Top Web Sites by Country - a #Visualization

via Information Geographies, we have a chloropleth of the most visited web-sites by country - weighted by that country's internet-using population.
The weighting is particularly useful, as it keeps mail.ru from taking over the top-spot due to the sheer size of Russia.
The key take-aways?

The supremacy of Google and Facebook over any other site on the Web is clearly apparent. We also see an interesting geographical continuity of these two “empires”. Google is the most visited website in most of Europe, North America, and Oceania. Facebook, in contrast, is the most visited website in most of the Middle East and North Africa, as well as much of the Spanish-speaking Americas. 

The situation is more complex in Asia, as local competitors have been able to resist the two large American empires. Baidu is well known as the most used search engine in China, which is currently home to the world’s largest Internet population at over half a billion users. At the same time, we see a puzzling fact that Baidu is also listed as the most visited website in South Korea (ahead of the popular South Korean search engine, Naver). We speculate that the raw data that we are using here are skewed. However, we may also be seeing the Baidu empire in the process of expanding beyond its traditional home territory.

Interestingly, pretty much everywhere, if Google isn't first, its second - truly quite the empire...
