Vincenzo Cosenza has been tracking various social networks’ popularity throughout the world, and he just posted a December 2010 map - based on data by Alexa and Google Trends for Websites - showing just how prominent Facebook has become throughout the world.
A comparison between this new map and one from June 2009 reveals that Facebook - consistently the top social network in countries like the U.S., Canada and Australia - is growing even more popular in the international sphere. Based on Cosenza’s findings, it looks like Facebook has replaced Orkut, once in the top spot, as the number one social network in India. And the site has also gained ground in South America and Europe.
There are some instances where other social networks have maintained their popularity; Russia is still dominated by V. Kontakte, and Orkut maintains a strong foothold in Brazil. Meanwhile, QZone’s big in China.
According to Consenza’s findings, other social networks, while not in the top spot, are also starting to gain some traction in other countries. LinkedIn is in third place in Australia and Canada, and Twitter holds the same ranking in Germany and Italy.
