Major professional sports leagues in the United States and Canada

Major League Baseball

Major League Baseball is the oldest major professional sports league in North America and the highest level of baseball competition in the United States and Canada. It originated from two separate leagues: the National League, founded in 1876, and the American League, founded in 1901. The champions of these two leagues first met in the World Series in 1903, though the 1904 series was cancelled when one champion refused to play. The leagues formally merged their administrative structures in 2000, though they have shared a single commissioner since 1920. MLB currently consists of 30 teams, with 29 located in the United States and one, the Toronto Blue Jays, in Canada. The league traditionally draws the largest total annual attendance of any sports league in the world, maintaining its status as a foundational part of American and Canadian sports culture.

The business operations of MLB are vast, with significant revenue generated from national television contracts and local broadcast deals. For the 2026 to 2028 period, MLB's national media rights are held by Fox, Turner, ESPN, NBC, Netflix, and Apple TV, generating approximately $2 billion annually. Individual teams also negotiate lucrative local broadcast contracts, with some clubs like the New York Yankees owning stakes in their regional sports networks. The league launched its own dedicated television channel, the MLB Network, in 2009.

National Basketball Association

The National Basketball Association is widely regarded as the premier professional basketball league in the world and is the youngest of the "Big Four" North American leagues. It was formed in 1949 through the merger of the Basketball Association of America (BAA) and the National Basketball League (NBL), though it recognizes the BAA's 1946 founding date. The league later expanded by absorbing four teams from the rival American Basketball Association in 1976. The NBA currently has 30 teams, with 29 in the United States and one, the Toronto Raptors, in Canada. The league enjoys massive global popularity, and as of 2022 it led the NFL, NHL, and MLB in worldwide desktop web traffic, which demonstrates its international appeal.

Television revenue is a major pillar of the NBA's economic strength. A new media rights deal took effect for the 2025-26 season, running through 2035-36 with partners ABC/ESPN, NBC, Peacock, and Amazon. This agreement is expected to generate total annual revenues of $6.9 billion, with roughly $6.7 billion allocated to the NBA and $200 million to the WNBA. This represents a dramatic increase from the previous deal with ABC/ESPN and TNT, which brought in $2.7 billion annually from 2016-17 to 2024-25. The NBA also operates its own network, NBA TV, launched in the United States in 1999 and in Canada in 2001. The league's regular season runs from October to April, with the playoffs extending into June.

National Football League

The National Football League is the preeminent professional American football league and the most popular sports league in the United States by television ratings and merchandising. It was founded in 1920 as the American Professional Football Association, changing to its current name in 1922. The league grew through absorbing elements of the All-America Football Conference in 1949 and merging with the American Football League in 1970. The NFL consists of 32 teams, all located in the United States, making it the only "Big Four" league without a Canadian franchise. Its championship game, the Super Bowl, is consistently the most-watched annual television event in the U.S., with Super Bowl LIX setting a viewership record.

The NFL generates the largest television revenues of any sports league. Its contracts with Amazon, CBS, ESPN, Fox, NBC, and DirecTV for the 2023 through 2033 seasons earn the league roughly $9 billion annually. Unlike other major leagues, NFL teams do not negotiate local broadcast contracts for regular season games due to the once-a-week schedule, though they can arrange deals for preseason contests. The league launched the NFL Network in 2003. The NFL season is comparatively short, with a preseason in August, a 17-game regular season from September to early January, and playoffs culminating in the Super Bowl in February. The league also plays a limited number of international games annually in stadiums in the United Kingdom, Germany, Mexico, and other countries.

National Hockey League

The National Hockey League is recognized as the world's premier professional ice hockey league and is the only "Big Four" league to have been founded in Canada, established in 1917 as a successor to the National Hockey Association. The league partially absorbed the rival World Hockey Association in 1979. It currently has 32 teams, with 25 in the United States and 7 in Canada, giving it more Canadian franchises than MLB, the NBA, and MLS combined. The NHL is the most popular sports league in Canada and has a strong following in the northern and northeastern United States, with expansion into sunbelt markets like Las Vegas and Seattle in recent decades.

The NHL's media rights are split between the United States and Canada. Its U.S. television deal with ABC/ESPN and Turner Sports runs from the 2021-22 season through 2027-28, reportedly worth about $625 million annually. In April 2025, the league announced a new 12-year Canadian rights agreement with Rogers Sportsnet worth C$11 billion (approximately US$7.7 billion), effective from the 2026-27 season through 2037-38. This replaced a previous deal that paid $433 million annually. The league operates the NHL Network in the United States, launched in 2007, while its Canadian network was shut down before the 2015-16 season. The NHL regular season runs from October to April, with the Stanley Cup playoffs concluding in June.

