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.
There are two categories of kicks in football: On a kickoff, the ball is placed at the yard line of the kicking team in professional and college play and at the 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 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 and has touched the ground 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. If it is touched or recovered by the kicking team beyond this line, it becomes dead at the spot where it was touched.
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 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 their hat as a secondary signal.
Another set of officials, the chain crew , are responsible for moving the chains. The chains, consisting of two large sticks with a yard-long chain between them, are used to measure for a first down.
The chain crew stays on the sidelines during the game, but if requested by the officials they will briefly bring the chains on to the field to measure.
A typical chain crew will have at least three people — two members of the chain crew will hold either of the two sticks, while a third will hold the down marker.
The down marker, a large stick with a dial on it, is flipped after each play to indicate the current down, and is typically moved to the approximate spot of the ball.
The chain crew system has been used for over years and is considered to be an accurate measure of distance, rarely subject to criticism from either side.
Football is a full-contact sport, and injuries are relatively common. Most injuries occur during training sessions, particularly ones that involve contact between players.
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 mouthguards.
The most common types of injuries are strains , sprains , bruises , fractures, dislocations , and concussions. Repeated concussions and possibly sub-concussive head impacts  can increase a person's risk in later life for CTE chronic traumatic encephalopathy and mental health issues such as dementia , Parkinson's disease , and depression.
A study performed by the VA Boston Healthcare System and Boston University's school of medicine found that tackle football before age 12 was correlated with earlier onset of symptoms of CTE, but not with symptom severity.
More specifically, each year a player played tackle football under age 12 predicted earlier onset of cognitive, behavioral, and mood problems by an average of two and a half years.
College football is the third-most popular sport in the United States, behind professional baseball and professional football.
High school football is the most popular sport in the United States played by boys; over 1. 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.
Several professional football leagues have been formed as rival leagues to the NFL. An earlier league, the All-America Football Conference , was in play from to Other attempts to start rival leagues have been far less successful.
The World Football League WFL played for two seasons, in and , 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.
American football leagues exist throughout the world, but the game has yet to achieve the international success and popularity of baseball and basketball.
The league's championship game is the Eurobowl. 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 Summer Olympics. Large team sizes are an additional difficulty, due to the Olympics' set limit of 10, athletes and coaches.
American football also has the issue of global visibility. Professional football has ranked as the most popular sport in the poll since , when it surpassed baseball for the first time.
In a study, the NCAA estimated there were around 1. American football also plays a significant role in American culture.
The day on which the Super Bowl is held is considered a de facto national holiday ,  and in parts of the country like Texas , the sport has been compared to a religion.
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".
The safety of the sport has also sparked national controversy in American popular culture. It is often received as "overly aggressive", and defamiliarized in popular culture.

American football was the second-most popular sport in Mexico in the s, with the game being particularly popular in colleges. American football is the fifth most popular sport in Mexico and the country has the highest rating of the NFL outside the United States.
Japan was introduced to the sport in 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 [update] , there are more than high school football teams in Japan, with over 15, participants, and over teams play in the Kantoh Collegiate Football Association KCFA.
Europe is a major target for expansion of the game by football organizers. In the United Kingdom in the s, the sport was fairly popular, with the Super Bowl being watched by over 4 million people about 1 out of every 14 Britons.
The sport's popularity faded over the s, 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.
Super Bowl viewership has also rebounded, with over 4. 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, registered amateur players.
But in these countries American football has not yet reached the same level of popularity it has, for example, in North America. Brazil's audience is the 3rd of the world, behind only Mexico and United States.
Rumors were that a Pro Bowl edition could be held there. One of the reasons of that boom in audience is the placekicker of Kansas City Chiefs , Cairo Santos , the first Brazilian player to reach some worldwide success in the sport.
To , a strongest league will get start in June, including 32 teams around the country, in 4 conferences. The recent born team already won his state championship, and for the Brazilian top league already has signed with former NFL's player Nic Harris.

Canadian football , 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.
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.
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.
There are several non-contact variants of American football, such as flag football. 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.

During the playoffs, the game will continue with as many overtime periods as needed to decide a winner.
If the game is tied after each team has had the ball once in overtime, the first team to score wins. The game ends when one team scores, and the other team fails to score as many points during its chance.
Most of the game is played on yards in the middle. It is divided by 20 lines drawing every 5 yards. The field has two other sets of markings, running between the two end zones along the length of the field, known as "hashmarks".
All plays must start between the hashmarks—if the last play ended outside the hashmarks, the ball is moved to the nearest hashmark.
At the ends of the field there are scoring areas, called the end zones. There are also two yellow poles on the end of each field called uprights.
Sometimes, if the team can not score a touchdown they might want to kick it through the uprights for three points.
The uprights are also used for scoring one point after a team scored a touchdown. There are many types of players on a football team.
For the offensive part of the team, a quarterback throws the football to wide receivers while offensive linemen block to protect him from defensive players.
The offensive linemen also block when a running back runs to advance the football. Players on the Defensive line , a linebacker , and defensive backs cornerbacks and American football safeties attempt to tackle the offensive player who carries the football.
Some team members only play during certain times. These players belong to the Special Teams. The kicker can kick the ball to the other team or between the uprights, while the placeholder holds the ball steady.
The kick returner runs the ball down the field in an attempt to score points after catching the ball.
A touchdown is achieved when a player has legal possession of the ball and the ball crosses an imaginary vertical plane above the opposing team's goal line.
After a touchdown, the scoring team attempts a try for 1 or 2 points see below. A successful touchdown is signaled by an official extending both arms vertically above the head.
A field goal is scored when the ball is place kicked between the goal posts behind the opponent's end zone. The most common type of kick used is the place kick.
For a place kick, the ball must first be snapped to a placeholder, who holds the ball upright on the ground with his fingertip so that it may be kicked.
Three points are scored if the ball crosses between the two upright posts and above the crossbar and remains over.
Immediately following a touchdown, the scoring team can attempt to kick the ball between the goal posts for 1 extra point. The team can also run or pass the ball into the end zone for 2 points.
This is not done very often although it does happen. A safety is scored if a player causes the ball to become dead in his own end zone.
When this happens two points are awarded to the opposing usually defending team. This can happen if a player is either downed or goes out of bounds in the end zone while carrying the ball.
It can also happen if he fumbles the ball, and it goes out of bounds in the end zone. A safety is also awarded to the defensive team if the offensive team commits a foul which is enforced in its own end zone.
Exhibition season better known as Pre-Season is in August. In the exhibition season, the teams get ready for the regular season by having training.
Teams have practices to help the team get better and see who will make the team. All of the teams play 4 games before the regular season starts, and the games do not change what team gets to the post season.
Because of it, teams do not use their best players much, and use the games as more practice. The 32 NFL teams are divided into two conferences: Each of them is divided in four divisions:
