Major League Baseball
Major League Baseball (MLB) is a professional baseball organization that constitutes one of the four major professional sports leagues in North America. MLB teams play in the American League (AL) and National League (NL), which operated as separate legal entities from 1901 and 1876 respectively. In 2000, the leagues merged into a single organization led by the Commissioner of Baseball. The organization oversees minor-league baseball leagues, which operate about 240 teams affiliated with the major-league clubs. With the International Baseball Federation, the league also manages the international World Baseball Classic tournament.
Baseball's first professional team was founded in Cincinnati in 1869. The first few decades of professional baseball were characterized by rivalries between leagues and by players who often jumped from one team or league to another. The period before 1920 in baseball was known as the dead-ball era; players rarely hit home runs during this time. Baseball survived a game-throwing incident known as the Black Sox Scandal in the 1919 World Series. Baseball rose in popularity in the 1920s, and survived potential downturns during the Great Depression and World War II. Shortly after the war, baseball's color barrier was broken by Jackie Robinson.
Chewing tobacco is a type of smokeless tobacco product consumed by placing a portion of the tobacco between the cheek and gum or upper lip teeth and chewing. Unlike dipping tobacco, it is not ground and must be manually crushed with the teeth to release flavor and nicotine. Unwanted juices are then expectorated (spat).
Chewing tobacco is typically manufactured as several varieties of product – most often as loose leaf (or scrap), pellets (tobacco "bites" or "bits"), and "plug" (a form of loose leaf tobacco condensed with a binding sweetener). Nearly all modern chewing tobaccos are produced via a process of leaf curing, cutting, fermentation and processing or sweetening. Historically, many American chewing tobacco brands (which were popular during the American Civil War era) were made with cigar clippings.
