Twitter is planning a big move to the eighth largest city (by population) in the world.

According to a report from Reuters, Twitter is planning on opening up an office in Brazil’s biggest city, Sao Paulo.

“We believe our new office in Brazil will allow us to get closer to the users and show the value of our platform,” the company’s new country manager for Brazil, Guilherme Ribenboim, told Reuters. “Brazil has rather mature Internet and advertisement markets. Our audience is very big and active. We are going to try to monetize it.”

Twitter isn’t lying about their audience being big. Brazil is the social site’s second-biggest market in terms of total accounts and fifth when it comes to usage stats. The only other country with more Twitter accounts that Brazil is the United States.

Ribenboim is already talking about why Brazil presents such a good opportunity for Twitter. Not only will the move put them closer to one of their largest user bases, but upcoming world events like the World Cup (2014) and the Summer Olympics (2016) are taking place in Brazil.

And we know how popular Twitter can be during these sort of global events.

“It is already happening. We are talking (to advertisers) looking for opportunities, strategies,” said Ribenboim.

Brazil has seen Facebook use surge over the past year, and Google+ has also grown significantly in the country. Although Brazil is one of Twitter’s biggest locations, having operations there will make it easier for them to expand in the emerging market.
