137-529: The Circle City Classic is an annual American football game featuring two historically black colleges/universities (HBCUs) and played in Indianapolis, Indiana . The event was established in 1984 by Indiana Black Expo and has been played every year except 2020, when it was canceled due to the COVID-19 pandemic . No game was played for the 2022 Circle City Classic. The game was held from 1984 to 2007 in
274-422: A gridiron in appearance. Other major rule changes included a reduction of the field size to 110 by 53 + 1 ⁄ 3 yards (100.6 m × 48.8 m) and the adoption of a scoring system that awarded four points for a touchdown, two for a safety and a goal following a touchdown , and five for a goal from the field . Additionally, tackling below the waist was legalized, and a static line of scrimmage
411-403: A halftime period, and the first and third quarters are followed by a short break. Before the game starts, the referee and each team's captain meet at midfield for a coin toss . The visiting team can call either "heads" or "tails"; the winner of the toss chooses whether to receive or kick off the ball or which goal they wish to defend. They can defer their choice until the second half. Unless
548-563: A 0–0 tie. The Army–Navy game of 1893 saw the first documented use of a football helmet by a player in a game. Joseph M. Reeves had a crude leather helmet made by a shoemaker in Annapolis and wore it in the game after being warned by his doctor that he risked death if he continued to play football after suffering an earlier kick to the head. In 1879, the University of Michigan became the first school west of Pennsylvania to establish
685-401: A 10-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,
822-463: A 56-game undefeated streak that included a 1902 trip to play in the first college football bowl game , which later became the Rose Bowl Game . During this streak, Michigan scored 2,831 points while allowing only 40. Organized intercollegiate football was first played in the state of Minnesota on September 30, 1882, when Hamline was convinced to play Minnesota . Minnesota won 2 to 0. It
959-525: 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 the carrier's 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 + 1 ⁄ 3 yards (48.8 m) wide. Lines marked along
1096-514: A college football team. On May 30, 1879, Michigan beat Racine College 1–0 in a game played in Chicago. The Chicago Daily Tribune called it "the first rugby-football game to be played west of the Alleghenies ." Other Midwestern schools soon followed suit, including the University of Chicago , Northwestern University , and the University of Minnesota . The first western team to travel east
1233-528: A common draft that would take place each year, and it instituted an annual World Championship game to be played between the champions of each league. This championship game began play at the end of the 1966 season. Once the merger was completed, it was no longer a championship game between two leagues and reverted to the NFL championship game, which came to be known as the Super Bowl . College football maintained
1370-598: A feat the Professional Football Researchers Association compared to "selling refrigerators to Eskimos ". Princeton, Harvard, Yale, and Columbia then agreed to intercollegiate 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. Yale player Walter Camp , now regarded as
1507-453: A field goal instead. 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. 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

#17327801356101644-428: A game between Yale and Princeton, both teams 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. This "block game" proved extremely unpopular with both teams' spectators and fans. A rule change was necessary to prevent this strategy from taking hold, and a reversion to the scrum was considered. However, Camp successfully proposed
1781-598: A game for the Allegheny Athletic Association against the Pittsburgh Athletic Club . This is the first recorded instance of a player being paid to participate in a game of American football , although many athletic clubs in the 1880s offered indirect benefits, such as helping players attain employment, giving out trophies or watches that players could pawn for money, or paying double in expense money. Despite these extra benefits,
1918-447: A great deal to Harvard's rugby. They decided to play with 15 players on each team. On November 13, 1875, Yale and Harvard played each other for the first time ever, where Harvard won 4–0. At the first The Game (as the annual contest between Harvard and Yale came to be named) the future "father of American football" Walter Camp was among the 2000 spectators in attendance. Walter, a native of New Britain, Connecticut , would enroll at Yale
2055-533: 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 100 years and is considered 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. To try to prevent injuries, players are required to wear
2192-564: A league-suggested numbering scheme. Although the sport is played almost exclusively by men, women are eligible to play in high school, college, and professional football. No woman has ever played in the NFL, but women have played in high school and college football games. In 2018, 1,100 of the 225,000 players in Pop Warner Little Scholars youth football were girls, and around 11% of the 5.5 million Americans who report playing tackle football are female according to
