Geez, its because most of these championship series were started back in the early 1900s. To draw people in, they had to advertise somehow, with something like "Come see the best baseball teams play for the championship of the world!!!" People back then didn't really care about being PC, so it worked. The titles just stuck, and so we still play the World Series every October, which is almost always two American teams.
I look forward to having a true World Series of baseball someday, with teams from all over the world (N America, Central America, S. America, Japan, China, Europe, etc). Some people say the North American teams would have a huge advantage, but I disagree. About half of the players in the major leagues were born outside the US, so it could definitely be an even series.
