The two leagues merged in 2000 into a single organization led by the Commissioner of Baseball, after 100 years as separate legal entities.MLB constitutes one of the major professional sports leagues of the United States and Canada. It is composed of 30 teams — 29 in the United States and one in Canada. With the International Baseball Federation, MLB also manages the World Baseball Classic. MLB has the highest season attendance of any sports league in the world.MLB is governed by the Major League Baseball Constitution that has undergone several incarnations since 1875 with the most recent revisions being made in 2012. Under the direction of the Commissioner of Baseball (currently Bud Selig), Major League Baseball hires and maintains the sport's umpiring crews, and negotiates marketing, labor, and television contracts.Major League Baseball maintains a unique, controlling relationship over the sport, including most aspects of minor league baseball. This is due in large part to a 1922 U.S. Supreme Court ruling in Federal Baseball Club v. National League, which held that baseball is not interstate commerce and therefore not subject to federal antitrust law. This ruling has been weakened only slightly in subsequent years.Although there were several challenges to Major League Baseball's primacy in the sport between the 1870s and the Federal League in 1916, the last such challenge was the aborted Continental League in 1960.As of the 2013 season, Major League Baseball is divided into the American League (15 teams) and the National League (15 teams).Currently, each league is further subdivided into three divisions—labeled East, Central, and West. The three-division structure dates back to 1994, the first season after the National League expanded to 14 teams. From 1969 through 1993, each league consisted of an East and West division. Through 1996, the two leagues met on the field only during the World Series and the All-Star Game: in 1997, regular-season interleague play was introduced.In March 1995, two new franchises—the Arizona Diamondbacks and Tampa Bay Devil Rays—were awarded by Major League Baseball, to begin play in 1998. This addition would bring the total number of franchises to 30. In early 1997, Major League Baseball decided to assign one new team to each league: Tampa Bay joined the American League and Arizona joined the National League. The original plan was to have an odd number of teams in each league (15 per league, with 5 in each division). MLB also planned to introduce interleague play in 1997, but — with each league having an odd number of teams—interleague play would have had to be used throughout the entire season, to allow every team to play every day. It was unclear, though, if interleague play would continue after the 1998 season, as it had to be approved by the players' union. For this and other reasons, it was decided that both leagues should continue to have an even number of teams; one existing club would have to switch leagues. The Milwaukee Brewers agreed in November 1997 to move from the American League to the National League, thereby making the National League a 16-team league.