2329-548: A liking to the rugby game, and its use of the try which, until that time, was not used in American football. The try would later evolve into the score known as the touchdown . On June 4, 1875, Harvard faced Tufts University in the first game between two American colleges played under rules similar to the McGill/Harvard contest, which was won by Tufts 1–0. The rules included each side fielding 11 men at any given time,
2466-408: A long circumference of 28 to 28 + 1 ⁄ 2 inches (71 to 72 cm), and a short circumference of 21 to 21 + 1 ⁄ 4 inches (53 to 54 cm). In college and high school play the ball has a long axis of 10 + 7 ⁄ 8 to 11 + 7 ⁄ 16 inches (27.6 to 29.1 cm), a long circumference of 27 + 3 ⁄ 4 to 28 + 1 ⁄ 2 inches (70 to 72 cm), and
2603-420: A minimum of 10 feet (3.0 m) on high school fields. Goal posts are padded at the base, and orange ribbons are normally placed at the tip of each upright as indicators of wind strength and direction. The football itself is a prolate spheroid leather ball, similar to the balls used in rugby or Australian rules football . To contain the compressed air within it, a pig's bladder was commonly used before
2740-704: A national champion of college football. The first was the Bowl Coalition , in place from 1992 to 1994. This was replaced in 1995 by the Bowl Alliance , which gave way to the Bowl Championship Series (BCS) in 1997. The BCS arrangement proved to be controversial , and was replaced in 2014 by the College Football Playoff (CFP). A football game is played between two teams of 11 players each. Playing with more on
2877-501: A new code of rules based on the rugby game first introduced to Harvard by McGill University in 1874. Three of the schools—Harvard, Columbia, and Princeton—formed the Intercollegiate Football Association, as a result of the meeting. Yale initially refused to join this association because of a disagreement over the number of players to be allowed per team (relenting in 1879) and Rutgers were not invited to
SECTION 20
#17327801356103014-428: A pass hits the ground without a player having caught it. A forward pass can be legally attempted only if the passer is behind the line of scrimmage; only one forward pass can be attempted per down. As in rugby, players can also pass the ball backwards at any point during a play. In the NFL, a down also ends immediately if the runner's helmet comes off. The offense is given a series of four plays, known as downs . If
3151-503: A player to pick up the ball and run with it whenever he wished. Another rule, unique to McGill, was to count tries (the act of grounding the football past the opposing team's goal line; there was no end zone during this time), as well as goals, in the scoring. In the Rugby rules of the time, a try only provided the attempt to kick a free goal from the field. If the kick was missed, the try did not score any points itself. Harvard quickly took
3288-416: A professional roster spot as an undrafted free agent . Despite these opportunities, only around 1.6% of NCAA college football players end up playing professionally in the NFL. Even after the emergence of the professional National Football League (NFL), college football has remained extremely popular throughout the U.S. Although the college game has a much larger margin for talent than its pro counterpart,
3425-427: A quarter ends, play continues until the down is completed. If certain fouls are committed during play while time has expired, the quarter may be extended through an untimed down . 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
3562-510: A rougher version of football called "the Boston Game" in which the kicking of a round ball was the most prominent feature though a player could run with the ball, pass it, or dribble it (known as "babying"). The man with the ball could be tackled, although hitting, tripping, "hacking" and other unnecessary roughness was prohibited. There was no limit to the number of players, but there were typically ten to fifteen per side. A player could carry
3699-533: A round ball instead of a rugby-style oblong ball. This series of games represents an important milestone in the development of the modern game of American football. In October 1874, the Harvard team once again traveled to Montreal to play McGill in rugby, where they won by three tries. In as much as Rugby football had been transplanted to Canada from England, the McGill team played under a set of rules which allowed
3836-414: 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, with the objective being to advance it into the opponent's goal. Rutgers won the game 6–4. Collegiate play continued for several years with games played using the rules of the host school. Representatives of Yale, Columbia , Princeton and Rutgers met on October 19, 1873, to create
3973-422: A rule in 1882 that limited each team to three downs , or tackles, to advance the ball 5 yards (4.6 m). Failure to advance the ball the required distance within those three downs would result in control of the ball being forfeited to the other team. This change effectively made American football a separate sport from rugby, and the resulting five-yard lines added to the field to measure distances made it resemble
4110-436: A secondary signal. Women can serve as officials; Sarah Thomas became the NFL's first female official in 2015. The seven officials (of a standard seven-man crew; lower levels of play up to the college level use fewer officials) on the field are each tasked with a different set of responsibilities: Another set of officials, the chain crew , are responsible for moving the chains. The chains, consisting of two large sticks with
