More exposure boosts the profile of the sport It gives more cash to upgrade resources, coaching, or facilities. Provides financial certainty to the sport for a set amount of time It attracts the world's finest players to that sport. Gives something tangible to the millions who support sport without playing it. The first three advantages are probably obvious but the last one not so much. Millions of people around the world support sport without playing it. That's because sports such as cricket, rugby, soccer, and tennis have huge fan bases who enjoy the sport regardless of who plays or doesn't play. The same can't be said for other sports such as boxing, wrestling, and MMA which involve many more physical contacts than those five sports just mentioned. The main advantage of commercialising sport is money. Sports marketing is a multi-billion-dollar industry and growing. As soon as you become successful at a non-profit level, others will want in on the action. So, if you're a coach or a team manager at an international level, you'll need to think carefully about how you want to develop your career. There are two ways to go about this: You can join a professional club and work your way up through their system, or you can start your own team and try to make them successful enough to attract sponsors.
