The Huffington Post launched an iPad app that could help tablets surpass TV as king of our living rooms, writes GigaOm. The app, called HuffPost Live, offers a strong mix of entertainment and social interaction and can throw itself onto a TV screen. The news site launched an online TV network in August that streams 12 hours of live footage a day from New York and L.A. The real game changer is the fact that the app can be slung onto a TV set using Apple TV. This means that Huffington Post has a chance to control not just a living room’s second screens but also the primary one as well.
