The history of American football can be traced to early versions of rugby football and association football. Both games have their origin in varieties of football played in Britain in the mid-19th century, in which a football is kicked at a goal and/or run over a line.
American football resulted from several major divergences from rugby, most notably the rule changes instituted by Walter Camp, considered the "Father of American Football". Among these important changes were the introduction of the line of scrimmage and of down-and-distance rules. In the late 19th and early 20th centuries, gameplay developments by college coaches such as Eddie Cochems, Amos Alonzo Stagg, Knute Rockne, and Glenn "Pop" Warner helped take advantage of the newly introduced forward pass. The popularity of collegiate football grew as it became the dominant version of the sport in the United States for the first half of the 20th century. Bowl games, a college football tradition, attracted a national audience for collegiate teams. Bolstered by fierce rivalries, college football still holds widespread appeal in the US.
Tntions where rules were debated and changed. He proposed his first rule change at 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 the center. Later changes made it possible to snap the ball with the hands, either through the air or by a direct hand-to-hand pass.
Camp's new scrimmage rules revolutionized 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 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 scrimma
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 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. 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, 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 the last two decades of the 19th century. In 1880, only eight universities fielded intercollegiate teams, but by 1900, the number had expanded to 43. Several major rivalries date from this time period.
In 1879, the University of Michigan became the first school west of Pennsylvania to establish a college football team. 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 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.
The first ever nighttime football game was played in Mansfield, Pennsylvania on September 28, 1892 between Mansfield State Normal and Wyoming Seminary and ended at halftime in a 0–0 tie.
Led by legendary coach Fielding H. Yost, Michigan became the first "western" national power. From 1901 to 1905, Michigan had a 56-game undefeated streak that included a 1902 trip to play in the first college football post-season game, the Rose Bowl. During this streak, Michigan scored 2,831 points while allowing only 40.

Violence and controversy (1905)
From its earliest days as a mob game, football was a violent sport. The 1894 Harvard-Yale game, known as the "Hampden Park Blood Bath", resulted in crippling injuries for four players; the contest was suspended until 1897. The annual Army-Navy game was suspended from 1894–1898 for similar reasons. One of the major problems was the popularity of mass-formations like the flying wedge, in which a large number of offensive players charged as a unit against a similarly arranged defense. The resultant collisions often led to serious injuries and sometimes even death.
The situation came to a head in 1905 when there were 19 fatalities nationwide. President Theodore Roosevelt threatened to shut down the game if drastic changes were not made. John H. Outland held an experimental game in Wichita, Kansas that reduced the number of scrimmage plays to earn a first down from four to three in an attempt to reduce injuries. The Los Angeles Times reported an increase in punts and considered the game much safer than regular play but that the new rule was not "conducive to the sport."
On December 28, 1905, 62 schools met in New York City to discuss rule changes to make the game safer. As a result of this meeting, the Intercollegiate Athletic Association of the United States, later named the National Collegiate Athletic Association (NCAA), was formed. One rule change introduced in 1906, devised to open up the game and reduce injury, was the introduction of the legal forward pass. Though it was underutilized for years, this proved to be one of the most important rule changes in the establishment of the modern game.
Modernization and innovation (1906–1930)
As a result of the 1905–1906 reforms, mass formation plays became illegal and forward passes legal. Bradbury Robinson, playing for visionary coach Eddie Cochems at St. Louis University, threw the first legal pass in a September 5, 1906 game against Carroll College at Waukesha. Other important changes, formally adopted in 1910, were the requirements that at least seven offensive players be on the line of scrimmage at the time of the snap, that there be no pushing or pulling, and that interlocking interference (arms linked or hands on belts and uniforms) was not allowed. These changes greatly reduced the potential for collision injuries. Several coaches emerged who took advantage of these sweeping changes. Amos Alonzo Stagg introduced such innovations as the huddle, the tackling dummy, and the pre-snap shift. Other coaches, such as Pop Warner and Knute Rockne, introduced new strategies that still remain part of the game.
Besides these coaching innovations, several rules changes during the first third of the 20th century had a profound impact on the game, mostly in opening up the passing game. In 1914, the first roughing-the-passer penalty was implemented. In 1918, the rules on eligible receivers were loosened to allow eligible players to catch the ball anywhere on the field—previously strict rules were in place only allowing passes to certain areas of the field. Scoring rules also changed during this time: field goals were lowered to three points in 1909 and touchdowns raised to six points in 1912.
Star players that emerged in the early 20th century include Jim Thorpe, Red Grange, and Bronko Nagurski; these three made the transition to the fledgling NFL and helped turn it into a successful league. Sportswriter Grantland Rice helped popularize the sport with his poetic descriptions of games and colorful nicknames for the game's biggest players, including Grange, whom he dubbed "The Galloping Ghost," Notre Dame's "Four Horsemen" backfield, and Fordham University's linemen, known as the "Seven Blocks of Granite".
Glenn "Pop" Warner
Glenn "Pop" Warner coached at several schools throughout his career, including the University of Georgia, Cornell University, University of Pittsburgh, Stanford University, and Temple University. One of his most famous stints was at the Carlisle Indian Industrial School, where he coached Jim Thorpe, who went on to become the first president of the National Football League, an Olympic Gold Medalist, and is widely considered one of the best overall athletes in history. Warner wrote one of the first important books of football strategy, Football for Coaches and Players, published in 1927. Though the shift was invented by Stagg, Warner's single wing and double wing formations greatly improved upon it; for almost 40 years, these were among the most important formations in football. As part of his single and double wing formations, Warner was one of the first coaches to effectively utilize the forward pass. Among his other innovations are modern blocking schemes, the three-point stance, and the reverse play. The youth football league, Pop Warner Little Scholars, was named in his honor.
Knute Rockne rose to prominence in 1913 as an end for the University of Notre Dame, then a largely unknown Midwestern Catholic school. When Army scheduled Notre Dame as a warm-up game, they thought little of the small school. Rockne and quarterback Gus Dorais made innovative use of the forward pass, still at that point a relatively unused weapon, to defeat Army 35–13 and helped establish the school as a national power. Rockne returned to coach the team in 1918, and devised the powerful Notre Dame Box offense, based on Warner's single wing. He is credited with being the first major coach to emphasize offense over defense. Rockne is also credited with popularizing and perfecting the forward pass, a seldom used play at the time. In 1927, his complex shifts led directly to a rule change whereby all offensive players had to stop for a full second before the ball could be snapped. Rather than simply a regional team, Rockne's "Fighting Irish" became famous for barnstorming and played any team at any location. It was during Rockne's tenure that the annual Notre Dame-University of Southern California rivalry began. He led his team to an impressive 105–12–5 record before his premature death in a plane crash in 1931. He was so famous at that point that his funeral was broadcast nationally on radio.
From a regional to a national sport (1930–1958)
In the early 1930s, the college game continued to grow, particularly in the South, bolstered by fierce rivalries such as the "South's Oldest Rivalry", between Virginia and North Carolina and the "Deep South's Oldest Rivalry", between Georgia and Auburn. Although before the mid-1920s most national powers came from the Northeast or the Midwest, the trend changed when several teams from the South and the West Coast achieved national success. Wallace William Wade's 1925 Alabama team won the 1926 Rose Bowl after receiving its first national title and William Alexander's 1928 Georgia Tech team defeated California in the 1929 Rose Bowl. College football quickly became the most popular spectator sport in the South.
Several major modern college football conferences rose to prominence during this time period. The Southwest Athletic Conference had been founded in 1915. Consisting mostly of schools from Texas, the conference saw back-to-back national champions with Texas Christian University (TCU) in 1938 and Texas A&M in 1939. The Pacific Coast Conference (PCC), a precursor to the Pacific-12 Conference (Pac-12), had its own back-to-back champion in the University of Southern California which was awarded the title in 1931 and 1932. The Southeastern Conference (SEC) formed in 1932 and consisted mostly of schools in the Deep South. As in previous decades, the Big Ten continued to dominate in the 1930s and 1940s, with Minnesota winning 5 titles between 1934 and 1941, and Michigan (1933 and 1948) and Ohio State (1942) also winning titles.
As it grew beyond its regional affiliations in the 1930s, college football garnered increased national attention. Four new bowl games were created: the Orange Bowl, Sugar Bowl, the Sun Bowl in 1935, and the Cotton Bowl in 1937. In lieu of an actual national championship, these bowl games, along with the earlier Rose Bowl, provided a way to match up teams from distant regions of the country that did not otherwise play. In 1936, the Associated Press began its weekly poll of prominent sports writers, ranking all of the nation's college football teams. Since there was no national championship game, the final version of the AP poll was used to determined who was crowned the National Champion of college football.
The 1930s saw growth in the passing game. Though some coaches, such as General Robert Neyland at Tennessee, continued to eschew its use, several rules changes to the game had a profound effect on teams' ability to throw the ball. In 1934, the rules committee removed two major penalties—a loss of five yards for a second incomplete pass in any series of downs and a loss of possession for an incomplete pass in the end zone—and shrunk the circumference of the ball, making it easier to grip and throw. Players who became famous for taking advantage of the easier passing game included Alabama receiver Don Hutson and TCU passer "Slingin" Sammy Baugh.
