History of the National Football League
The history of the National Football League has roots spanning as far back as 1892 when former Yale All-American guard William Heffelfinger was paid $500 by the Allegheny Athletic Association to play in a game against the Pittsburgh Athletic Club, making him the first ever professional football player. However it wasn't until 1920 that American football achieved a league of any true organization. The American Professional Football Association was formed on September 17, 1920 and included ten teams from four different states. However the APFA lasted only two seasons when it was reorganized on June 24, 1922 into the National Football League. Only two teams currently in the NFL, the Decatur Staleys (now the Chicago Bears) and the Chicago Cardinals (now the Arizona Cardinals), are founding members. The Green Bay Packers, founded 1919 (joined the NFL in 1921), is the oldest NFL franchise in continuous operation with the same name in the same location.
League membership gradually stabilized throughout the 1920s and 1930s as the league adopted progressively more formal organization. The first official championship game was held in 1933. The NFL stopped signing black players in 1927 but reintegrated in 1946 following World War II. Other changes followed after the war; the office of league President evolved into the more powerful Commissioner post, mirroring a similar move in Major League Baseball. Teams became more financially viable, the last team folding in 1952. By 1958, when that season's NFL championship game became known as "The Greatest Game Ever Played", the NFL was on its way to becoming one of the most popular sports leagues in the United States.
The rival American Football League was founded in 1960. It was very successful, and forced a merger with the older NFL that resulted in a greatly expanded league and the creation of the Super Bowl, which has become the most-watched annual sporting event in the United States. The league continued to expand to its current size of 32 teams. A series of labor agreements during the 1990s and increasingly large television contracts has helped keep the league one of the most profitable in the U.S., and the only major league in the U.S. since 1990 to avoid a work stoppage that resulted in the loss of regular-season games.

Professional football was primarily a regional sport in the early part of the 20th century, with most informal circuits centered around a single state or region with only limited play outside state lines. There were no national leagues or tournaments for the professional game, despite numerous attempts: an earlier National Football League (backed by what would become Major League Baseball) was unable to expand beyond Pennsylvania in 1902, the New York City-based World Series of Pro Football tournament disbanded after two seasons and lack of fan interest. and other attempts to either combine existing circuits or create new ones from scratch never materialized.
By the late 1910s, the regional circuits had organized into more or less leagues of varying degrees of organization. One of the most prominent at the time was the Ohio League, which boasted the services of legendary American Indian athlete Jim Thorpe, among other stars. Another was the somewhat lower-caliber, but better-organized, New York Pro Championship; two of the New York circuit's best teams, the Rochester Jeffersons and the Buffalo All-Stars, went on a barnstorming tour of Ohio. After Lyons's Jeffersons played, and lost badly to, Thorpe's Canton Bulldogs in a 1917 match, Jeffersons owner Leo Lyons (believing that the foundation of a league could build a sport that rivaled baseball, which then held an effective monopoly on professional sport, in popularity) suggested to Thorpe that a league be formed.
Lyons' vision of a national league of existing football clubs (which, at the time, was competing with another proposed league, again backed by baseball) was cut short by the United States' entry into World War I and further hampered by a flu pandemic in 1918, which forced most of the Ohio League teams to suspend operations due to either travel restrictions or loss of players to the war effort. New York's teams, although they were forced to reduce their schedules, continued and (along with the few other remaining teams that survived the suspension, including the OL's Dayton Triangles and Michigan's Detroit Heralds) picked up many of the stars that remained stateside. This had the effect of spreading out the talent across a broader geographic area. Over the course of 1919, as professional football had increased in parity, teams began reaching out and participating in more barnstorming tours. By then, two informal but distinct interstate circuits had developed: one around the Eastern Seaboard (particularly New York City, New Jersey and Philadelphia) that played mostly on Saturdays due to blue laws, and another centered around the Midwestern region (Illinois, Indiana, Minnesota, Wisconsin, Ohio, and upstate New York) that played on Sundays. It was the latter that formed the basis of what would eventually become the modern National Football League.