4247-595: 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 mouthguards . 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 . College football NAIA : NJCAA : College football ( French : football universitaire )

4384-410: A short circumference of 20 + 3 ⁄ 4 to 21 + 1 ⁄ 4 inches (53 to 54 cm). 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
4521-456: A standard set of rules for use by all schools. Teams were set at 20 players each, and fields of 400 by 250 feet (122 m × 76 m) were specified. Harvard abstained from the conference, as they favored a rugby-style game that allowed running with the ball. After playing McGill University using both American (known as "the Boston game ") for the first game and Canadian (rugby) rules for
4658-537: A team be required to advance the ball a minimum of five yards within three downs. These down-and-distance rules, combined with the establishment of the line of scrimmage, transformed the game from a variation of rugby football into the distinct sport of American football. Camp was central to several more significant rule changes that came to define American football. In 1881, the field was reduced in size to its modern dimensions of 120 by 53 1 ⁄ 3 yards (109.7 by 48.8 meters). Several times in 1883, Camp tinkered with
4795-449: A tradition of postseason bowl games . Each bowl game was associated with a particular conference and earning a spot in a bowl game was the reward for winning a conference. This arrangement was profitable, but it tended to prevent the two top-ranked teams from meeting in a true national championship game, as they would normally be committed to the bowl games of their respective conferences. Several systems have been used since 1992 to determine

Following the introduction of rugby-style rules to American football, Camp became a fixture at the Massasoit House conventions where rules were debated and changed. Dissatisfied with what seemed to him to be a disorganized mob, he proposed his first rule change at

It was through collegiate competition that gridiron football first gained popularity in the United States . Like gridiron football generally, college football is most popular in the United States and Canada. While no single governing body exists for college football in the United States, most schools, especially those at
5206-425: Is called on the offense. There are two main ways the offense can advance the ball: running and passing . In a typical play, the center passes the ball backwards and between their legs to the quarterback in a process known as the snap . The quarterback then either hands the ball off to a running back, throws the ball, or runs with it. The play ends when the player with the ball is tackled or goes out-of-bounds or
5343-437: 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. The receiving team has the option of signaling for a fair catch , which prohibits the defense from blocking into or tackling the receiver. The play ends as soon as

In some parts of the United States, especially the South and Midwest , college football is more popular than professional football. For much of the 20th century, college football was generally considered to be more prestigious than professional football. The overwhelming majority of professional football players in
5617-403: Is known as a two-point conversion . In general, the extra point is almost always successful, 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 place kicked or drop kicked through the uprights and over

5754-407: Is responsible for all kicking plays. The special teams unit of the team in control of the ball tries to execute field goal (FG) attempts, punts , and kickoffs , while the opposing team's unit will aim to block or return them. Three positions are specific to the field goal and PAT (point-after-touchdown) unit: the placekicker (K or PK), holder (H), and long snapper (LS). The long snapper's job
5891-421: Is to block members of the defensive line from tackling the ball carrier on running plays or sacking the quarterback on passing plays. The leader of the offensive line is the center, who is responsible for snapping the ball to the quarterback, blocking, and for making sure that the other linemen do their jobs during the play. On either side of the center are the guards (G), while tackles (T) line up outside
6028-437: Is to snap the football to the holder, who will catch and position it for the placekicker. There is not usually a holder on kickoffs, because the ball is kicked off a tee; however, a holder may be used in certain situations, such as if wind is preventing the ball from remaining upright on the tee. The player on the receiving team who catches the ball is known as the kickoff returner (KR). The positions specific to punt plays are

The game, a 23–17 overtime victory by the Colts, was seen by millions of television viewers and had a major influence on the popularity of the sport. This, along with the innovations introduced by the new American Football League (AFL) in the early 1960s, helped football to become

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
6987-407: The punter (P), long snapper, upback , and gunner . The long snapper snaps the football directly to the punter, who then drops and kicks it before it hits the ground. Gunners line up split outside the line and race down the field, aiming to tackle the punt returner (PR)—the player who catches the punt. Upbacks line up a short distance behind the line of scrimmage, providing additional protection to

