Major League Soccer (MLS) is a mens professional soccer league, sanctioned by U.S. Soccer, that represents the sports highest level in both the United States and Canada. MLS constitutes one of the major professional sports leagues of the United States and Canada. The league is composed of 22 teams—19 in the U.S. and 3 in Canada. The MLS regular season runs from March to October, with each team playing 34 games; the team with the best record is awarded the Supporters' Shield. The postseason includes twelve teams competing in the MLS Cup Playoffs through November and December, culminating in the championship game, the MLS Cup. MLS teams also play in other domestic competitions against teams from other divisions in the U.S. Open Cup and in the Canadian Championship. MLS teams also compete against continental rivals in the CONCACAF Champions League. Major League Soccer was founded in 1993 as part of the United States' successful bid to host the 1994 FIFA World Cup. The first season took place in 1996 with ten teams. MLS experienced financial and operational struggles in its first few years: The league lost millions of dollars, teams played in mostly empty American football stadiums, and two teams folded in 2002. Since then, MLS has expanded to 22 teams, owners built soccer-specific stadiums, average MLS attendance exceeds that of the National Hockey League (NHL) and National Basketball Association (NBA), MLS secured national TV contracts, and the league is now profitable. Instead of operating as an association of independently owned teams, MLS is a single entity in which each team is owned and controlled by the leagues investors. The investor-operators control their teams as owners control teams in other leagues, and are commonly (but inaccurately) referred to as the teams owners. The league has a fixed membership, like most sports leagues in the United States and Canada, which makes it one of the worlds few soccer leagues that does not use promotion and relegation, a practice that is uncommon in the two countries. MLS headquarters is located in New York City.
