Chrome and Apps

Four-year-old Chrome is the No. 1 Internet browser, with some 35% of the desktop market. Apps such as Gmail are growing, with businesses paying for premium versions of the software.
Android
SVP Andy Rubin
Devices running on the Android platform now account for two-thirds of the smartphone market, and Android tablets are beginning to make inroads despite a paucity of apps for the devices.

Includes one of the broadest product portfolios, with major successes like Maps, and areas that are struggling to gain traction, like mobile payments (Google Wallet) and Offers.

The social network is woven into a variety of Google products, from Gmail to YouTube. Google reported 135 million "active" users, but skeptics say it lacks the impact of Twitter and Facebook.
YouTube
SVP Salar Kamangar
With 4 billion hours watched every month, YouTube is the anchor of Google's $5 billion display business, vindicating Google's 2006 purchase of the video site.
