A Google® account is a unified sign-in system that gives you access to free Google services, including iGoogle, Gmail® email services, Google Groups, and Picasa® Web album.
If you use AdWords® or Google Checkout, you already have a Google account. To set up your Sony® Internet TV, simply sign in with your existing Google account. Your account username is the e-mail address you entered your Google account was created. If you use a Gmail account, sign in with your Gmail username.
If you do not have a Google account, you can create one during the Internet TV setup process. The Internet TV device provides on-screen information during the setup process so you can create a Google® account if needed. You can also sign up for one at the https://www.google.com/accounts website.