Ohio's teams went along with the idea in the face of escalating costs: several bidding wars in the early 1900s, both in Pennsylvania and Ohio, had damaged the sport significantly, and another bidding war was about to erupt if something was not done. By forming a national league, teams reasoned that it would eliminate the practices of looting other teams' rosters and concentrating top talent in only a few teams, thus distributing talent more evenly and efficiently thereby reducing costs for each individual team while still keeping a top-level product on the field.
Birth of a new league
On August 20, 1920, at a Hupmobile dealership in Canton, Ohio, the league was formalized, originally as the American Professional Football Conference, initially consisting only of the Ohio League teams, although some of the teams declined participation. One month later on September 17, the league was renamed the American Professional Football Association, adding Buffalo and Rochester from the New York league, and Detroit, Hammond (a suburban Chicago squad), and several other teams from nearby circuits. The eleven founding teams initially struck an agreement over player poaching and the declaration of an end-of-season champion. Thorpe, while still playing for the Bulldogs, was elected president. Only four of the founding teams finished the 1920 schedule and the undefeated Akron Pros claimed the first championship. Membership of the league increased to 22 teams – including more of the New York teams – in 1921, but throughout the 1920s the membership was unstable and the league was not a major national sport. On June 24, 1922, the organization, now headquartered in Columbus, Ohio, changed its title a final time to the National Football League.
Two charter members, the Chicago Cardinals (now the Arizona Cardinals) and the Decatur Staleys (now the Chicago Bears), are still in existence. The Green Bay Packers franchise, founded in 1919, is the oldest team not to change locations, but did not begin league play until 1921. The New York Football Giants joined in 1925, followed by the Portsmouth Spartans in 1930, relocating to Detroit in 1934 to become the Lions.[dead link] The Indianapolis Colts franchise traces its history through several predecessors, including one of the league's founding teams – the Dayton Triangles – but is considered a separate franchise from those teams and was founded as the Baltimore Colts in 1953. Although the original NFL teams representing Buffalo, Cleveland, Chicago and Detroit no longer exist, replacement franchises have since been established for those cities.
Early championships were awarded to the team with the best won-lost record, initially rather haphazardly, as some teams played more or fewer games than others, or scheduled games against non-league, amateur or collegiate teams; this led to the title being decided on a tiebreaker in 1921, a disputed title in 1925, and the scheduling of an impromptu indoor playoff game in 1932.
In league meetings prior to the 1933 season, three new teams, the Pirates, the Cincinnati Reds and the Eagles, were admitted to the NFL. Ten teams were then in the NFL and, at George Preston Marshall's urging, with Halas' support, NFL was reorganized into an Eastern Division and a Western Division. In the Eastern Division were the Philadelphia Eagles, Brooklyn Dodgers, New York Giants, Boston Redskins, and the Pittsburgh Pirates. In the Western Division were the Chicago Bears, Portsmouth Spartans, Chicago Cardinals, Green Bay Packers, and the Cincinnati Reds. Furthermore, the two owners convinced the league to have the two division winners meet in a NFL Championship Game.
By 1934, all of the small-town teams, with the exception of the Green Bay Packers, had moved to or been replaced by teams in big cities, and even Green Bay had begun to play a portion of its home schedule in much larger Milwaukee for more support (a practice they continued well into the 1990s). In 1941, the corporate headquarters moved from Columbus, Ohio to Chicago. During the early years of the league, rather than coming up with original team names, many NFL teams simply chose the name of the Major League Baseball team in the same city. Thus the Pittsburgh Steelers were the "Pittsburgh Pirates" for the first seven years of existence and other teams such as the Brooklyn Dodgers, Cleveland Indians, Cincinnati Reds, Detroit Tigers, New York Yankees, Washington Senators and Buffalo Bisons all represented the NFL at one time or another.
