Argentina's Carlos Monzon attained global fame fighting mostly in Europe, could Sergio Martinez do that too?

At the moment and for many years the way to attain worldwide fame has been to fight in America. There has long been a saying: If you haven't done it in America you Haven't done it. Look at Joe Calzaghe, he was undefeated world super middleweight champion for 11 years and a great fighter, he only started to get a fraction of recognition when he crossed the pond to fight Hopkins and Jones. There is a great tradition, particularly among British fighters to cross the pond to attain fame: fighters such as Ted "Kid" Lewis, Jack "Kid" Berg, Jimmy Wilde, Jim Driscoll, Freddie Welsh, Ken Buchanan and Nigel Benn all went to America, if they had stayed put they probably wouldn't be as well known as they are now. America is such a large part of the English speaking world and of course it has a lot of money. It also has such boxing Mecca's as Madison Square Garden and Caesars Palace. Carlos Monzon did attain global fame by fighting in Argentina and Europe but he is one of the few. However I believe that is starting to change, in the last ten years or so Europeans have really become a major force in world boxing. The heavyweight division which at one time was the most important in boxing is dominated by Europeans and now they are starting to take over the middleweight division with the likes of Sturm, Pirog and Golovkin all holding world titles. So in answer to your question, at the moment no, I don't think you can attain global fame by fighting mostly in Europe, however soon you might well be able to.
