Nice article. it gave me a better idea of how Brazil has been seen abroad. It says lot of names that i know of and had no ideia that was doing so much.
About the companies using the sponsrships to promote their brands is indeed a problem, the Lei Rouanet (Rouanet's law) is still young and its developing. One good thing I see in this situation is that Brazil is a country that suffers too much with political corruption, and in this case we can feel that the money is going to where it should. We see results.
