Facebook is the McDonald’s of Social Networking. With more than 650 million active users, the social media site has become the choice of online connection around the world. (The U.S. is increasingly saying “I’m Lovin’ It”: more than 42% of Americans have a Facebook account.)

So, how has Facebook spread?

Vincenzo Cosenza has given us a new edition of the World Map of Social Networks, showing the most popular social networks by country, according to Alexa & Google Trends for Websites traffic data* (June 2011).

Below you will find an infographic poster of all changes since June 2009. You can also see an animated version of all his maps.

Cosenza writes:

Facebook is slowing gaining users around the world (almost 700 millions) establishing its leadership in 119 out of 134 countries analyzed (in this edition I’ve added Ethiopia and Tanzania).
Since December 2010 Zuck’s creature has conquered Iran and Syria, although struggling against censorship. Europe has now became the largest continent on Facebook with 205 million users (Facebook Ads Platform).

Probably Netherlands and Brazil will be the next countries to surrender. According to Alexa Facebook is already the leader there, but Google Trends shows a different picture (I will change my map when the two sources will say the same).

Here’s the current social media landscape:

Cliff Kuang, editor of Fast Company Design notes:

If you look closely, you’ll notice that all of these were bordered by other countries where Facebook already dominated. It’s probably a safe assumption to say that friends reaching across these geographic borders helped the network spread: Americans reached out to friends in Mexico, Nigerians reached out to Cameroonians, and Burmese connected with friends in Cambodia and Vietnam. (If you watched David Fincher’s Facebook film, The Social Network, this dynamic was mentioned, in the scene where Zuckerberg tells Shawn Parker how he rolled over non-compliant campuses by opening Facebook up to every college around it.)
