HISTORY

Major League Baseball, or MLB, is composed of 30 teams — 29 in the United States and 1 in Canada. With the International Baseball Federation, MLB also manages the World Baseball Classic. With an average attendance of 30,352 people per game, Major League Baseball has the fifth highest average attendance of any sports league behind the NFL, Bundesliga, AFL, and Premier League.

As of the 2012 season, Major League Baseball is divided into the American League (14 teams) and the National League (16 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.
