No matter where we live, we often have a distorted idea of how famous or popular our favorite celebrities, sports teams, musicians, actors, etc. are outside our own social circles (never mind outside our home countries).
How do you determine the “most famous” ANYTHING? Is it a matter of “how many people in the world have ever heard of this, even if it sounds only vaguely familiar”? Or do we require that people actually know and care a great deal about it?
On one hand, there are FAR more people in both India and China than in the United States. So, a national icon in either of those countries is known and recognized by far more people than even a major American celebrity. But if that person is known ONLY in India or China, can we really say that person is “the most famous person in the world”?
Now, there is no doubt that, internationally, soccer is far more popular than baseball, basketball or American football. There are FAR more people in the world who could name the starters for Manchester United than there are who could name the starters for the New York Yankees or the Dallas Cowboys.
On the other hand, many American athletes and teams are so associated with American pop culture, that billions of people have at LEAST a passing acquaintance with them, even if those people aren’t exactly sure who they are or what they do or how their sport works.
To THAT extent, some American sports teams are “famous,” perhaps more “famous” than soccer teams that have a far greater number of serious fans.
Even a kid in Mumbai who doesn’t know or care a bit about baseball may wear a New York Yankees cap, just because he thinks it looks cool. I’ve SEEN kids in Ireland wearing Dallas Cowboys jerseys, even though none of them could name a single player for that team.
So, hypothetically, lets say 2 billion people in this world are avid soccer fans and only 500 million are baseball fans (I’m making up these numbers, obviously). That would mean there are far more people who follow Manchester United and Real Madrid internationally than there are who follow the New York Yankees or Dallas Cowboys. But even people who coudn’t care less about American sports sort of know who the Yankees and Cowboys are. Hence, the Yankees or Cowboys Might be “more famous.” There are different types and different levels of fame here.
