Here's a clip:
From what I understand it appears it's basically like the Blind Auditions, except the show must be live, the act is separated from the studio audience and judging panel by a massive curved screen, viewers vote on an app in real time on whether they like the performance or not and as people vote their Facebook profile pictures appear on the screen to show they've voted. If the number of votes goes over 75%, the screen lifts up and they progress to the next round...don't know how the rest of the show works though.
Oh, and it seems from watching that video that if a judge presses a button and likes them, it gives a +7% to the total.
Interesting concept, but do we really need more of these shows? Nothing beats X Factor.
