I get the idea that now the entire model for concert tickets is that they get bought instantaneously when they go up for sale using some kind of software. The tickets change hands a few times between middlemen and then they finally end up for sale at Stub Hub for 10 or 20 times the original price. I remember being a teenager and going to the back of the record store to buy tickets for a concert and walking out with actual tickets at list price. This is an example of e-commerce making everything worse. I wonder how many sold out shows end up with empty seats when the concert starts.