An annual draft of college players was first held in 1936. The first televised NFL game was on October 22, 1939 in a game the Eagles lost 23-14 to the host Dodgers at Ebbets Field. It was during this era, however, that the NFL became segregated: there were no black players in professional football in the United States between 1933 and 1945, mainly due to the influence of George Preston Marshall, who entered the league in 1932 as the owner of the Boston Braves. Other NFL owners emulated Marshall's whites-only policy to mollify southern fans, and even after the NFL's color barrier had been broken in the 1950s, Marshall's Washington Redskins remained all-white until forced to integrate by the Kennedy administration in 1962. Despite his bigotry, Marshall was selected as a charter member of the NFL-inspired Pro Football Hall of Fame.
College football was the bigger attraction, but by the end of World War II, pro football began to rival the college game for fans' attention. Rule changes and innovations such as the T formation led to a faster-paced, higher-scoring game. The league also expanded out of its eastern and midwestern cradle; in 1945, the Cleveland Rams moved to Los Angeles, becoming the first big-league sports franchise on the West Coast. In 1950, the NFL accepted three teams – the Cleveland Browns, San Francisco 49ers, and Baltimore Colts – from the defunct All-America Football Conference, expanding to thirteen clubs. In 1958, the Baltimore Colts and New York Giants played "The Greatest Game Ever Played" for the championship. Being the first nationally televised football game, along with its thrilling ending greatly increased the popularity of the NFL. Through these breakthroughs, pro football finally earned its place as a major sport.
At its inception in 1920, the NFL's precursor, the American Professional Football Association, had several minority players, including African-American players: between 1920 and 1926, nine black players suited up for NFL squads. It was also common, due to the number of talented players that were produced by the Carlisle Indian School's football team, to see teams (both inside and outside the NFL) openly market Native Americans; in fact, the Oorang Indians of 1922 to 1923 consisted entirely of Native American talent. Running back Walter Achiu and quarterback Arthur Matsu, both of the Dayton Triangles, were the first Asian-American players in the NFL, having joined the league in 1927 and 1928 respectively.
However, since Carlisle had closed in 1918, the talent pool of Indians had dried up. Meanwhile, all black players in the NFL (including future Hall of Famer Fritz Pollard) were summarily kicked out prior to the 1927 season for reasons unexplained. From 1928 to 1932, no more than one black player could be found in the league each season, and none played more than two seasons. In 1933, there were two: Joe Lillard and Ray Kemp. Lillard was kicked off the Chicago Cardinals for fighting, while Kemp left to pursue what would become a successful coaching career. The moves left the league as all-white, and Boston Redskins owner George Preston Marshall allegedly used his pressure to keep it that way for the next several years, though each team's internal politics and cronyism, as well as the rising tide of racism in the United States as a whole, also played a significant role. Even during the wartime years, when much of the NFL's talent was overseas fighting World War II, players such as Kenny Washington who stayed in the United States were still passed up in favor of white players with normally debilitating medical conditions such as partial blindness.
NFL integration occurred only when the Cleveland Rams wanted to move to Los Angeles, and the venue, the Los Angeles Coliseum, required them to integrate their team. They then signed two black players, Kenny Washington and Woody Strode. Other NFL teams eventually followed suit, but Marshall refused to integrate the Redskins until forced to by the Kennedy administration as a pre-condition for using D.C. Stadium (now RFK Stadium). In spite of this open bias, Marshall was elected to the NFL's Pro Football Hall of Fame in 1963. In 1946, the Cleveland Browns of a rival Professional Football league, the All-America Football Conference, signed two black players. By 1960, the NFL's new competitor, the American Football League, actively recruited players from smaller predominantly black colleges that had been largely ignored by the NFL, giving those schools' black players the opportunity to play professional football. Early AFL teams averaged more blacks than did their NFL counterparts.
However, despite the NFL's previous segregationist policies, the clear competitive advantage of AFL teams with liberal signing policies affected the NFL's drafts. By 1969, a comparison of the two league's championship team photos showed the AFL's Chiefs with 23 black players out of 51 players (45%) pictured, while the NFL's Vikings had 11 blacks, of 42 players (26%) in the photo. Chiefs players have been quoted as saying that one motivating factor in their defeat of the Vikings was their pride in their diverse squad. Recent surveys have shown that the current, post-merger NFL is approximately 67–71% non-white (this includes African Americans, Polynesians, non-white Hispanics, Asians, and people that are mixed race), significantly higher than the national average.
