Problem: In some e-commerce sites, the acquisition of content is pretty straightforward. Products are created and/or acquired from suppliers and then presented to be purchased. But what about sites that offer purely digital or even virtual content? How does a site like Netflix make enough money to afford to continue purchasing or creating content from subscriptions alone? Do you foresee this model expanding to other types of media? Is it a sustainable model over time? Discuss where you see this trend going in both the short and long terms.
