Italian PR professional and former Microsoft Italy marketer Vincenzo Cosenza sent us an interesting visualization today. Below is a map of the world, showing the most popular social networks by country. The map was built using Alexa and Google Trends for Website traffic data in June 2009 and we think it shows some interesting trends. After all, our world is becoming smaller and it's good to know what services our friends on the other side of the globe are using to connect with each other.

Top 3 Social Networking Sites by Country:

Australia: Facebook, MySpace, Twitter

Canada: Facebook, MySpace, Flickr

India: Facebook, Orkut, Hi5 (Twitter is a close fourth)

France: Facebook, Skyrock, MySpace,

China: QQ, Xiaonei, 51

Germany: Facebook, StudiVZ, MySpace

Italy: Facebook, Netlog, Badoo

Russia: V Kontakte, Odnoklassniki, LiveJournal

Spain: Facebook, Tuenti, Fotolog

United Kingdom: Facebook, Bebo, MySpace

United States: Facebook, MySpace, Twitter

Patterns:

Cosenza also noticed some visible patterns that are worth sharing. I've added my own notes in parenthesis:

- Facebook has almost colonized Europe and it's extending its domination with more than 200 millions users
- QQ, leader in China, is the largest social network of the world (300 million active accounts)
- MySpace lost its leadership everywhere (except in Guam)
- V Kontakte is the most popular in Russian territories (looks a lot like Facebook)
- Orkut is strong in India and Brazil (this one was a little scary because it already knew my name)
- Hi5 is still leading in Peru, Colombia, Ecuador and other scattered countries such as Portugal, Mongolia, Romania (Hi5 is a San Francisco based Company)
- Odnoklassniki is strong in some former territories of the Soviet Union
- Maktoob is the most important Arab community/portal
