Robin Li, chairman and chief executive officer of Baidu commented, "Baidu recorded stellar results in the third quarter driven by rapid growth in customer spending and user traffic. In particular, spending by large customers significantly outperformed our expectations as we continued to build strong relationships with high quality companies. China's search industry is still in its early stages, and as the clear industry leader we see enormous room for continuing growth as users and online marketing customers become increasingly sophisticated."
