Why is it called the World Series in baseball?

Because the World Series only involves US teams (and one Canadian team), it’s no wonder that people often ask how the World Series got its name.

It’s called the World Series because when the first event took place in 1903, the US was the only place in the world with professional baseball games. Therefore, the winning team at that time would be the literal world champion. Now, baseball is an Olympic sport, and there are international baseball leagues.
