Google during a results call discussing its latest results revealed how much its results lean on mobile and addressed the prospects of an Amazon app store. In a first for the company, Senior VP of product management Jonathan Rosenberg mentioned mobile revenue and said that all of Google's mobile efforts, whether on Android, iPhone or elsewhere, were adding about $1 billion every year to its revenue. The figure put mobile at a large portion of the $7.29 billion in revenue the company reported today.
