Reinventing Google for a Mobile World - The New York Times

From an overview of Google's shifting search strategy

"Google is a mobile force in many different ways: In the United States and several other countries, search queries to Google on mobile devices now outrank search queries on desktop and laptop computers. It has the world’s largest mobile operating system, Android. It makes billions of dollars a year selling apps through the Google Play Store and owns many of the world’s most popular apps, such as YouTube.

But that has created competing priorities because apps have also diluted its position in search. Google claimed 68 percent of mobile search revenue in the United States last year, according to the research firm eMarketer. That lead, while still substantial, was down from 81 percent in 2012, a decline projected to continue as apps occupy more of people’s time."
