The acquisition is Google’s first acquisition in Asia outside China and follows its 2003 acquisition of Blogger. In July this year, it acquired Russian online advertising company ZAO Begun for $140m, and in March it acquired online ad serving and management technology provider DoubleClick.

Acquiring Tatter and Company will allow us to enhance our online publishing tools in Korea, benefiting a large number of users who already depend on and enjoy Google and Tatter and Company’s products.
