Google earns over 1 billion dollars from mobile platforms in 2010.

“Mobile is on an annualized run rate of over $1 billion. This means the people who are accessing our products and services through their mobile phones are adding a $1 billion annually to our existing revenue streams. Clearly, this is the future of search in the Internet, more people in more countries coming online from these smartphones. Our mobile search queries have grown five times over the past couple of years. And of course, a lot more of those queries are now coming from Android phones.”

According to a Gartner research Android will have a market share of 30% (currently 18%) at the end of 2014 and becomes market leader.
