La primera vez que se disputó una Serie Mundial de béisbol fue en el naciente siglo XX, específicamente en el año 1903. En aquella oportunidad, los Boston Americans (hoy en día los Red Sox) vencieron a los Pittsburgh Pirates en una serie al mejor de nueve partidos.
Esta representó la primera Serie Mundial de la era moderna del béisbol y continúa como tradición hasta hoy día. A lo largo de todos estos años, 25 diferentes franquicias han logrado alzar el título, siendo los New York Yankees los ganadores por excelencia del trofeo de los banderines.
En total, los Mulos del Bronx han alcanzado 27 campeonatos, seguidos por los St. Louis Cardinals con 11. Boston, junto a los Oakland Athletics, completan el podio con nueve cada uno. Desde aquel año hasta la actualidad se han disputado 119 finales (en 1904 ni en 1994 se jugó).
