Facebook use gained a lot of momentum in Brazil last year, according to new data from comScore. Brazil has been known to be one market where Google’s social network Orkut has actually been successful. Now, Facebook is bigger there too.

According to comScore, Brazil was one of only seven markets where Facebook didn’t dominate the social media channel, as of October. Other markets included: China, Japan, South Korea, Vietnam, Poland and Russia.

“Facebook’s rapid ascent in the Brazilian market has certainly been one of the most interesting stories to develop during the course of 2011,” said Alex Banks, comScore managing director for Brazil. “Brazil has always been a particularly social market and currently owns the fifth largest social networking population in the world. But despite the cultural affinity for social media, Facebook adoption had traditionally lagged in the market. That has all changed in the past year, during which the site has tripled in audience size as engagement has grown sevenfold to assume the leadership position in the market.”