Major League Soccer and Canadian Football League

Major League Soccer and the Canadian Football League are two other major professional leagues with distinct profiles and fan bases. MLS is the top-level men's professional soccer league in the United States and also includes three Canadian teams. It was established in 1996 as a condition for the United States hosting the 1994 FIFA World Cup. The league has grown significantly, particularly after the 2007 adoption of the Designated Player Rule that allowed for signing international stars. As of the 2026 season, MLS has 30 teams. The CFL is the premier league for Canadian football, organized in 1956 from two older regional unions. It consists of nine teams, all based in Canada, and awards the historic Grey Cup championship each November.

The media landscapes for these leagues differ markedly. MLS's primary broadcast partner is Apple, which paid a reported $2.5 billion for exclusive worldwide streaming rights from 2023 to 2032 via MLS Season Pass. Linear television rights in the U.S. are held by Fox Sports, and in Canada by TSN and RDS. The CFL's main television deal is with TSN in Canada, paying at least $50 million annually through 2026, with a new agreement set for 2027 with TSN and DAZN worth $83 million per year. In the United States, a limited number of CFL games are broadcast on CBS Sports Network for about $1 million annually.

• MLS Teams: 30 teams (27 U.S., 3 Canada) as of 2026.
• CFL Teams: 9 teams, all in Canada.
• MLS Key Rule: Designated Player Rule (2007) for star signings.
• CFL Championship: Grey Cup, awarded annually in November.
• MLS Attendance (2017): Average 22,112. Total over 8.2 million.
• CFL Attendance (2024): Average 22,795.

In terms of attendance, MLS reported an average of over 22,000 fans per game in 2017, with total attendance exceeding 8.2 million. By 2024, the CFL's average attendance was 22,795, showing a slow upward trend. MLS teams also participate in multiple external tournaments like the CONCACAF Champions Cup and Leagues Cup, while the CFL's level of play is generally considered on the second tier of professional football globally. The CFL has a longer established history and a slight advantage in player recruitment compared to second-tier American leagues such as the UFL.

League Structures and Seasons

All major professional sports leagues in the United States and Canada operate as closed leagues, meaning they maintain the same set of teams from season to season without the promotion and relegation systems common in other parts of the world. Expansion typically occurs through the addition of newly created franchises, though historical growth has also involved mergers with rival leagues, such as the NFL-AFL merger in 1970 or the NBA-ABA merger in 1976. The standard size for the "Big Four" leagues is between 30 and 32 teams, with most concentrated in the largest metropolitan areas. MLS has also reached 30 teams, while the CFL operates with 9 teams.

The seasonal calendars for these leagues are designed to minimize direct overlap and capitalize on different times of the year. The NFL's season is the shortest and culminates in the winter. MLB has the longest regular season, spanning from spring through fall. The NBA and NHL seasons largely overlap during the winter and spring months. The table below illustrates the typical seasonal structure for each league, though exact dates can vary from year to year.

This structured calendar ensures a nearly continuous cycle of major professional sports for fans throughout the year. The off-seasons are used for drafts, free agency, and training camps, maintaining year-round engagement. The timing of championships, like the Super Bowl in February and the World Series in October, has become ingrained in the cultural calendar of both nations. The CFL's Grey Cup in November is the highest-attended sporting event in Canada, concluding that league's unique autumn schedule.

Revenue and Television Contracts

The major professional sports leagues are economic powerhouses, with the "Big Four" consistently ranking among the top sports leagues in the world by revenue. The NFL, MLB, and NBA are typically in the top three globally, followed by the English Premier League and the NHL. These revenues are driven primarily by massive television and media rights contracts, ticket sales, merchandising, and sponsorship deals. The financial scale of these leagues dwarfs that of other sports organizations in North America, allowing for high player salaries and significant investment in facilities and operations. Television exposure is critical, with games broadcast on major U.S. networks like ABC, CBS, NBC, and Fox, all of which have long-standing relationships with these leagues.

In Canada, the NHL has a historic and lucrative partnership with the CBC that lasted from 1952 to 2026, and a new monumental deal with Rogers. The CFL was broadcast on the CBC from 1952 to 2008 and returned to CTV in 2024. Each league has also launched its own dedicated television network to provide additional coverage and content directly to fans. These networks include NBA TV, the NFL Network, the MLB Network, and the NHL Network in the United States. All of these networks remain in operation today except for the Canadian NHL Network, which was shut down shortly before the league's 2015-16 season.

• NFL TV Revenue: ~$9 billion annually (2023 to 2033 deals).
• NBA TV Revenue: ~$6.7 billion annually (2025-36 deal).
• MLB TV Revenue: ~$2 billion annually (2026-28 deals).
• NHL Canadian Rights: C$11 billion over 12 years (Rogers, 2026-38).
• MLS Streaming Rights: $2.5 billion (Apple, 2023 to 2032).
• CFL Canadian Rights (2027): $83 million annually (TSN/DAZN).