While the game between Rutgers and Princeton is commonly considered the first American football game, several years prior in 1862, the Oneida Football Club formed as the oldest known football club in
7261-464: The "Father of American Football", established the snap , the line of scrimmage , eleven-player teams, and the concept of downs. Later rule changes legalized the forward pass , created the neutral zone , and specified the size and shape of the football. The sport is closely related to Canadian football , which evolved in parallel with and at the same time as the American game, although its rules were developed independently from those of Camp. Most of

Before 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 could now hold the ball indefinitely to prevent their opponent from scoring. In 1881, in

Halfbacks may also serve as receivers. Fullbacks tend to be larger than halfbacks and function primarily as blockers, but they are sometimes used as runners in short-yardage or goal-line situations. They are seldom used as receivers. The offensive line (OL) consists of several players whose primary function

Rugby league followed Camp's example, and in 1906 introduced the play-the-ball rule, which greatly resembled Camp's early scrimmage and center-snap rules. In 1966, rugby league introduced a four-tackle rule (changed in 1972 to a six-tackle rule) based on Camp's early down-and-distance rules. Camp's new scrimmage rules revolutionized
10138-563: The city of New Haven , banned the play of all forms of football in 1860. American football historian Parke H. Davis described the period between 1869 and 1875 as the 'Pioneer Period'; the years 1876–93 he called the 'Period of the American Intercollegiate Football Association'; and the years 1894–1933 he dubbed the "Period of Rules Committees and Conferences". On November 6, 1869, Rutgers University faced Princeton University , then known as
10275-489: The college authorities agreed the Bloody Monday had to go. Harvard students responded by going into mourning for a mock figure called "Football Fightum", for whom they conducted funeral rites. The authorities held firm, and it was another dozen years before football was once again played at Harvard. Dartmouth played its own version called " Old division football ", the rules of which were first published in 1871, though
10412-413: The crossbars of the defense's goalposts. In practice, almost all field goal attempts are done via place kick. While drop kicks were common in the early days of the sport, the shape of modern footballs makes it difficult to reliably drop kick the ball. The last successful scoring play by drop kick in the NFL was accomplished in 2006; prior to that, the last successful drop kick had been made in 1941. After
10549-399: The defense is to prevent the offense from scoring by tackling the ball carrier or by forcing turnovers . Turnovers include interceptions (a defender catching a forward pass intended for the offense) and forced fumbles (taking possession of the ball from the ball-carrier). The defensive line (DL) consists of defensive ends (DE) and defensive tackles (DT). Defensive ends line up on
10686-430: The defensive backfield. They are divided into two types: middle linebackers (MLB) and outside linebackers (OLB). Linebackers tend to serve as the defensive leaders and call the defensive plays, given their vantage point of the offensive backfield. Their roles include defending the run, pressuring the quarterback, and tackling backs, wide receivers, and tight ends in the passing game. The defensive backfield , often called
10823-472: The ends and sides of the field are known as the end lines and sidelines . Goal lines are marked 10 yards (9.1 m) inward from each end line. Weighted pylons are placed the sidelines on the inside corner of the intersections with 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 can run
10960-404: The ends of the line, while defensive tackles line up inside, between the defensive ends. The primary responsibilities of defensive ends and defensive tackles are to stop running plays on the outside and inside, respectively, to pressure the quarterback on passing plays, and to occupy the line so that the linebackers can break through. Linebackers line up behind the defensive line but in front of
11097-561: The features that distinguish American football from rugby and soccer are also present in Canadian football. The two sports are considered the primary variants of gridiron football . American football is the most popular sport in the United States in terms of broadcast viewership audience. The most popular forms of the game are professional and college football , with the other major levels being high-school and youth football. As of 2022 , nearly 1.04 million high-school athletes play
11234-468: The field is punishable by a penalty. Teams may substitute any number of their players between downs; this "platoon" system replaced the original system, which featured limited substitution rules, and has resulted in teams utilizing specialized offensive, defensive and special teams units. The number of players allowed on an active roster varies by league; the NFL has a 53-man roster, while NCAA Division I allows teams to have 63 scholarship players in
11371-454: The field was shortened to 100 yards (91 m) long, two 10-yard-long (9.1 m) end zones were created, and teams were given four downs instead of three to advance the ball 10 yards (9.1 m). The roughing the passer penalty was implemented in 1914, and eligible players were first allowed to catch the ball anywhere on the field in 1918. On November 12, 1892, Pudge Heffelfinger was paid $ 500 (equivalent to $ 16,956 in 2023) to play