On March 3, 2013, Lauren Silberman became the first woman to ever try out for the National Football League when she appeared as a kicker at the NFL Regional Scouting Combine in Florham Park, New Jersey. However, after two poor kicks, Silberman left the field, citing an injury to her quadriceps; the tryout was suspected by members of the press and public as being nothing more than a publicity stunt.
While there have been a scattering of professional female football players in semi-pro football (Patricia Palinkas, Katie Hnida and the still active Julie Harshbarger among them) and in college football, no woman with prior experience as an American football kicker has attempted to make an NFL roster.
Merger with the American Football League
The NFL held a monopoly on professional football in the United States for most of the 1950s, a rare occurrence for a league that had at least one competing league in every year since 1934. By 1960, a group of potential professional football owners that would become known as the Foolish Club had become frustrated with their efforts to buy into the NFL (some were NFL franchise minority owners such as Harry Wismer and Ralph Wilson; others, such as Lamar Hunt and Bud Adams, had tried but failed to buy NFL teams) and formed a new league, the American Football League. It was the eighth professional football league to use the name and the fourth to be universally considered a major-league competitor to the NFL. The AFL would prove to be the NFL's most formidable challenger to date.
By the middle of the 1960s competition for players, including separate college drafts, was driving up player salaries. In 1965, in the most high profile such contest and a major boost to the AFL, University of Alabama quarterback Joe Namath signed with the New York Jets rather than the NFL's St. Louis Cardinals for a then-record $427,000. In 1966, the NFL's New York Giants broke an informal agreement and signed placekicker Pete Gogolak, who was under contract to the AFL's Buffalo Bills. Then AFL Commissioner Al Davis embarked on a campaign to sign players away from the NFL, especially quarterbacks, but behind the scenes a number of NFL team owners began action to end the detrimental rivalry.
Several NFL franchises led by Cowboys General Manager Tex Schramm asked to meet with AFL owners to negotiate a merger. In an agreement brokered by Schramm and AFL founder Lamar Hunt, the two leagues announced their merger deal on June 8, 1966. The leagues would thenceforth hold a Common Draft and an end-of-season World Championship Game between the two league champions (later known as the Super Bowl and reverting to simply an NFL championship game). Still another city received an NFL franchise thanks to the AFL, as New Orleans was awarded an NFL team after Louisiana's federal Congressmen pushed for the passage of Public Law 89-800, which permitted the merger and exempted the action from Anti-Trust restrictions. The monopoly that would be created needed to be legitimized by an act of Congress. In 1970, the leagues fully merged under the name National Football League and divided into two conferences of an equal number of teams. There was a financial settlement, with the AFL teams paying a combined $18 million over 20 years.
Although the AFL's identity was subsumed by the NFL, the NFL eventually adopted many of the AFL's innovations including the on-field game clock, names on player jerseys, recruiting at small and predominantly black colleges, gate and television revenue-sharing, establishment of southern franchises, and more wide-open offensive rules.
Unlike previous armed conflicts such as World War I and World War II, both of which effectively stopped or dramatically reduced the amount of professional football played in the United States, both the AFL and NFL were largely unaffected by the Vietnam War and did not lose a significant number of players to the war draft. There is at least one recorded incidence of the NFL using champagne units to keep its players from being sent overseas (the Dallas Cowboys used the Texas Air National Guard's 147th Fighter Interceptor Group, a well-known champagne unit to shield seven Cowboys players from combat in Vietnam). Bob Kalsu, then a player with the AFL's Buffalo Bills, left the team to serve in Vietnam and died in combat, becoming the first (and, until Pat Tillman's death in Afghanistan over 30 years later, only) active NFL or AFL player to die in war during his playing career.
