The Financial Times has a profile on Naver's dominance in the Korean search engine marketplace. The article mainly reviews the impressive traffic statistics and use of human editors to generate content for Naver:

Naver – based on the English word “navigator” – attracts about 16m unique users a day, generating a total of 1bn page views.

This means that it commands more than 77 per cent of the internet search market in Korea – streets ahead of its local and international rivals.

It also mentions that Naver's Japanese search engine will launch in the first quarter of 2008.
