American football in the United States

• 1. Introduction

  ›

  American football in the United States is more than a sport. It is a national institution measured in stadiums that dwarf most of the world's largest venues, in leagues that generate more revenue than any other sports organization on earth, and in a culture that weaves itself into Friday nights at high schools, Saturdays on college campuses, and Sundays across a nation. Eight college stadiums alone seat more than 100,000 fans and typically sell out every game. The National Football League draws higher average attendance than any sports league in the world. So how did one game come to fill this space in American life? Who governs it, who plays it, and what does it look like from the professional summit down to the amateur fields where working men play on weekends? Those are the questions worth chasing.

• 2. The NFL at the Top

  ›

  The 32-team National Football League stands today as the only major professional American football league operating in the United States. That singular status was not inevitable. Over several decades, numerous efforts arose to build a second major-league competitor. Most failed within a few years. The All-America Football Conference and the 1960s American Football League were the rare exceptions, each surviving long enough to merge with the NFL rather than fold outright. The NFL's dominance in revenue and average attendance has no peer among any sports league in the world.

  The Super Bowl serves as the NFL's championship game, the culmination of each season. Stadium capacity figures across the league's 32 franchises tell their own story. The Dallas Cowboys regularly host over 90,000 fans per game, with a footnote in the data acknowledging that the figure drops to roughly 80,000 if you exclude people watching on screens at the stadium's party decks. The Green Bay Packers and New York Giants each fill venues approaching or exceeding 77,000 seats. League-wide, average attendance across seasons from 2016 to 2024 held remarkably steady in the mid-60,000s, rising to an average of just under 69,500 in 2025.

  The NFL has not operated developmental minor leagues since NFL Europe folded in 2007. Independent leagues exist, but they carry no formal affiliation with NFL franchises and operate outside the league's oversight.

• 3. The Spring Leagues and Indoor Game

  ›

  Below the NFL, a layer of professional football has been assembled, collapsed, and rebuilt multiple times. The eight-team United Football League now serves as the predominant professional spring football league. Its origins run through two separate predecessors: the XFL, originally founded in 2020, and the USFL, which launched in 2022. Both began as independent eight-team leagues before agreeing to merge with each other.

  The names they carried came with history attached. The USFL took its name from a major professional league that operated in the 1980s; securing the right to use it required reaching a settlement with that earlier league's remaining rightsholders. The XFL was itself a revival of a 2001 league bearing the same name and created by the same founder, Vince McMahon, who sold the league and its brand before the 2020 season could be completed. When the two conferences merged, they kept the XFL and USFL names as conference labels until Mike Repole took over the league and eliminated both brands during the 2025 offseason. A third-tier outdoor league, the Continental Football League, is slated to begin play in 2026.

  Indoor football occupies its own corner of the professional and semi-professional landscape. These leagues play at hockey-sized arenas, on fields half the width and length of a standard football field, under rules adjusted accordingly. The Arena Football League launched in 1987 and remained the most prominent indoor league for decades. Operational problems following its 2008 bankruptcy accelerated a slow collapse; teams left, and the AFL folded entirely in 2019. A revival attempt in 2024 fell apart within weeks of its opening season. The surviving teams reorganized, abandoned the AFL name, and rebranded as Arena Football One. The Indoor Football League, now the largest and oldest operating indoor league, spans 13 teams from Ohio to California, mostly in markets that already host major or high-minor professional sports franchises.

• 4. College Football's Scale

  ›

  Michigan Stadium at the University of Michigan is one of eight college football venues that seat more than 100,000 fans, and in 2025 the Michigan Wolverines drew the highest average home attendance of any college football program in the country. The other seven stadiums in that tier belong to Penn State, Ohio State, Texas A&M, the University of Tennessee, LSU, Alabama, and the University of Texas at Austin. They typically sell out.