In the 1970s and 1980s, the NFL solidified its dominance as America's top spectator sport and its important role in American culture. The Super Bowl became an unofficial national holiday and the top-rated TV program most years. Monday Night Football, which first aired in 1970, brought in high ratings by mixing sports and entertainment. Rule changes in the late 1970s ensured a fast-paced game with lots of passing to attract the casual fan.
The World Football League was the first post-merger challenge to the NFL's dominance, and in 1974, successfully lured some top NFL talent to its league and prompted a few rules changes in the NFL. However, financial problems led the league to fold halfway through its 1975 season. Two teams, the Birmingham Vulcans and Memphis Southmen, made unsuccessful efforts to move from the WFL to the NFL.
The founding of the United States Football League in the early 1980s was the biggest challenge to the NFL in the post-merger era. The USFL was a well-financed competitor with big-name players and a national television contract. However, the USFL failed to make money and folded after three years. The USFL filed a successful anti-trust lawsuit against the NFL, but the remedies were minimal, and mismanagement (most notably, a planned move of its niche spring football season to a head-to-head competition in the fall) led to the league's collapse.
2001 saw the establishment of the XFL, an attempt by Vince McMahon and NBC, which had lost the NFL broadcast rights for that year, to compete with the league; the XFL folded after just one season. Unlike the WFL and USFL, the XFL had no impact on the NFL's rules or franchise locations (its attempts at innovations were often ridiculed, though one innovation, the above the field Skycam which originated in the XFL, became a regular part of NFL telecasts), but a few NFL players used the XFL to relaunch their careers. The United Football League, which began play in 2009, had originally planned to take a direct challenge to the NFL with NFL-comparable salaries and teams in New York City and Los Angeles, but the UFL never did play in those cities (an ostensibly New York team played in Long Island and New Jersey), cut back its salaries, and instead opted for a complementary approach with teams in cities such as Las Vegas, Sacramento and Omaha. Several other upstart leagues (such as the AAFL and UNGL) are also planned, but they have all been set back by financial and organizational problems, and none have taken the field yet, while the Stars Football League began play on a regional basis in summer 2011 with a significantly abbreviated schedule. All of these proposed leagues will play in the spring and have no plans to compete with the NFL, either for talent or for fans.
On August 31, 2007, a story in USA Today unveiled the first changes to the league's shield logo since 1980, which took effect with the 2008 season. The redesign reduced the number of stars in the logo from 25 (which were found not to have a meaning beyond being decorative) to eight (for each of the league's divisions), repositioned the football in the manner of the Vince Lombardi Trophy, and changed the NFL letters to a straight, serifed font. The redesign was created with television and digital media, along with clothing, in mind. The shield logo itself dates back to the 1940s.
In recent years, the NFL has expanded into new markets and ventures outside of the United States, beginning with a regular series of exhibition games known as the American Bowl, then with a European based developmental league culminating in the now defunct NFL Europa, and starting in 2005 the league began hosting regular season games outside the United States, the first in Mexico City, Mexico, and then from 2007 hosting games London, England, and from 2008 in Toronto, Canada.
The American Bowl games began in 1986 and continued until 2005 at various sites in countries around the world. Then in 1991, the league formed the World League of American Football, later known as NFL Europe and still later as NFL Europa, a developmental league that had teams in Britain, Germany, Spain, and the Netherlands. The NFL shut down the program in June 2007.
The league played a regular-season NFL game in Mexico City in 2005, the first-ever NFL regular season game held outside the United States, and marketed across the league as the Fútbol Americano game. On October 28, 2007, a regular season game between the Miami Dolphins and the New York Giants was held outside of North America for the first time in Wembley Stadium, the 90,000-seat national stadium, in London. It was a financial success with nearly 40,000 tickets sold within ninety minutes of the start of sales, and a game-day attendance of over 80,000. In 2008, the New Orleans Saints and San Diego Chargers played at Wembley, and in October 2009, the New England Patriots and Tampa Bay Buccaneers met. In 2010, it was the Denver Broncos and the San Francisco 49ers that played in London. Starting from the 2008-09 season, building on league links with Toronto, the Buffalo Bills play an annual home game in Toronto's Rogers Centre, marketed by the team as the Bills Toronto Series.
