If the company tours around the world, it's a world title... If a local indy fed were to advertise their title as a world title, I'd not take it serious. Since TNA does international business, I buy it being a world title......it's still worthless, but it's worthless worldwide at least.
I always thought that there would be some mileage on a heel losing a U.S. Title match in another country and then using the clause that it's the U.S. Title to get the decision reversed.. Same thing with the IC title, if it's defended on an island or something.