11508-649: The first game in Virginia. On April 9, 1880, at Stoll Field , Transylvania University (then called Kentucky University) beat Centre College by the score of 13 + 3 ⁄ 4 –0 in what is often considered the first recorded game played in the South . The first game of "scientific football" in the South was the first instance of the Victory Bell rivalry between North Carolina and Duke (then known as Trinity College) held on Thanksgiving Day , 1888, at
11645-404: The first meeting he attended in 1878: a reduction from fifteen players to eleven. The motion was rejected at that time but passed in 1880. The effect was to open up the game and emphasize speed over strength. Camp's most famous change, the establishment of the line of scrimmage and the snap from center to quarterback , was also passed in 1880. Originally, the snap was executed with the foot of
11782-404: The first time. The Yale team was coached and captained by David Schley Schaff, who had learned to play football while attending Rugby School . Schaff himself was injured and unable to play the game, but Yale won the game 3–0 nonetheless. Later in 1872, Stevens Tech became the fifth school to field a team. Stevens lost to Columbia, but beat both New York University and City College of New York during
11919-454: The following year. By 1873, the college students playing football had made significant efforts to standardize their fledgling game. Teams had been scaled down from 25 players to 20. The only way to score was still to bat or kick the ball through the opposing team's goal, and the game was played in two 45-minute halves on fields 140 yards long and 70 yards wide. On October 20, 1873, representatives from Yale, Columbia, Princeton, and Rutgers met at
12056-629: The formation of the Intercollegiate Athletic Association of the United States, later renamed the National Collegiate Athletic Association (NCAA). The legal forward pass was introduced in 1906, although its effect was initially minimal due to the restrictions placed on its use. The idea of a 40-yard-wider field was opposed by Harvard due to the size of the new Harvard Stadium . Other rule changes introduced that year included
12193-419: The game clock based on the direction of the appropriate official . A separate play clock is used to show the amount of time within which the offense must initiate a play. The play clock is set to 25 seconds after certain administrative stoppages in play and to 40 seconds when play is proceeding without such stoppages. If the offense fails to start a play before the play clock reads "00", a delay of game foul
12330-431: The game dates to at least the 1830s. All of these games, and others, shared certain commonalities. They remained largely "mob" style games, with huge numbers of players attempting to advance the ball into a goal area, often by any means necessary. Rules were simple, and violence and injury were common. The violence of these mob-style games led to widespread protests and a decision to abandon them. Yale , under pressure from
12467-409: The game had a strict sense of amateurism at the time, and direct payment to players was frowned upon, if not prohibited outright. Over time, professional play became increasingly common, and with it came rising salaries and unpredictable player movement, as well as the illegal payment of college players who were still in school. The National Football League (NFL), a group of professional teams that
12604-404: The game, though not always as intended. Princeton, in particular, used scrimmage play to slow the game, making incremental progress towards the end zone during each down . Rather than increase scoring, which had been Camp's original intent, the rule was exploited to maintain control of the ball for the entire game, resulting in slow, unexciting contests. At the 1882 rules meeting, Camp proposed that
12741-443: The ground or a tee; 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. 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
12878-434: The guards. The principal receivers are the wide receivers (WR) and the tight ends (TE). Wide receivers line up on or near the line of scrimmage, split outside the line. The main goal of the wide receiver is to catch passes thrown by the quarterback, but they may also function as decoys or as blockers during running plays. Tight ends line up outside the tackles and function both as receivers and as blockers. The role of
13015-636: The highest levels of play, are members of the NCAA . In Canada, collegiate football competition is governed by U Sports for universities. The Canadian Collegiate Athletic Association (for colleges) governs soccer and other sports but not gridiron football. Other countries, such as Mexico , Japan and South Korea , also host college football leagues with modest levels of support. Unlike most other major sports in North America , no official minor league farm organizations exist for American football or Canadian football . Therefore, college football
13152-472: The last two decades of the 19th century. Several major rivalries date from this time period. November 1890 was an active time in the sport. In Baldwin City, Kansas , on November 22, 1890, college football was first played in the state of Kansas . Baker beat Kansas 22–9. On the 27th, Vanderbilt played Nashville (Peabody) at Athletic Park and won 40–0. It was the first time organized football played in
