Sogou Pinyin is our self-developed Chinese Character Input Method software, whose vocabulary database is tied to the search queries database of Sogou search engine and thus can capture the latest trend of words used by Internet users. Since its launch in 2006, Sogou Pinyin has been well received by users. It continues to gain popularity and expand market share through superior product quality and effective marketing campaigns. As of December 31, 2008, Sogou Pinyin had been installed in over 50% of PC’s in China.
