Baidu, China's version of Google, is set to face more intense competition with the merger of its third and fourth largest rivals.
Internet giant Tencent has announced its Soso search-related business will combine with Sohu's Sogou, according to a press release on Monday.
This was part of a deal which saw Tencent invest US$448 million in cash in Sogou, giving it a 36.5 percent stake, which could further increase to about 40 percent in future.
In the first half of 2013, Sohu's Sogou was ranked third with 8.83 percent of the market share ahead of Tencent's Soso with 3.45 percent, noted The Next Web. Market leader had a share of around 69 percent, with relative newcomer snatching 15 percent in second spot. Google had a share of 2.13 percent in fifth place.
"This partnership will immediately expand Sogou's market presence and significantly elevate its position in the highly competitive PC search market, and even more so in the rapidly evolvingmarket," said Charles Zhang, chairman and CEO of Sohu.
Tencent and Sogou have agreed to jointly develop, cross-promote and integrate their respective products and services, while collaborating in areas of search technology, user insights and data sharing. Sogou's leading products, including Sogou Pinyin and Sogou Search, will gain direct access to the massive user base of Tencent's online and mobile social communities.
The news is likely to quash the possibility thatfor US$1.4 billion as speculated in July.