13289-498: The meeting made it hard for them to schedule games against other American universities, it agreed to a challenge to play the rugby team of McGill University , from Montreal , in a two-game series. It was agreed that two games would be played on Harvard's Jarvis baseball field in Cambridge, Massachusetts on May 14 and 15, 1874: one to be played under Harvard rules, another under the stricter rugby regulations of McGill. Jarvis Field
13426-415: The meeting. The rules that they agreed upon were essentially those of rugby union at the time with the exception that points be awarded for scoring a try , not just the conversion afterwards ( extra point ). Incidentally, rugby was to make a similar change to its scoring system 10 years later. Walter Camp is widely considered to be the most important figure in the development of American football. As
13563-452: The mid-19th century. By the 1840s, students at Rugby School were playing a game in which players were able to pick up the ball and run with it, a sport later known as rugby football . The game was taken to Canada by British soldiers stationed there and was soon being played at Canadian colleges. The first documented gridiron football game was played at University College , a college of the University of Toronto , on November 9, 1861. One of
13700-506: The most popular sport in the United States by the mid-1960s. The rival AFL arose in 1960 and challenged the NFL's dominance. The AFL began in relative obscurity but eventually thrived, with an initial television contract with the ABC television network. The AFL's existence forced the conservative NFL to expand to Dallas and Minnesota in an attempt to destroy the new league. Meanwhile, the AFL introduced many new features to professional football in
13837-730: The nearest college to play football. It took place at Hamilton Park in New Haven and was the first game in New England. The game was essentially soccer with 20-man sides, played on a field 400 by 250 feet. Yale wins 3–0, Tommy Sherman scoring the first goal and Lew Irwin the other two. After the first game against Harvard, Tufts took its squad to Bates College in Lewiston, Maine for the first football game played in Maine . This occurred on November 6, 1875. Penn 's Athletic Association
13974-620: The next year. He was torn between an admiration for Harvard's style of play and the misery of the Yale defeat, and became determined to avenge Yale's defeat. Spectators from Princeton also carried the game back home, where it quickly became the most popular version of football. On November 23, 1876, representatives from Harvard, Yale, Princeton, and Columbia met at the Massasoit House hotel in Springfield, Massachusetts to standardize
14111-429: 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 farther down the field; if they are in field goal range , they might attempt to score
14248-410: The offense's advance and to take control of the ball for themselves. The offense must advance the ball at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive . Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking
14385-429: The offensive line. Players can line up temporarily in a position whose eligibility is different from what their number permits as long as they report the change immediately to the referee, who then informs the defensive team of the change. Neither team's players, except the center (C), are allowed to line up in or cross the neutral zone until the ball is snapped. Interior offensive linemen are not allowed to move until
14522-478: The participants in the game involving University of Toronto students was William Mulock , later chancellor of the school. A football club was formed at the university soon afterward, although its rules of play then are unclear. In 1864, at Trinity College , also a college of the University of Toronto, F. Barlow Cumberland and Frederick A. Bethune devised rules based on rugby football. Modern Canadian football
14659-445: The plane of the two end lines. The crossbar of these posts is 10 feet (3.0 m) above the ground, with vertical uprights at the end of the crossbar 18 feet 6 inches (5.64 m) apart for professional and collegiate play, and 23 feet 4 inches (7.11 m) apart for high school play. The uprights extend vertically 35 feet (11 m) on professional fields, a minimum of 10 yards (9.1 m) on college fields, and
14796-451: The point(s)-after-touchdown (PAT) or conversion, which is a single scoring opportunity. This is generally attempted from the two- or three-yard line, depending on the level of play. If the PAT is scored by a place kick or drop kick through the goal posts, it is worth one point, typically called the extra point. If the PAT is scored by what would normally be a touchdown, it is worth two points; this
14933-422: The punter. In football, the winner is the team that has scored more 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, or recovered in the opposing team's end zone. The scoring team then attempts a try, more commonly known as
15070-401: 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
15207-439: The reduction of playing time from 70 to 60 minutes and an increase of the distance required for a first down from 5 to 10 yards (4.6 to 9.1 m). To reduce infighting and dirty play between teams, the neutral zone was created along the width of the football before the snap. Scoring was also adjusted: points awarded for field goals were reduced to three in 1909 and points for touchdowns were raised to six in 1912. Also in 1912,
