“Romance of the Three Kingdoms,” one of the classical novels of Chinese literature, describes wars among three power blocs to replace the dwindling Han Dynasty some 1,800 years ago.

China’s Internet world is now dominated by three kingdoms— Baidu Inc., Alibaba Group Holding Ltd. and Tencent Holdings Ltd. The companies have the power to pick winners and losers among Chinese startups.

The three are so dominant in China that they are widely known as BAT. Baidu, sometimes called the Google of China, holds commanding market share over search. Alibaba holds a similar power over e-commerce. Tencent is the dominant player in social media.

The companies are spending billions of dollars to help them capture China’s rapid shift to smartphones and other mobile devices. That makes them virtual kingmakers among startups.

Their deep pockets and powerful presence in everyday Chinese life have made them both loved and feared by startups. Some see monsters that crush innovative startups, while others see saviors offering lucrative exit options.”
