Android: What's in it for Google

Why is Google so aggressive about giving away millions of copies of its royalty-free mobile operating system? It is expected to lead directly to mobile search revenue. Jeffries &Co. thinks Google mobile search revenue will cross the $500 million mark in 2011, up from roughly $180 million in 2009, for example.

Android devices will be available on all four leading U.S. mobile carriers in 2010, so the issue is how much penetration the Android operating system will be able to get.

Beyond what Android means for Google, the issue is what it means for the service providers selling devices powered by Android.

There is speculation that Verizon, for example, plans a major initiative centered around Android to battle the Apple iPhone. Verizon apparently has been mulling the value of getting the Apple iPhone, but might have decided to push Android devices and applications instead.

T-Mobile executives have to be wondering what they will do now that Verizon has positioned itself as a major proponent of Android, as T-Mobile had been touting Android early on as a differentiator.

But if all the top-four providers are selling Android devices, using the software to differentiate user experience might become key. Apple prefers to maintain a uniform interface. Android actually enables differentiated user interfaces. So the issue is whether Android supporters will be able to create end user experiences pitched to particular end user segments that are compelling enough to create viable device segments.

Twitter, social networking, Web browsing, email, voice and texting are examples of lead end user applications that have, or can be, the center of "application specific" device sales and usage modes.

Google expects to win by growing its ad business, no matter how many distinct new niches can be created.