In 1935, New York City's Downtown Athletic Club awarded the first Heisman Trophy to University of Chicago halfback Jay Berwanger, who was also the first ever NFL Draft pick in 1936. The trophy was designed by sculptor Frank Eliscu and modeled after NYU player Ed Smith. The trophy recognizes the nation's "most outstanding" college football player and has become one of the most coveted awards in all of American sports.
During World War II, college football players enlisted in the armed forces. As most of these players had eligibility left on their college careers, some of them returned to college at West Point, bringing Army back-to-back national titles in 1944 and 1945 under coach Red Blaik. Doc Blanchard (known as "Mr. Inside") and Glenn Davis (known as "Mr. Outside") both won the Heisman Trophy, in 1945 and 1946 respectively. On the coaching staff of those 1944–1946 Army teams was future Pro Football Hall of Fame coach Vince Lombardi.
The 1950s saw the rise of yet more dynasties and power programs. Oklahoma, under coach Bud Wilkinson, won three national titles (1950, 1955, 1956) and all ten Big Eight Conference championships in the decade while building a record 47 game winning streak. Woody Hayes led Ohio State to two national titles, in 1954 and 1957, and dominated the Big Ten conference, winning three Big Ten titles—more than any other school. Wilkinson and Hayes, along with Robert Neyland of Tennessee, oversaw a revival of the running game in the 1950s. Passing numbers dropped from an average of 18.9 attempts in 1951 to 13.6 attempts in 1955, while teams averaged just shy of 50 running plays per game. Nine out of ten Heisman trophy winners in the 1950s were runners. Notre Dame, one of the biggest passing teams of the decade, saw a substantial decline in success; the 1950s were the only decade between 1920 and 1990 when the team did not win at least a share of the national title. Paul Hornung, Notre Dame quarterback, did however win the Heisman in 1956, becoming the only player from a losing team ever to do so.
Modern college football (1950–present)
Following the enormous television success of the National Football League's 1958 championship game, college football no longer enjoyed the same popularity as the NFL, at least on a national level. While both games benefited from the advent of television, since the late 1950s, the NFL has become a nationally popular sport while college football has maintained strong regional ties.
As professional football became a national television phenomenon, college football did as well. In the 1950s, Notre Dame, which had a large national following, formed its own network to broadcast its games, but by and large the sport still retained a mostly regional following. In 1952, the NCAA claimed all television broadcasting rights for the games of its member institutions, and it alone negotiated television rights. This situation continued until 1984, when several schools brought a suit under the Sherman Antitrust Act; the Supreme Court ruled against the NCAA and schools are now free to negotiate their own television deals. ABC Sports began broadcasting a national Game of the Week in 1966, bringing key matchups and rivalries to a national audience for the first time.
New formations and play sets continued to be developed. Emory Bellard, an assistant coach under Darrell Royal at the University of Texas, developed a three-back option style offense known as the wishbone. The wishbone is a run-heavy offense that depends on the quarterback making last second decisions on when and to whom to hand or pitch the ball to. Royal went on to teach the offense to other coaches, including Bear Bryant at Alabama, Chuck Fairbanks at Oklahoma and Pepper Rodgers at UCLA; who all adapted and developed it to their own tastes. The strategic opposite of the wishbone is the spread offense, developed by professional and college coaches throughout the 1960s and 1970s. Though some schools play a run-based version of the spread, its most common use is as a passing offense designed to "spread" the field both horizontally and vertically. Some teams have managed to adapt with the times to keep winning consistently. In the rankings of the most victorious programs, Michigan, Texas, and Notre Dame are ranked 1, 2, and 3 as judged by both total wins and winning percentage.
Growth of bowl games
|Growth of bowl |
|Year||# of games|
In 1940, for the highest level of college football, there were only five bowl games (Rose, Orange, Sugar, Sun, and Cotton). By 1950, three more had joined that number and in 1970, there were still only eight major college bowl games. The number grew to eleven in 1976. At the birth of cable television and cable sports networks like ESPN, there were fifteen bowls in 1980. With more national venues and increased available revenue, the bowls saw an explosive growth throughout the 1980s and 1990s. In the thirty years from 1950 to 1980, seven bowl games were added to the schedule. From 1980 to 2008, an additional 20 bowl games were added to the schedule. Some have criticized this growth, claiming that the increased number of games has diluted the significance of playing in a bowl game. Yet others have countered that the increased number of games has increased exposure and revenue for a greater number of schools, and see it as a positive development.