The structure of these deals varies. The NFL's contracts are the most valuable, encompassing multiple broadcast and streaming partners. The NBA's new agreement represents a massive increase, nearly tripling its previous annual income. MLB's revenue comes from a diverse set of traditional and streaming partners. The NHL's value in Canada is exceptionally high, as shown by the Rogers deal. MLS has bet heavily on a global streaming future with Apple, while the CFL's television income, though smaller, is vital to its stability and has seen recent growth. The CFL's upcoming 2027 deal with TSN and DAZN will pay $83 million per year, which is in line with inflation compared to its previous agreement.

Attendance and Venues

Attendance is a key measure of popularity and commercial success for professional sports leagues. All major leagues in the United States and Canada average at least 15,000 fans per game. The NFL leads in average per-game attendance, drawing massive crowds to its large stadiums, which typically seat between 60,000 and 100,000 spectators. MLB ballparks generally hold between 30,000 and 50,000 fans, and the league consistently draws the largest total annual attendance in the world due to its long schedule. The indoor arenas used by the NBA and NHL usually have capacities between 18,000 and 20,000 seats.

Venue usage often involves sharing between leagues, particularly in multi-purpose facilities. As of recent data, 11 arenas host both NBA and NHL teams, 5 stadiums host NFL and MLS teams, 2 host CFL and MLS teams, and 1 hosts MLB and MLS teams. While MLB and NFL teams frequently shared stadiums in the past, no current arrangements exist. The NFL also plays a limited number of games annually in international venues, including stadiums in England, Germany, and Mexico. MLS and CFL venues vary more widely in capacity, from about 20,000 to 60,000 spectators. The NFL and MLB also play a limited number of annual games in English Premier League stadiums, and the NFL plays games in stadiums of Germany's Bundesliga and other international leagues.

The following table shows average attendance figures for the major leagues. Each of the major professional leagues averages at least 15,000 fans in attendance per game as of 2024. The NFL has the largest stadiums on average in the world, with capacities ranging from just over 60,000 to almost 100,000 spectators. As of 2017, Major League Soccer had the fifth largest total attendance and the third largest average attendance among sports leagues in the United States and Canada. MLB consistently draws the largest total attendance of any sports league in the world.

These attendance figures are sustained by fan commitment. Many multi purpose venues host events in multiple leagues. These shared venues include five for the NFL and MLS, two for the CFL and MLS, one for MLB and MLS, and eleven for the NBA and NHL. MLB and NFL teams frequently shared stadiums in the past, although none currently do. The experience of attending a game is a significant part of the sports economy in cities across both countries.

What is the newest major professional sports league?

Among the major leagues, Major League Soccer is the newest, having begun play in 1996. Its creation was a requirement by FIFA for awarding the United States the right to host the 1994 World Cup. MLS was the first top-division outdoor soccer league in the U.S. since the original North American Soccer League operated from 1968 to 1984. Of the "Big Four" leagues, the National Basketball Association is the youngest, tracing its founding to the merger of predecessor leagues in 1949, though it uses the 1946 founding date of the Basketball Association of America.

How do promotion and relegation work in these leagues?

The major professional sports leagues in the United States and Canada do not use a promotion and relegation system. They are closed leagues, meaning the same set of teams compete from season to season. League expansion occurs through the addition of newly created franchises, as seen when the NHL added the Seattle Kraken or when MLS expands to new cities. Historically, growth has also come from mergers with rival leagues, such as the NFL's merger with the American Football League in 1970. This model provides franchise stability and is a fundamental difference from the open league systems common in soccer leagues throughout Europe and other regions.

Which league has the most valuable television contract?

The National Football League has the most valuable television contracts. Its agreements with Amazon, CBS, ESPN, Fox, NBC, and DirecTV for the 2023 through 2033 seasons earn the league roughly $9 billion annually. This dwarfs the contracts of other leagues. For comparison, the NBA's new deal starting in 2025-26 is expected to generate about $6.7 billion annually for the NBA itself, and MLB's national contracts for 2026-28 bring in approximately $2 billion per year. The NFL's massive media revenue is a key reason it is the wealthiest sports league in the world.

What is the Designated Player Rule in MLS?

The Designated Player Rule, often called the 'Beckham Rule,' is a Major League Soccer policy adopted in 2007 that allows each team to sign up to three players whose salaries exceed the league's normal salary cap. The rule was designed to enable MLS clubs to attract international star players, thereby increasing the league's quality and profile. Its adoption led to high-profile signings such as David Beckham, Thierry Henry, and more recently Lionel Messi. This rule has been a significant factor in the growth of MLS's popularity and competitive stature over the past two decades.
