built a reputation as the majors' premier team. In the late 1920s and early 1930s, St. Louis Cardinals general manager Branch Rickey invested in several minor league clubs and developed the first modern "farm system". A new Negro National League was organized in 1933; four years later, it was joined by the Negro American League. The first elections to the Baseball Hall of Fame took place in 1936. In 1939 Little League Baseball was founded in Pennsylvania. By the late 1940s, it was the organizing body for children's baseball leagues across the United States.
The New York Giants baseball team, 1913. Fred Merkle, sixth in line, committed a base running gaffe in a crucial 1908 game that became famous as Merkle's Boner.A modicum of peace was eventually established, leading to the National Agreement of 1903. The pact formalized relations both between the two major leagues and between them and the National Association of Professional Base Ball Leagues, representing most of the country's minor professional leagues. The World Series, pitting the two major league champions against each other, was inaugurated that fall, albeit without express major league sanction: The Boston Americans of the American League defeated the Pittsburgh Pirates of the National League. The next year, the series was not held, as the National League champion New York Giants, under manager John McGraw, refused to recognize the major league status of the American League and its champion. In 1905, the Giants were National League champions again and team management relented, leading to the establishment of the World Series as the major leagues' annual championship event.
As professional baseball became increasingly profitable, players frequently raised grievances against owners over issues of control and equitable income distribution. During the major leagues' early decades, players on various teams occasionally attempted strikes, which routinely failed when their jobs were sufficiently threatened. In general, the strict rules of baseball contracts and the reserve clause, which bound players to their teams even when their contracts had ended, tended to keep the players in check. Motivated by dislike for particularly stingy owner Charles Comiskey and gamblers' payoffs, real and promised, members of the Chicago White Sox conspired to throw the 1919 World Series. The Black Sox Scandal led to the formation of a new National Commission of baseball that drew the two major leagues closer together. The first major league baseball commissioner, Kenesaw Mountain Landis, was elected in 1920. That year also saw the founding of the Negro National League; the first significant Negro league, it would operate until 1931. For part of the 1920s, it was joined by the Eastern Colored League.
Compared with the present, professional baseball in the early 20th century was lower-scoring and pitchers, the likes of Walter Johnson and Christy Mathewson, were more dominant. The "inside game", which demanded that players "scratch for runs", was played much more aggressively than it is today: the brilliant and often violent Ty Cobb epitomized this style. The so-called dead-ball era ended in the early 1920s with several changes in rule and circumstance that were advantageous to hitters. Strict new regulations governing the ball's size, shape and composition along with a new rule officially banning the spitball, along with other pitches that depended on the ball being treated or roughed-up with foreign substances after the death of Ray Chapman who was hit by a pitch in August 1920, coupled with superior materials available after World War I, resulted in a ball that traveled farther when hit.

Jackie Robinson in 1945, with the era's Kansas City Royals, a barnstorming squad associated with the Negro American League's Kansas City Monarchs With America's entry into World War II, many professional players had left to serve in the armed forces. A large number of minor league teams disbanded as a result and the major league game seemed under threat as well. Chicago Cubs owner Philip K. Wrigley led the formation of a new professional league with women players to help keep the game in the public eye – the All-American Girls Professional Baseball League existed from 1943 to 1954. The inaugural College World Series was held in 1947, and the Babe Ruth League youth program was founded. This program soon became another important organizing body for children's baseball. The first crack in the unwritten agreement barring blacks from white-controlled professional ball occurred the previous year: Jackie Robinson was signed by the National League's Brooklyn Dodgers—where Branch Rickey had become general manager—and began playing for their minor league team in Montreal. In 1947, Robinson broke the major leagues' color barrier when he debuted with the Dodgers. Larry Doby debuted with the American League's Cleveland Indians the same year. Latin American players, largely overlooked before, also started entering the majors in greater numbers. In 1951, two Chicago White Sox, Venezuelan-born Chico Carrasquel and black Cuban-born Minnie Miñoso, became the first Hispanic All-Stars.
