I will be honest with you - I have never liked the Title of the Championship Series of the United States of Americas Major League Baseball.
but a while back I was told a story about how the name came about.
it goes like this - back in the 1800's the sponsor of the National Baseball Competition was a newspaper called the World, so the Title of the Competition was the World Series.
I honestly thought that was true, it made sense.
But Wikipedia has other ideas
International impact, and explanation of the term "World" Series
The title of this championship may seem odd to some readers from countries where baseball is not a major sport (or even where it is), because the "World" Series is confined to the champions of two baseball leagues that currently operate only in the United States and Canada.
The explanation is that when the term "World's Championship Series" was first used in the 1880s, baseball at a highly-skilled level was almost exclusively confined to North America, especially the United States. Thus it was understood that the winner of the major league championship was the best baseball team in the world. The title of this event was soon shortened to "World's Series" and later to "World Series". "The Series", by itself, capitalized, is understood to mean "The World Series", in the appropriate context.
The United States, Canada and Mexico (Liga Mexicana de Beisbol, established 1925) continued to be the only professional baseball countries until some decades into the 20th century. The first Japanese professional baseball efforts began in 1920. The current Japanese leagues date from the late 1940s. Various Latin American leagues also formed around that time.
By the 1990s, baseball was played at a highly skilled level in many countries, resulting in a strong international flavor to the Series, as many of the best players from the Pacific Rim, Latin America, the Caribbean, and elsewhere now play on Major League rosters. The notable exception is Cuban nationals, due to the political situation between the USA and Cuba (despite that barrier, over the years a number of Cuba's finest ballplayers have defected to the United States to play in the American professional leagues). Players from the Japanese Leagues also have a more difficult time coming to the Major Leagues because they must first play 10 years in Japan before becoming free agents. Reaching the high-income Major Leagues tends to be the goal of many of the best players around the world. MORE
At the end of the day - whether you like the title or not. Its a great sporting event.
