Pedantic and off subject, but it's a long lived myth that our World Series was named for the New York World newspaper, which supposedly sponsored the earliest contests. In actuality, the name had a more benign and less domineering beginning.
"This usage can be traced through the annual baseball guides. Spalding's Base Ball Guide for 1887 reported the results of the 1886 postseason series between Chicago, champions of the National League, and St. Louis, champions of the American Association, under the heading "The World's Championship." As the editor noted, the two leagues "both entitle their championship contests each season as those for the base ball championship of the United States," so a more grandiose name was required to describe the postseason showdown between the two "champions of the United States."
"But the Spalding Guide -- which, after all, was published by one of the world's largest sporting goods companies, with a vested interest in bringing baseball to other lands -- had grander ambitions. By 1890, the Spalding Guide was explaining that "[t]he base ball championship of the United States necessarily includes that of the entire world, though the time will come when Australia will step in as a rival, and after that country will come Great Britain; but all that is for the future."

This didn't happen, but the name "World's Championship Series" stuck...