With the growth of bowl games, it became difficult to determine a national champion in a fair and equitable manner. As conferences became contractually bound to certain bowl games (a situation known as a tie-in), match-ups that guaranteed a consensus national champion became increasingly rare. In 1992, seven conferences and independent Notre Dame formed the Bowl Coalition, which attempted to arrange an annual No.1 versus No.2 matchup based on the final AP poll standings. The Coalition lasted for three years, however several scheduling issues prevented much success; tie-ins still took precedence in several cases. For example the Big Eight and SEC champions could never meet, since they were contractually bound to different bowl games. The coalition also excluded the Rose Bowl, arguably the most prestigious game in the nation, and two major conferences—the Pac-10 and Big Ten—meaning that it had limited success. In 1995, the Coalition was replaced by the Bowl Alliance, which reduced the number of bowl games to host a national championship game to three—the Fiesta, Sugar, and Orange Bowls—and the participating conferences to five—the ACC, SEC, Southwest, Big Eight, and Big East. It was agreed that the No.1 and No.2 ranked teams gave up their prior bowl tie-ins and were guaranteed to meet in the national championship game, which rotated between the three participating bowls. The system still did not include the Big Ten, Pac-10, or the Rose Bowl, and thus still lacked the legitimacy of a true national championship.
Bowl Championship Series
In 1998, a new system was put into place, the Bowl Championship Series. For the first time, it included all major conferences (ACC, Big East, Big 12, Big Ten, Pac-10, and SEC) and all four major bowl games (Rose, Orange, Sugar and Fiesta). The champions of these six conferences, along with two "at-large" selections, were invited to play in the four bowl games. Each year, one of the four bowl games served as a national championship game. Also, a complex system of human polls, computer rankings, and strength of schedule calculations was instituted to rank schools. Based on this ranking system, the No.1 and No.2 teams met each year in the national championship game. Traditional tie-ins were maintained for schools and bowls not part of the national championship. For example, in years when not a part of the national championship, the Rose Bowl still hosted the Big Ten and Pac-10 champions.
The system continued to change, as the formula for ranking teams was tweaked from year to year. At-large teams could be chosen from any of the Division I conferences, though only one selection—Utah in 2005—came from a non-BCS affiliated conference. Starting with the 2006 season, a fifth game—simply called the BCS National Championship Game—was added to the schedule, to be played at the site of one of the four BCS bowl games on a rotating basis, one week after the regular bowl game. This opened up the BCS to two additional at-large teams. Also, rules were changed to add the champions of five additional conferences (Conference USA, the Mid-American Conference, the Mountain West Conference, the Sun Belt Conference and the Western Athletic Conference), provided that said champion ranked in the top twelve in the final BCS rankings. Every season since this rule change was implemented, schools from non-BCS conferences played in BCS bowl games. In 2009, Boise State played TCU in the Fiesta Bowl, the first time two schools from non-BCS conferences played each other in a BCS bowl game.
Early players, teams, and leagues (1892–1919)
In the early 20th century, football began to catch on in the general population of the United States and was the subject of intense competition and rivalry, albeit of a localized nature. Although payments to players were considered unsporting and dishonorable at the time, a Pittsburgh area club, the Allegheny Athletic Association, surreptitiously hired former Yale All-American guard William "Pudge" Heffelfinger. On November 12, 1892, Heffelfinger became the first known professional football player. He was paid $500 to play in a game against the Pittsburgh Athletic Club. Heffelfinger picked up a Pittsburgh fumble and ran 35 yards for a touchdown, winning the game 4–0 for Allegheny. Although observers held suspicions, the payment remained a secret for years.
On September 3, 1895 the first wholly professional game was played, in Latrobe, Pennsylvania, between the Latrobe Athletic Association and the Jeannette Athletic Club. Latrobe won the contest 12–0. During this game, Latrobe's quarterback, John Brallier became the first player to openly admit to being paid to play football. He was paid $10 plus expenses to play. In 1897, the Latrobe Athletic Association paid all of its players for the whole season, becoming the first fully professional football team. In 1898, William Chase Temple took over the team payments for the Duquesne Country and Athletic Club, a professional football team based in Pittsburgh from 1895 until 1900, becoming the first known individual football club owner. A year later in 1899, the Morgan Athletic Club, on the South Side of Chicago, was founded. This team later became the Chicago Cardinals, and now is known as the Arizona Cardinals, making them the oldest continuously operating professional football team.
