All of the minor leagues are operated as independent businesses . Most are members of the umbrella organization known as Minor League Baseball (MiLB), which operates under the Commissioner of Baseball within the scope of organized baseball . Several leagues, known as independent baseball leagues, do not have any official links to Major League Baseball . </P> <P> Except for the Mexican League, teams in the organized minor leagues are generally independently owned and operated but are directly affiliated with one major league team through a standardized Player Development Contract (PDC). These leagues also go by the nicknames the "farm system," "farm club," or "farm team (s)" because of a joke passed around by major league players in the 1930s when St. Louis Cardinals general manager Branch Rickey formalized the system, and teams in small towns were "growing players down on the farm like corn ." </P>
