SHANGHAI, Oct 27 (Reuters) - China's top search firm, Baidu Inc (BIDU.O), expects the negative impact from the transition to its new keyword bidding system to extend into the first-quarter of 2010, Haoyu Shen, vice president of business operations, said on Tuesday.

Baidu had said on Monday that the transition to a new advertising technology would crimp revenue in the current quarter, sending shares plunging nearly 13 percent. [ID:nN26209688] (Reporting by Melanie Lee; editing by Ken Wills)