The first known professional football league, known as the National Football League (not the same as the modern league) began play in 1902 when several baseball clubs formed football teams to play in the league, including the Philadelphia Athletics, Pittsburgh Pirates and the Philadelphia Phillies. The Pirates' team the Pittsburgh Stars were awarded the league championship. However the Philadelphia Football Athletics and Philadelphia Football Phillies also claimed the title. A five-team tournament, known as the World Series of Football was organized by Tom O'Rouke, the manager of Madison Square Garden. The event featured the first-ever indoor pro football games. The very first professional indoor game came on December 29, 1902, when the Syracuse Athletic Club defeated the "New York team" 5–0. Syracuse would go onto win the 1902 Series, while the Franklin Athletic Club won the Series in 1903. The World Series only lasted two seasons.
The game moved west into Ohio which became the center of professional football during the early decades of the 20th century. Small towns such as Massillon, Akron, Portsmouth, and Canton all supported professional teams in a loose coalition known as the "Ohio League," the direct predecessor to today's National Football League. In 1906 the Canton Bulldogs–Massillon Tigers betting scandal became the first major scandal in professional football in the United States. It was more notably the first known case of professional gamblers attempting to fix a professional sport. Although the Massillon Tigers could not prove that the Canton Bulldogs had thrown the second game, the scandal tarnished the Bulldogs name and reportedly helped ruin professional football in Ohio until the mid-1910s. In 1915, the reformed Canton Bulldogs signed former Olympian and Carlisle Indian School standout Jim Thorpe to a contract. Thorpe became the face of professional football for the next several years and was present at the founding of the National Football League five years later. A disruption in play in 1918 (due to World War I and flu pandemic) allowed the New York Pro Football League to pick up some of the Ohio League's talent; the NYPFL had coalesced around 1916, but efforts to challenge the Ohio teams were largely unsuccessful until after the suspension. By 1919, the Ohio League and the New York league were on relatively equal footing with both each other and with teams clustered around major cities such as Philadelphia, Chicago and Detroit.
In 1923, Adam Martin Wyant, a guard for the Greensburg Athletic Association, from 1895 to 1897, became the first professional football player to be elected to the United States Congress. He was a Republican who represented Pennsylvania's 22nd, and later 31st congressional district, for a total of 12 years.
Early years of the NFL (1920–1945)
The 1919 expansion of top-level professional football threatened to drastically increase the cost of the game by sparking bidding wars. The various regional circuits determined that forming a league, with enforceable rules, would mitigate these problems.
In 1920, the American Professional Football Association, was founded, in a meeting at a Hupmobile car dealership in Canton, Ohio. Jim Thorpe was elected the league's first president. After several more meetings, the league's membership was formalized. The original teams were:
- Akron Pros
- Buffalo All-Americans
- Canton Bulldogs
- Chicago Tigers
- Cleveland Indians
- Columbus Panhandles
- Dayton Triangles
- Decatur Staleys
- Detroit Heralds
- Hammond Pros
- Muncie Flyers
- Racine Cardinals
- Rochester Jeffersons
- Rock Island Independents
In its early years the league was little more than a formal agreement between teams to play each other and to declare a champion at season's end. Teams were still permitted to play non-league members. The 1920 season saw several teams drop out and fail to play through their schedule. Only four teams: Akron, Buffalo, Canton, and Decatur, finished the schedule. Akron claimed the first league champion, with the only undefeated record among the remaining teams.
In 1921, several more teams joined the league, increasing the membership to 22 teams. Among the new additions were the Green Bay Packers, which now has the record for longest use of an unchanged team name. Also in 1921, A. E. Staley, the owner of the Decatur Staleys, sold the team to player-coach George Halas, who went on to become one of the most important figures in the first half century of the NFL. In 1921, Halas moved the team to Chicago, but retained the Staleys nickname. In 1922 the team was renamed the Chicago Bears. The Staleys won the 1921 AFPA Championship, over the Buffalo All-Americans in an event later referred to as the "Staley Swindle".
By the mid-1920s, NFL membership had grown to 25 teams, and a rival league known as the American Football League was formed. The rival AFL folded after a single season, but it symbolized a growing interest in the professional game. Several college stars joined the NFL, most notably Red Grange from the University of Illinois, who was taken on a famous barnstorming tour in 1925 by the Chicago Bears. Another scandal that season centered around a 1925 game between the Chicago Cardinals and the Milwaukee Badgers. The scandal involved a Chicago player, Art Folz, hiring a group of high school football players to play for the Milwaukee Badgers, against the Cardinals. This would ensure an inferior opponent for Chicago. The game was used to help prop up their win-loss percentage and as a chance of wrestling away the 1925 Championship away from the first place Pottsville Maroons. All parties were severely punished initially, however a few months later the punishments were rescinded. Also that year a controversial dispute stripped the NFL title from the Maroons and awarded it to the Cardinals.
