Brazil's government tourism authority Embratur took advantage of today's live World Cup draw to start targeting online videos at potential visitors to Brazil from key tourism markets.

Rio de Janeiro's shanty towns, its favelas, long stricken by poverty and violence, have a new boogeyman: Gentrification.

Shanghai is a city that connotes modernity and rapid economic development. Its inhabitants are known both within and without its confines as upwardly mobile, career-oriented, and financially minded.

If such a thing is possible, Shanghai today beckons even more powerfully than it did in the past, playing a critical role among the great cities of the world beyond anything that could have been imagined. Shanghai’s future shines brilliantly, given its own dynamic economy and the larger Chinese economy of which it is a critical part. However, as China’s most prosperous city, Shanghai should not be afraid to strike out on its own or, more accurately, to define the terms of its development in its own way and according to its own history and understanding of its future.