  The National Collegiate Athletic Association governs college football, organizing teams across four divisions: the Football Bowl Subdivision, the Football Championship Subdivision, Division II, and Division III. The FBS and FCS were formerly called Divisions I-A and I-AA. Within the FBS, an informal further division separates "major conferences," historically called the Power Five and now reduced to four with the breakup of the Pac-12 Conference, from the "Group of Five" mid-major conferences. In practice, national championship contention has been limited to major-conference programs, though mid-majors gained a more realistic path to major bowls after the introduction of the BCS National Championship Game.

  The FCS operates a full multiple-round playoff. Three FCS conferences do not participate: the Ivy League, which prohibits postseason play; and the historically Black SWAC and MEAC, which instead meet each other in their own bowl. Division III programs offer no athletic scholarships. Two FCS leagues, the Ivy League and the Pioneer Football League, also do not offer football scholarships, though Pioneer Football League members do provide scholarships in other sports.

  The weekly autumn college football calendar carries cultural weight beyond the games themselves. Marching bands, homecoming ceremonies, tailgate gatherings, and cheerleaders combine to make the Saturday ritual a significant part of campus and regional identity. Football also drives substantial revenue to athletic programs at both public and private institutions. Top players exit college and enter the NFL Draft, seeking contracts with professional teams.

  The NCAA is not the only body. The NAIA oversees smaller private colleges, mostly in the Midwest. Community college football falls to the NJCAA in 46 contiguous states; California operates its community college athletics through its own body, the CCCAA, outside the NJCAA's reach. Ten northeastern colleges compete in the Collegiate Sprint Football League, where players must weigh no more than 178 lb to be eligible. A second sprint league, the Midwest Sprint Football League, launched in 2021.

• 5. High Schools, Amateurs, and Women's Football

  ›

  Most high schools in the United States field football teams. Top programs regularly fill stadiums holding more than 10,000 fans and can afford artificial playing surfaces. Teams generally compete within their own state, with exceptions for schools near a state border and occasional nationally-ranked matchups arranged for television. Public high school football in most states falls under the National Federation of State High School Associations.

  For rural schools whose student populations cannot support a full eleven-man roster, the NFHS sanctions nine-man football, which has found a strong following in the upper Midwest. Six-man football is the traditional reduced-roster format in parts of Texas, while eight-man football is the most common abbreviated format across most other states.

  Adult amateur football occupies the level below formal minor leagues. Commonly called "working man's football," the amateur game draws players who hold regular jobs and compete on weekends without pay. The rules typically blend NFL and NCAA standards. Regional leagues have operated across the country for decades; the Eastern Football League, for instance, traces its first season to 1961, and the Empire Football League to 1969. The Mason-Dixon Football League has been running since 1978.

  Women's professional football has its own long history in the United States. The Women's Professional Football League ran from 1965 to 1973. Patricia Palinkas became the first woman to play in the Atlantic Coast Football League in 1970, serving as the holder for the Orlando Panthers. In 2010, Katie Hnida took the field as the kicker for the Fort Wayne FireHawks in the Continental Indoor Football League. The current major women's league is the Women's Football Alliance, which began play in 2009 after absorbing teams from two dissolved predecessors: the National Women's Football Association and the Women's Professional Football League.

• 6. Governing Bodies and the National Team

  ›

  No single national body holds authority over all of American football in the United States. USA Football serves as the domestic governing body, while the International Federation of American Football, known by its acronym IFAF, governs the sport at a global level.

  USA Football assembles a national team for the IFAF World Championship, held every four years. For the first two championships, in 1999 and 2003, the United States chose not to field a team due to concerns about competitive balance. The 2007 team was composed entirely of amateur players who had graduated from college that spring, drawn from a diverse range of smaller and larger schools. The eligibility criteria for the 2011 squad were broadened to allow some professional players, though these were primarily unemployed, lower-level, or minor-league athletes; no NFL players or active college stars were included. Both the 2007 and 2011 teams won their respective world championships.
