Proprietary Search Engine—Sogou.com

Sogou, which means “Search Dog”, is Sohu’s proprietary search engine launched in August 2004. Sogou performs interactive searches of billions of Web pages using advanced algorithms. The user is taken through a fast and convenient interactive process to arrive at the most relevant selection of the integrated Website and page search results. On February 25, 2005, we launched our upgraded search engine Sogou 2.0 with an expanded breadth of one billion Chinese language indexed web pages, higher updating speed and shorter search time.

17173.com

STYLE="margin-top:6px;margin-bottom:0px">The Sohu games portal www.17173.com was launched in 2000 as the first online games portal in China and was acquired by Sohu in November 2003. 17173.com is a leading
online destination for game players seeking information on games and feedback from other players on the site’s message boards. With over 100 game zones and millions of registered users supported by alliances with over thousands of Internet

Website, building a game community and developing relationships with advertising clients in the online games industry.

Focus.cn

STYLE="margin-top:6px;margin-bottom:0px">Focus.cn is one of the leading real estate Websites in China. Focus.cn attracts many users who are homeowners with high incomes and real estate professionals. Launched in
1999, Focus.cn has developed into what we believe is one of the most influential Websites serving the Beijing market. The Focus.cn platform serves as a basis for regional expansion in other key urban areas where Internet penetration is highest in
China. As of December 31, 2007, the Website has successfully rolled out into 28 cities. Focus has also been enriching its content and has diversified from residential properties to commercial properties, as well as other auxiliary industries,
such as home decoration, furniture and fixtures.

Chinaren.com

SIZE="2">We acquired ChinaRen in October 2000. ChinaRen is the largest online youth community in China, with over eighty million registered users as of December 31, 2007. Schools and universities in China generally do not have alumni offices to
cater to the needs of former students to organize their classes into long-term communities. As in other Asian societies, Chinese people hold strong ties of friendship and loyalty with their fellow alumni, which form the basis of their personal and
professional relationship networks. ChinaRen has leveraged a critical mass of loyal users to create one of the leading online alumni networks in China.

SIZE="2">Go2Map.com

Go2Map is one of the leading online mapping services providers in China founded in 1999. Go2Map mapping information platform
enables online mapping services through different Internet/Intranet platforms, mobile phones, call centers and PDAs. Go2Map’s database covers points of interests in more than 307 cities across China, which has enabled it to develop multiple
business applications, including sales of software and map information resources. Go2Map also provides Web surfers a free online mapping inquiry system in large Chinese cities. We acquired Go2Map in May 2005 and Go2Map’s expertise in
professional location-based information had enhanced our search engine capabilities as well as online Website content.

Goodfeel.com.cn


Goodfeel is a leading WAP service provider in China, offering various WAP services including ring tone and picture downloads. Goodfeel.com was founded in November 2001
and was acquired by us in May 2004. Goodfeel has since been integrated with our WAP business. We believe it is important for Sohu to maintain a presence on the wireless side, and more specifically in WAP, in anticipation of the launch of the third
generation of mobile networks in China in the near future and the burgeoning market that it will bring.
