Yahoo (NSDQ: YHOO) has acquired a 30 percent stake in Indian telephone-directory search service called Call Ezee, which is owned by Network Management Co., reports Reuters. Yahoo’s cash infusion will help the company expand its reach from covering 14 cities to up to 50, and grow its information data base five-fold to 10 million numbers. It also seeks to improve call volumes by up to 10 times by year-end 2009. Currently, Call Ezee is estimated to generate about 10,000 calls a day, according to San Francisco Business Times. The company’s competition includes Google (NSDQ: GOOG), which has launched local search in India; JustDial; AskLaila, which is creating local search content and reviews about companies; and Guruji.com, which is funded by Sequoia Capital and is primarily Internet based and is becoming more of a general search engine for India.
