List of Major League Soccer seasons
Major League Soccer is the premier professional soccer league in the United States and Canada. As of 2016, it consists of 20 teams: 17 in the United States and 3 in Canada. The league has played since 1996. Each year, it plays a league which determines entry into the playoffs. The league is divided into two conferences, the Eastern Conference and Western Conference. In 2000 and 2001, there was also a Central Conference. The team with the overall best regular-season record is awarded the MLS Supporters' Shield, one of three major domestic trophies in North American soccer (the others being the national championships—the Lamar Hunt U.S. Open Cup or the Canadian Championship—and the primary trophy: the MLS Cup league championship). In 2010 and 2011, the league played as a double round robin, with each team playing each other team one home and away—creating a balanced schedule. With a prime number of teams beginning in 2012, the league has moved to an unbalanced schedule weighted towards a team's respective conference.
