A month ago, we reported that Yahoo! had tied up with Idea Cellular, an Indian mobile service provider to provide Yahoo's oneSearch service to Idea Users in India.

Now, Livemint reports that Google too is getting ready too as it currently busies itself with building solutions to merge “voice and data” in text messages dispatched from cellular phones, and is hoping to aggressively push these in India, among the fastest growing markets for cellular phone services in the world.

"India is emerging as the largest growth market for Google, as more small and large businesses in the country advertise through Adwords, the target based text-advertising programme of the search engine.”

Shailesh Rao, Local M. D. of Google India Pvt. Ltd said, “The primary killer application is still voice. What nobody has figured out in the world, including India, is what is the proper marriage between data and voice. I think we have an opportunity, particularly in India, to explore that question. It is incumbent on all of us in India to really work hard and figure out what is the proper marriage of voice, for mobile devices in India, so that we can see this kind of data growth."

Yahoo! And Google are looking to not just provide search services but also step into the mobile advertising business like their targeted advertising on online searches.

Google already has a business tie-up with Bharti-Airtel, India's leading mobile service provider.