After 100 years of American football influence in Mexican territory, in 1998 the NFL opened a representation office in Mexico, called NFL México, as the NFL identified Mexico as a key market outside the United States due to proximity and tradition. The Mexican office handles sponsorship, licencing, detail dealers, sport culture, broadcasting, public relationships and community service.[dead link]
Franchise relocations and mergers
In the early years, the league was not stable and teams moved frequently. Franchise mergers were popular during World War II in response to the scarcity of players. An example of this was the Steagles, temporarily formed as a merger between the Pittsburgh Steelers and Philadelphia Eagles.
Franchise moves became far more controversial in the late twentieth century when a vastly more popular NFL was free from financial instability and allowed many franchises to abandon long-held strongholds for perceived financially greener pastures. This was done in spite of the promises to Congress by Pete Rozelle in 1966 that if the AFL-NFL merger were allowed, no city would lose its franchise. Those promises were made to ensure passage of PL 89-800, which granted anti-trust immunity to the merged professional football leagues. While owners invariably cited financial difficulties as the primary factor in such moves, many fans bitterly disputed these contentions, especially in Cleveland (the Rams and the Browns), Baltimore (the Colts), Houston (the Oilers), and St. Louis (the Cardinals), each of which eventually received teams some years after their original franchises left (the Browns, another Browns, Ravens, Texans, and Rams, respectively). Notably, Los Angeles, the second-largest media market in the United States, has not had an NFL team since 1994 after both the Raiders and the Rams relocated elsewhere. As of 2012, two proposals, Farmers Field in downtown Los Angeles and Los Angeles Stadium in the city of Industry, are in various stages of development; the Industry site is the furthest along and awaits the relocation of an NFL franchise.
While baseball is known as "America's national pastime," football is the most popular sport in the United States. According to the Harris Poll, professional football moved ahead of baseball as the fans' favorite in 1965, during the emergence of the NFL's challenger, the American Football League, as a major professional football league. Football has remained America's favorite sport ever since. In a Harris Poll conducted in 2008, the NFL was the favorite sport of as many people (30%) as the combined total of the next three professional sports – baseball (15%), auto racing (10%), and hockey (5%). Additionally, football's American television viewership ratings now surpass those of other sports, although football season comprises far fewer games than the seasons of other sports.
However, the Harris Poll only allows one unaided selection of a "favorite sport." Other studies and polls such as the ESPN Sports Poll and the studies released by the Associated Press (AP) and conducted by Sports Marketing Group (SMG) from 1988 to 2004, show far higher levels of popularity for NFL football since they list from thirty to over 100 sports that each respondent must rate. According to the AP, the SMG polls from 1988 to 2004 show NFL football to be the most popular spectator sport in America. The AP stated that "In the most detailed survey ever of America's sports tastes" researching "114 spectator sports they might attend, follow on television or radio or read about in newspapers or magazines, the NFL topped all sports with 39 percent of Americans saying they loved it or considered it one of their favorites." In a 2003 study conducted by SMG and released by the AP, the NFL was loved or liked a lot by 42.8% of Americans over 18.
The NFL has the highest per-game attendance of any domestic professional sports league in the world. The NFL's overall attendance, however, is only approximately 20 percent of Major League Baseball, because of the latter's longer schedule (162-game scheduled regular season).
A 2007 Turnkey Sports & Entertainment's Team Brand Index for "team loyalty" ranked NFL teams in twelve of the top twenty-five spots out of 122 total between the four major sports leagues. The Pittsburgh Steelers and their fanbase had the top spot, while the New England Patriots, and Indianapolis Colts had the following two spots, followed by the New Orleans Saints at number seven and the Green Bay Packers and their fanbase ranked at number ten. The Arizona Cardinals finished last in the entire survey of 122 teams, though the survey was taken before the team's appearance against the Steelers in Super Bowl XLIII.
