Mark Graham and Stefano De Sabbata for Information Geographies mapped the most visited site based on Alexa data. Countries are sized by Internet population. There aren't many surprises with Facebook and Google in the Americas and and Europe, but it gets more interesting when you look elsewhere.
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.
The remaining territories that have escaped being subsumed into the two big empires include Yahoo! Japan in Japan (in join venture with SoftBank) and Yahoo! in Taiwan (after the acquisition of Wretch). The Al-Watan Voice newspaper is the most visited website in the Palestinian Territories, the e-mail service Mail.ru is the most visited in Kazakhstan, the social network VK the most visited in Belarus, and the search engine Yandex the most visited in Russia.