15344-542: The rulebook for the 1876 college football season , when the sport first shifted from soccer-style rules to rugby-style rules. Although it could easily have been called "rugby" at this point, Harvard, one of the primary proponents of the rugby-style game, compromised and did not request the name of the sport be changed to "rugby". The terms " gridiron " or "American football" are favored in English-speaking countries where other types of football are popular, such as
15481-489: The rules of their various public schools. The game was played at a Rutgers Field in New Brunswick, New Jersey . Two teams of 25 players attempted to score by kicking the ball into the opposing team's goal. Throwing or carrying the ball was not allowed, but there was plenty of physical contact between players. The first team to reach six goals was declared the winner. Rutgers won by a score of six to four. A rematch
15618-625: The rules were changed to allow tackling below the waist, and in 1889, the officials were given whistles and stopwatches. After leaving Yale in 1882, Camp was employed by the New Haven Clock Company until his death in 1925. Though no longer a player, he remained a fixture at annual rules meetings for most of his life, and he personally selected an annual All-American team every year from 1889 through 1924. The Walter Camp Football Foundation continues to select All-American teams in his honor. College football expanded greatly during
15755-591: The score of this contest. Washington and Lee also claims a 4 to 2 win over VMI in 1873. On October 18, 1888, the Wake Forest Demon Deacons defeated the North Carolina Tar Heels 6 to 4 in the first intercollegiate game in the state of North Carolina . On December 14, 1889, Wofford defeated Furman 5 to 1 in the first intercollegiate game in the state of South Carolina . The game featured no uniforms, no positions, and
15892-431: The scoring rules, finally arriving at four points for a touchdown, two points for kicks after touchdowns , two points for safeties, and five for field goals . Camp's innovations in the area of point scoring influenced rugby union's move to point scoring in 1890. In 1887, game time was set at two-halves of 45 minutes each. Also in 1887, two paid officials—a referee and an umpire —were mandated for each game. A year later,
16029-402: The second one, the Harvard players preferred the Canadian style of having only 11 men on the field, running the ball without having to be chased by an opponent, the forward pass, tackling, and using an oblong instead of a round ball. An 1875 Harvard–Yale game played under rugby-style rules was observed by two Princeton athletes who were impressed by it. They introduced the sport to Princeton,
16166-503: The secondary, consists of cornerbacks (CB) and safeties (S). Safeties are themselves divided into free safeties (FS) and strong safeties (SS). Cornerbacks line up outside the defensive formation, typically opposite a receiver to be able to cover them. Safeties line up between the cornerbacks but farther back in the secondary. Safeties tend to be viewed as "the last line of defense" and are responsible for stopping deep passing plays as well as breakout running plays. The special teams unit
16303-427: The sheer number of fans following major colleges provides a financial equalizer for the game, with Division I programs – the highest level – playing in huge stadiums, six of which have seating capacity exceeding 100,000 people. In many cases, college stadiums employ bench-style seating, as opposed to individual seats with backs and arm rests (although many stadiums do have a small number of chair back seats in addition to
16440-411: The snap of the ball. The main backfield positions are the quarterback (QB), halfback/tailback (HB/TB), and fullback (FB). The quarterback is the leader of the offense. Either the quarterback or a coach calls the plays. Quarterbacks typically inform the rest of the offense of the play in the huddle before the team lines up. The quarterback lines up behind the center to take the snap and then hands
16577-481: The sport in the U.S., with another 81,000 college athletes in the NCAA and the NAIA . The National Football League (NFL) has the highest average attendance of any professional sports league in the world . Its championship game, the Super Bowl , ranks among the most-watched club sporting events globally. In 2022, the league had an annual revenue of around $ 18.6 billion, making it the most valuable sports league in
16714-487: The state of Tennessee . The 29th also saw the first instance of the Army–Navy Game . Navy won 24–0. Rutgers was first to extend the reach of the game. An intercollegiate game was first played in the state of New York when Rutgers played Columbia on November 2, 1872. It was also the first scoreless tie in the history of the fledgling sport. Yale football starts the same year and has its first match against Columbia,
16851-499: The time was played at the collegiate level . The upstart NFL received a boost to its legitimacy in 1925, however, when an NFL team, the Pottsville Maroons , defeated a team of Notre Dame all-stars in an exhibition game . A greater emphasis on the passing game helped professional football to distinguish itself further from the college game during the late 1930s. Football, in general, became increasingly popular following
16988-466: The two schools organized a game for October 23, 1869, but it was rained out. Students of the University of Virginia were playing pickup games of the kicking-style of football as early as 1870, and some accounts even claim it organized a game against Washington and Lee College in 1871; but no record has been found of the score of this contest. Due to scantiness of records of the prior matches some will claim Virginia v. Pantops Academy November 13, 1887, as
