People have signed up for Verizon's FiOS service, which provides fiber optic Internet and cable, will now have access to a new feature called the Widget Bazaar. This feature gives you access to all sorts of apps and information right on your TV.
You can use Twitter and Facebook using the new widget system. Both are pretty limited at this point, though you can receive updates on what others are watching. Twitter can even stay on the screen while you watch TV, if you wish.
The only real drawback is only one Facebook profile is supported per system at the moment. Other widgets available soon include blip.tv, DailyMotion and Veoh. In six month's time, 40 new apps should be available for FiOS customers.