1932 NFL playoff game
At the end of the 1932 season, the Chicago Bears and the Portsmouth Spartans were tied with the best regular-season records. To determine the champion, the league voted to hold its first playoff game. Because of cold weather, the game was held indoors at Chicago Stadium, which forced some temporary rule changes. Chicago won, 9–0. The playoff proved so popular that the league reorganized into two divisions for the 1933 season, with the winners advancing to a scheduled championship game. A number of new rule changes were also instituted: the goal posts were moved forward to the goal line, every play started from between the hash marks, and forward passes could originate from anywhere behind the line of scrimmage (instead of the previous five yards behind). In 1936, the NFL instituted the first ever draft of college players. The first selection was Heisman Trophy winner Jay Berwanger, but he declined to play professionally. Also in that year, another AFL formed, but it also lasted only two seasons.
Stability and growth of the NFL (1936–1957)
The 1930s represented an important time of transition for the NFL. League membership was fluid prior to the mid 1930s. 1936 was the first year where there were no franchise moves, prior to that year 51 teams had gone defunct. In 1941, the NFL named its first Commissioner, Elmer Layden. The new office replaced that of President. Layden held the job for five years, before being replaced by Pittsburgh Steelers co-owner Bert Bell in 1946.
During World War II, a player shortage led to a shrinking of the league as several teams folded and others merged. Among the short-lived merged teams were the Steagles (Pittsburgh and Philadelphia) in 1943, the Carpets (Chicago Cardinals and Pittsburgh) in 1944, and a team formed from the merger of the Brooklyn Dodgers and the Boston Yanks in 1945.
1946 was an important year in the history of professional football, as that was the year when the league integrated. The Los Angeles Rams signed two African American players, Kenny Washington and Woody Strode. Also that year, a competing league, the All-America Football Conference (AAFC), began operation.
During the 1950s, additional teams entered the league. In 1950, the AAFC folded, and three teams from that league were absorbed into the NFL: the Cleveland Browns (who had won the AAFC Championship every year of the league's existence), the San Francisco 49ers, and the Baltimore Colts (not the same as the modern franchise, this version folded after one year). The remaining players were chosen by the now 13 NFL teams in a dispersal draft. Also in 1950, the Los Angeles Rams became the first team to televise its entire schedule, marking the beginning of an important relationship between television and professional football. In 1952, the Dallas Texans went defunct, becoming the last NFL franchise to do so. The following year a new Baltimore Colts franchise formed to take over the assets of the Texans. The players' union, known as the NFL Players Association, formed in 1956.
NFL supremacy (1958–present)
The Greatest Game Ever Played
At the conclusion of the 1958 NFL season, the Baltimore Colts and the New York Giants met at Yankee Stadium to determine the league champion. Tied after 60 minutes of play, it became the first NFL game to go into sudden death overtime. The final score was Baltimore Colts 23, New York Giants 17. The game has since become widely known as "the Greatest Game Ever Played". It was carried live on the NBC television network, and the national exposure it provided the league has been cited as a watershed moment in professional football history, helping propel the NFL to become one of the most popular sports leagues in the United States. Journalist Tex Maule said of the contest, "This, for the first time, was a truly epic game which inflamed the imagination of a national audience."
American Football League and merger
In 1959, longtime NFL commissioner Bert Bell died of a heart attack while attending an Eagles/Steelers game at Franklin Field. That same year, Dallas, Texas businessman Lamar Hunt led the formation of the rival American Football League, the fourth such league to bear that name, with war hero and former South Dakota Governor Joe Foss as its Commissioner. Unlike the earlier rival leagues, and bolstered by television exposure, the AFL posed a significant threat to NFL dominance of the professional football world. With the exception of Los Angeles and New York, the AFL avoided placing teams in markets where they directly competed with established NFL franchises. In 1960, the AFL began play with eight teams and a double round-robin schedule of fourteen games. New NFL commissioner Pete Rozelle took office the same year.
