Final answer:
The World Series is named due to an early sponsorship with the New York World newspaper, and while it implies global participation, it is mainly a North American championship.
Step-by-step explanation:
The term World Series is historically significant and may appear to have an international connotation, but it is actually the championship series of Major League Baseball (MLB) in North America, primarily involving teams from the United States. The name originates from an early sponsorship deal with the New York World newspaper in the early 20th century. Despite the global name, the World Series has largely been contested by North American teams, with rare participation by teams from other countries.
