A second screen for your TV
While you're watching a giant lizard on your TV, "second screen" apps add an extra social and content layer to the experience. NEW YORK (CNNMoney) -- While you're on the couch watching American Idol, chances are you're also updating your Facebook status on your smartphone or tablet, or hitting Google for the name of that ubiquitous character actor you can't quite identify. There's also Twitter. Posts on it set during the Super Bowl, one at halftime and another just two hours later at the game's end. It's an advertiser's dream: not one, but two screens to capture consumers' attention.
