Major League Baseball (MLB) is a professional baseball league and the highest level of organized baseball in the United States and Canada. One of the big four major leagues, MLB comprises 30 teams, divided equally between the National League (NL) and the American League (AL), with 29 in the United States and 1 in Canada. Formed in 1876 and 1901, respectively, the NL and AL cemented their cooperation with the National Agreement in 1903, making MLB the oldest major professional sports league in the world. They remained legally separate entities until 2000, when they merged into a single organization led by the Commissioner of Baseball.[3][7][16][17] MLB is headquartered in Midtown Manhattan.[7]
Baseball's first all-professional team, the Cincinnati Red Stockings, was founded in 1869. The first few decades of professional baseball saw rivalries between leagues, and players often jumped from one team or league to another. These practices were essentially ended by the National Agreement of 1903, in which AL and NL agreed to respect each other's player contracts, including the contentious reserve clause.
The period before 1920 was the dead-ball era, when home runs were rarely hit. Professional baseball was rocked by the Black Sox Scandal, a conspiracy to fix the 1919 World Series. Baseball survived the scandal, albeit with major changes in its governance as the relatively weak National Commission was replaced with a powerful Commissioner of Baseball with near-unlimited authority over the sport.
MLB rose in popularity in the decade following the Black Sox Scandal, and unlike major leagues in other sports it endured the Great Depression and World War II without any of its teams folding. Shortly after the war, Jackie Robinson broke baseball's color barrier.
Some teams moved to different cities in the 1950s and 1960s. The AL and NL added eight clubs in the 1960s: two in 1961, two in 1962, and four in 1969. Player discontent with established labor practices, especially the reserve clause, led to the organization of the Major League Baseball Players Association to collectively bargain with the owners, which in turn led to the introduction of free agency in baseball.
Modern stadiums with artificial turf surfaces began to change the game in the 1970s and 1980s. Home runs dominated the game during the 1990s. In the mid-2000s, media reports disclosed the use of anabolic steroids among MLB players; a 2006–07 investigation produced the Mitchell Report, which found that many players had used steroids and other performance-enhancing substances, including at least one player from each team.
Each team plays 162 games per season, with Opening Day traditionally held during the first week of April. Six teams in each league then advance to a four-round postseason tournament in October, culminating in the World Series, a best-of-seven championship series between the two league champions first played in 1903. The New York Yankees have the most championships with 27. The reigning champions are the Texas Rangers, who defeated the Arizona Diamondbacks in the 2023 World Series.
MLB is the second-wealthiest professional sports league by revenue in the world after the National Football League (NFL).[18][19][20] Baseball games are broadcast on television, radio, and the internet throughout North America and in several other countries. MLB has the highest total season attendance of any sports league in the world; in 2018, it drew more than 69.6 million spectators.[21]
MLB also oversees Minor League Baseball, which comprises lower-tier teams affiliated with the major league clubs, and the MLB Draft League, a hybrid amateur-professional showcase league. MLB and the World Baseball Softball Confederation jointly manage the international World Baseball Classic tournament.
Official MLB history dates to 1876, when the National League began play. According to research by MLB's official historian, John Thorn, the first run came on April 22 of that year – in the first game of the season, between the Boston Red Stockings, now the Braves, and the Philadelphia Athletics.
The strength of the American League grew as an increasing number of National League players opted for the higher salaries offered by the new association. Faced with the prospect of losing many of its best players, the NL chose peace and declared the AL its equal in 1903. This led to a new National Agreement and the birth of the World Series. The American and National Leagues were established as major leagues and all other associations comprised the minor leagues, which fell under the jurisdiction of the National Association of Professional Baseball Leagues.
