Other companies have tried--and failed--to marry the worlds of the Internet and TV. Yahoo is hoping to change that with its new ConnectedTV service. The service will require an Internet-connected TV (many of which also have been announced here at CES); that will allow you to visit a Yahoo site where you can browse and download available widgets right to your TV.
These widgets--which will be created by third parties like YouTube, eBay, or Flickr--overlay Internet content on top of your regularly scheduled programming. You could select the eBay widget from the dock at the bottom of your screen, and shop as you watch TV. Or you could hit a Twitter widget, and begin "tweeting" about the show you're watching in real time.
