Europeans, North Americans and Antipodeans are far too greedy, think about the Asians, Africans and oil rich nations whose citizens are clearly the biggest fans in the world. There are so many of them on here posting day in day out, the fact Luanda and Kinshasa haven't ATP/WTA events is beyond me, its clearly where tennis is at these days.
I mean the WTA is clearly more up to date than the ITF, the ITF still host the slams in NYC, London, Paris and Melbourne. Clearly Beijing, Kinshasa, Florianopolis and Baku would be better locations. These are the "emerging markets" after all.
