ScoreBig

ScoreBig, which launched in December of 2010, is still in its infant stage, but you'll be seeing them around eventually. The business model is exactly the same as is Priceline, except that it appeals to the 40% of all concert and sporting event tickets that go unsold each year. Someone had to do it eventually, and it will be successful, as long as they do it right.

One potential failure point is that it's nothing more than dynamic pricing for the live entertainment industry; this means that, while you could get deeply discounted tickets for a show that didn't sell all that well, you could also end up getting gouged on tickets for a show where sales soared. It's nothing more than economics and simple supply and demand, but it could definitely get dicey. Just because there are a group of people willing to pay $1K for a t-shirt (there are always a handful of them) doesn't mean it's necessarily worth that amount.

It will be interesting to see how this affects ticket sales and internal revenue in the long-term.
