The early years of the NL were tumultuous, with threats from rival leagues and a rebellion by players against the hated "reserve clause", which restricted the free movement of players between clubs. Competitor leagues formed regularly and also disbanded regularly. The most successful was the American Association (1882–1891), sometimes called the "beer and whiskey league" for its tolerance of the sale of alcoholic beverages to spectators. For several years, the NL and American Association champions met in a postseason championship series—the first attempt at a World Series . The two leagues merged in 1892 as a single 12-team NL, but the NL dropped four teams after the 1899 season. This led to the formation of the American League in 1901 under AL president Ban Johnson , and the resulting bidding war for players led to widespread contract-breaking and legal disputes.
Until 1965  (when Major League Baseball made its first ever, league-wide regular-season network television deal with ABC), there was no league-wide national television package for regular season Major League Baseball games. As a result, teams, if they so desired, could sell the rights to the networks. Also prior to 1965, regular season Major League Baseball telecasts broadcast by networks had to be blacked-out in cities with league franchises. More to the point, by around the year prior, thanks to expansion (in 1960 and 1961 ), regular season MLB games shown on network television were blacked out in most major markets. However, the network Games of the Week , up until the late 1980s, still could not be seen in the two cities whose local teams were playing in each respective game.