The AFL became a viable alternative to the NFL as it made a concerted effort to attract established talent away from the NFL, signing half of the NFL's first-round draft choices in 1960. The AFL worked hard to secure top college players, many from sources virtually untapped by the established league: small colleges and predominantly black colleges. Two of the eight coaches of the Original Eight AFL franchises, Hank Stram (Texans/Chiefs) and Sid Gillman (Chargers) eventually were inducted to the Hall of Fame. Led by Oakland Raiders owner and AFL commissioner Al Davis, the AFL established a "war chest" to entice top talent with higher pay than they got from the NFL. Former Green Bay Packers quarterback Babe Parilli became a star for the Boston Patriots during the early years of the AFL, and University of Alabama passer Joe Namath rejected the NFL to play for the New York Jets. Namath became the face of the league as it reached its height of popularity in the mid-1960s. Davis's methods worked, and in 1966, the junior league forced a partial merger with the NFL. The two leagues agreed to have a common draft and play in a common season-ending championship game, known as the AFL-NFL World Championship. Two years later, the game's name was changed to the Super Bowl. AFL teams won the next two Super Bowls, and in 1970, the two leagues merged to form a new 26-team league. The resulting newly expanded NFL eventually incorporated some of the innovations that led to the AFL's success, such as including names on player's jerseys, official scoreboard clocks, national television contracts, and sharing of gate and broadcasting revenues between home and visiting teams.
The NFL continued to grow, eventually adopting some innovations of the AFL, including the two-point PAT conversion. It has expanded several times to its current 32-team membership, and the Super Bowl has become more than simply a football championship. One of the most popular televised events annually in the United States, it has become a major source of advertising revenue for the television networks that have carried it and it serves as a means for advertisers to debut elaborate and expensive commercials for their products. The NFL has grown to become the most popular spectator sports league in the United States.
One of the things that has marked the modern NFL as different from other major professional sports leagues is the apparent parity between its 32 teams. While from time to time, dominant teams have arisen, the league has been cited as one of the few where every team has a realistic chance of winning the championship from year to year. The league's complex labor agreement with its players' union, which mandates a hard salary cap and revenue sharing between its clubs, prevents the richest teams from stockpiling the best players and gives even teams in smaller cities such as Green Bay and New Orleans the opportunity to compete for the Super Bowl. One of the chief architects of this labor agreement was former NFL commissioner Paul Tagliabue, who presided over the league from 1989 to 2006. In addition to providing parity between the clubs, the current labor contract, established in 1993 and renewed in 1998 and 2006, has kept player salaries low—the lowest among the four major league sports in the United States— and has helped make the NFL the only major American professional sports league since 1993 not to suffer any player strike or work stoppage.
Since taking over as commissioner before the 2006 season, Roger Goodell has made player conduct a priority of his office. Since taking office, several high-profile players have experienced trouble with the law, from Adam "Pacman" Jones to Michael Vick. In these and other cases, Commissioner Goodell has mandated lengthy suspensions for players who fall outside of acceptable conduct limits.
Other professional leagues
Several other professional football leagues have been formed since the AFL-NFL merger, though none have had the success of the AFL. In 1974, the World Football League formed and was able to attract such stars as Larry Csonka away from the NFL with lucrative contracts. However, most of the WFL franchises were insolvent and the league folded in 1975; the Memphis Southmen, the team that had signed Csonka and the most financially stable of the teams, unsuccessfully sued to join the NFL.
In 1982, the United States Football League formed as a spring league, and enjoyed moderate success during its first two seasons behind such stars as Jim Kelly and Herschel Walker. It moved its schedule to the fall in 1985, and tried to compete with the NFL directly, but it was unable to do so and folded, despite winning an anti-trust suit against the older league.
The NFL founded a developmental league known as the World League of American Football with teams based in the United States, Canada, and Europe. The WLAF ran for two years, from 1991 to 1992. The league went on a two-year hiatus before reorganizing as NFL Europe in 1995, with teams only in European cities. The name of the league was changed to NFL Europa in 2006. After the 2007 season, the NFL announced that it was closing down the league to focus its international marketing efforts in other ways, such as playing NFL regular season games in cities outside of the U.S.
In 2001, the XFL was formed as a joint venture between the World Wrestling Federation and the NBC television network. It folded after one season because of a lack of fan interest. However, XFL stars such as Tommy Maddox and Rod "He Hate Me" Smart later saw success in the NFL.
The United Football League is a five-team fully professional league which played its first season in October–November 2009. Involved in this league are Mark Cuban, media mogul and owner of the National Basketball Association's Dallas Mavericks and William Hambrecht, a prominent Wall Street investor.
Youth and high school football
American football is a popular participatory sport among youth. One of the earliest youth football organizations was founded in Philadelphia, in 1929, as the Junior Football Conference. Organizer Joe Tomlin started the league to provide activities and guidance for teenage boys who were vandalizing the factory he owned. The original four-team league expanded to sixteen teams in 1933 when Pop Warner, who had just been hired as the new coach of the Temple University football team, agreed to give a lecture to the boys in the league. In his honor, the league was renamed the Pop Warner Conference.