Facing competition as varied as television and football, baseball attendance at all levels declined. While the majors rebounded by the mid-1950s, the minor leagues were gutted and hundreds of semipro and amateur teams dissolved.Integration proceeded slowly: by 1953, only six of the 16 major league teams had a black player on the roster. That year, the Major League Baseball Players Association was founded. It was the first professional baseball union to survive more than briefly, but it remained largely ineffective for years. No major league team had been located west of St. Louis until 1958, when the Brooklyn Dodgers and New York Giants relocated to Los Angeles and San Francisco, respectively. The majors' final all-white bastion, the Boston Red Sox, added a black player in 1959. With the integration of the majors drying up the available pool of players, the last Negro league folded the following year. In 1961, the American League reached the West Coast with the Los Angeles Angels expansion team, and the major league season was extended from 154 games to 162. This coincidentally helped Roger Maris break Babe Ruth's long-standing single-season home run record, one of the most celebrated marks in baseball. Along with the Angels, three other new franchises were launched during 1961–62. With this, the first major league expansion in 60 years, each league now had ten teams.
A standard adult football match consists of two periods of 45 minutes each, known as halves. Each half runs continuously, meaning that the clock is not stopped when the ball is out of play. There is usually a 15-minute half-time break between halves. The end of the match is known as full-time. The referee is the official timekeeper for the match, and may make an allowance for time lost through substitutions, injured players requiring attention, or other stoppages. This added time is called additional time in FIFA documents, but is most commonly referred to as stoppage time or injury time, while loss time can also be used as a synonym. The duration of stoppage time is at the sole discretion of the referee. The referee alone signals the end of the match. In matches where a fourth official is appointed, toward the end of the half the referee signals how many minutes of stoppage time he intends to add. The fourth official then informs the players and spectators by holding up a board showing this number. The signalled stoppage time may be further extended by the referee. Added time was introduced because of an incident which happened in 1891 during a match between Stoke and Aston Villa.

Trailing 1–0 and with just two minutes remaining, Stoke were awarded a penalty. Villa's goalkeeper kicked the ball out of the ground, and by the time the ball had been recovered, the 90 minutes had elapsed and the game was over. The same law also stands that the duration of either half is extended until the penalty kick to be taken or retaken is completed, thus no game shall end with a penalty to be taken.
Some football competitions use a penalty shootout to decide the winner if a match ends as a drawIn league competitions, games may end in a draw. In knockout competitions where a winner is required various methods may be employed to break such a deadlock, some competitions may invoke replays. A game tied at the end of regulation time may go into extra time, which consists of two further 15-minute periods. If the score is still tied after extra time, some competitions allow the use of penalty shootouts (known officially in the Laws of the Game as "kicks from the penalty mark") to determine which team will progress to the next stage of the tournament. Goals scored during extra time periods count toward the final score of the game, but kicks from the penalty mark are only used to decide the team that progresses to the next part of the tournament (with goals scored in a penalty shootout not making up part of the final score).
In competitions using two-legged matches, each team competes at home once, with an aggregate score from the two matches deciding which team progresses. Where aggregates are equal, the away goals rule may be used to determine the winners, in which case the winner is the team that scored the most goals in the leg they played away from home. If the result is still equal, extra time and potentially a penalty shootout are required.
In the late 1990s and early 2000s, the IFAB experimented with ways of creating a winner without requiring a penalty shootout, which was often seen as an undesirable way to end a match. These involved rules ending a game in extra time early, either when the first goal in extra time was scored (golden goal), or if one team held a lead at the end of the first period of extra time (silver goal). Golden goal was used at the World Cup in 1998 and 2002. The first World Cup game decided by a golden goal was France's victory over Paraguay in 1998. Germany was the first nation to score a golden goal in a major competition, beating Czech Republic in the final of Euro 1996. Silver goal was used in Euro 2004. Both these experiments have been discontinued by IFAB
