Couldn't you just have the TV show or commercial flash a QR code on the screen, or on the corner of the screen? I've already seen subway ads using QR codes, though I'm not sure how effective they are. The business model sounds solid though - advertisers flash QR codes on screen, users scan it with their app and are entered into contest/sweepstakes. Once contest is over they get a message on the app stating if they've won or not, and informing them of new/upcoming giveaways. The only hard part would be convincing shows and companies to participate. They have incentive but I imagine they'd want to see numbers in regards to cost vs viewer acquisition, or perhaps loyalty. Pretty interesting stuff..
