What China's Internet Landscape Might Look Like if Google Leaves

China's Internet landscape -- search, digital marketing, mobile media, services like e-mail and even e-commerce -- could shift dramatically if Google does pull out of the market.

The biggest changes will be in China's search market. Baidu, already the leading search engine site in the mainland, is Google's chief rival and will almost certainly soak up more traffic if Google.cn is no longer an option. Baidu may become too strong, with less incentive to innovate. And Chinese sites such as Tencent's QQ may also muscle in.