17125-411: The width of the field, are marked every 5 yards (4.6 m). A one-yard-wide line 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 yards are placed on both sides of the field every ten yards. Goalposts are located at the center of
17262-408: The winning team decides to defer, the losing team chooses the option the winning team did not select—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 allows 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
17399-402: The world. Other professional and amateur leagues exist worldwide, but the sport does not have the international popularity of other American sports like baseball or basketball ; the sport maintains a growing following in the rest of North America, Europe, Brazil, and Japan. In the United States, American football is referred to as "football". The term "football" was officially established in
17536-473: Was also the first time one team scored over 100 points and the opposing team was shut out. The next week, Princeton outscored Lafayette 140 to 0. The first intercollegiate game in the state of Vermont happened on November 6, 1886, between Dartmouth and Vermont at Burlington, Vermont . Dartmouth won 91 to 0. Penn State played its first season in 1887, but had no head coach for their first five years, from 1887 to 1891. The teams played its home games on
17673-512: Was at the time a patch of land at the northern point of the Harvard campus, bordered by Everett and Jarvis Streets to the north and south, and Oxford Street and Massachusetts Avenue to the east and west. Harvard beat McGill in the "Boston Game" on the Thursday and held McGill to a 0–0 tie on the Friday. The Harvard students took to the rugby rules and adopted them as their own, The games featured
17810-538: Was felt they would dominate the Association. Penn State won the championship with a 4–1–0 record. Bucknell's record was 3–1–1 (losing to Franklin & Marshall and tying Dickinson). The Association was dissolved prior to the 1892 season. The first nighttime football game was played in Mansfield, Pennsylvania on September 28, 1892, between Mansfield State Normal and Wyoming Seminary and ended at halftime in
17947-457: Was instituted. Despite these new rules, football remained a violent sport. Dangerous mass-formations like the flying wedge resulted in serious injuries and deaths. A 1905 peak of 19 fatalities nationwide resulted in a threat by President Theodore Roosevelt to abolish the game unless major changes were made. In response, 62 colleges and universities met in New York City to discuss rule changes on December 28, 1905. These proceedings resulted in
18084-562: Was looking to pick "a twenty" to play a game of football against Columbia. This "twenty" never played Columbia, but did play twice against Princeton. Princeton won both games 6 to 0. The first of these happened on November 11, 1876, in Philadelphia and was the first intercollegiate game in the state of Pennsylvania . Brown entered the intercollegiate game in 1878. The first game where one team scored over 100 points happened on October 25, 1884, when Yale routed Dartmouth 113–0. It
18221-535: Was originally established in 1920 as the American Professional Football Association, aimed to solve these problems. This new league's stated goals included an end to bidding wars over players, prevention of the use of college players, and abolition of the practice of paying players to leave another team. By 1922, the NFL had established itself as America's premier professional football league. The dominant form of football at
18358-542: Was played at Princeton a week later under Princeton's own set of rules (one notable difference was the awarding of a "free kick" to any player that caught the ball on the fly, which was a feature adopted from The Football Association's rules; the fair catch kick rule has survived through to modern American game). Princeton won that game by a score of 8 – 0. Columbia joined the series in 1870 and by 1872 several schools were fielding intercollegiate teams, including Yale and Stevens Institute of Technology . Columbia University
18495-617: Was the 1881 Michigan team , which played at Harvard, Yale and Princeton. The nation's first college football league, the Intercollegiate Conference of Faculty Representatives (also known as the Western Conference), a precursor to the Big Ten Conference , was founded in 1895. Led by coach Fielding H. Yost , Michigan became the first "western" national power. From 1901 to 1905, Michigan had
18632-656: Was the first game west of the Mississippi River . November 30, 1905, saw Chicago defeat Michigan 2 to 0. Dubbed "The First Greatest Game of the Century", it broke Michigan's 56-game unbeaten streak and marked the end of the "Point-a-Minute" years. Organized collegiate football was first played in the state of Virginia and the south on November 2, 1873, in Lexington between Washington and Lee and VMI . Washington and Lee won 4–2. Some industrious students of
18769-488: Was the third school to field a team. The Lions traveled from New York City to New Brunswick on November 12, 1870, and were defeated by Rutgers 6 to 3. The game suffered from disorganization and the players kicked and battled each other as much as the ball. Later in 1870, Princeton and Rutgers played again with Princeton defeating Rutgers 6–0. This game's violence caused such an outcry that no games at all were played in 1871. Football came back in 1872, when Columbia played Yale for
