Similarly, Amazon has made streaming media so easy that the practical incentive to buy diminishes. Renting or buying digital video from Amazon, for example, never has to involve a download. You never really have to “have” it. It simply streams from Amazon’s cloud to apps, browsers, and over-the-top internet TV boxes. The setup would seem to work to Amazon’s favor because you’re still paying Amazon money—but not as much, perhaps, as you’d pay to own.