Today, Pop Warner Little Scholars—as the program is now known—enrolls over 300,000 young boys and girls ages 5–16 in over 5000 football and cheerleading squads, and has affiliate programs in Mexico and Japan. Other organizations, such as the Police Athletic League, Upward, and the National Football League's NFL Youth Football Program also manage various youth football leagues.
Football is a popular sport for high schools in the United States. The National Federation of State High School Associations (NFHS) was founded in 1920 as an umbrella organization for state-level organizations that manage high school sports, including high school football. The NFHS publishes the rules followed by most local high school football associations. More than 13,000 high schools participate in football, and in some places high school teams play in stadiums that rival college-level facilities. In Denton, Texas, for example, a 12,000 seat, $21,000,000 stadium hosts two local high school football teams. The growth of high school football and its impact on small town communities has been documented by landmark non-fiction works such as the 1990 book Friday Night Lights and the subsequent fictionalized film and television series.
American football outside the United States
American football has been played outside the US since the 1920s and accelerated in popularity after World War II, especially in countries with large numbers of U.S. military personnel, who often formed a substantial proportion of the players and spectators.
In 1998, the International Federation of American Football, was formed to coordinate international amateur competition. At present, 45 associations from the Americas, Europe, Asia and Oceania are organized within the IFAF, which claims to represent 23 million amateur athletes. The IFAF, which is based in Paris, France, organizes the quadrennial American Football World Cup.
Until 2007, Japan dominated amateur football outside of the USA. The Japanese national team won the first two world cups—hosted by Italy in 1999 and Germany in 2003—defeating Mexico in the play-off on both occasions. Japan had never lost a game until it went down at home, 23–20, to the US Amateur Team in the final of the 2007 World Cup.
A long term goal of the IFAF is for American football to be accepted by the International Olympic Committee as an Olympic sport. The only time that the sport was played was at the 1932 Summer Olympics in Los Angeles, but as a demonstration sport. Among the various problems the IFAF has to solve in order to be accepted by the IOC are building a competitive women's division, expanding the sport into Africa, and overcoming the current worldwide competitive imbalance that is in favor of American teams.
American football has been played in Mexico since the early 1920s, and is a strong minority sport at Mexican colleges and universities, mainly in Mexico City. Over successive decades, more universities and colleges joined the championship, and four categories, called fuerzas, were created. The First Fuerza became the National League in 1970. In 1978, this was reorganized under the name Organización Nacional Estudiantil de Fútbol Americano (ONEFA).
The Japan American Football Association was founded in 1934 with three collegiate teams: Rikkyo, Meiji and Waseda. In 1937, an allstar game involving teams representing eastern and western Japan attracted over 25,000 spectators. Recently, the Rice Bowl has drawn crowds of over 60,000.
American football in Europe first began as a four-team tournament between NATO allies on the west coast of Italy. The game began to take hold in Italy, with the first game between two European teams occurring between teams from Piacenza and Legnano. The German Football League was formed in 1979. By 1981, the first international games between European nations occurred, as a two game series between German and Italian teams.
The first European governing body, the American European Football Federation (AEFF) was formed in 1982 by representatives from Finland, Italy, Germany, Austria, and France. The league expanded in 1985 to include Switzerland, the Netherlands, and Great Britain and changed its name to the European Football League. Now known as the European Federation of American Football, it now is made up of 14 member nations. Today, there are approximately 800 American football clubs throughout Europe, with the American football Association of Germany (AFVD) overseeing more than 230 clubs.
Similar codes of football
Other codes of football share a common history with American football. Canadian football is a form of the game that evolved parallel to American football. While both games share a common history, there are some important differences between the two. A more modern sport that derives from American football is Arena football, designed to be played indoors inside of hockey or basketball arenas. The game was invented in 1981 by Jim Foster and the Arena Football League was founded in 1987 as the first major professional league to play the sport. Several other indoor football leagues have since been founded and continue to play today.
American football's parent sport of rugby continued to evolve. Today, two distinct codes known as rugby union and rugby league are played throughout the world. Since the two codes split following a schism on how the sport should be managed in 1895, the history of rugby league and the history of rugby union have evolved separately. Both codes have adopted innovations parallel to the American game; the rugby union scoring system is almost identical to the American game, while rugby league uses a gridiron-style field and a six-tackle rule similar to the system of downs in American Football.
