>>8obviously not true
http://money.cnn.com/2016/01/26/technology/amazon-prime-memberships/Amazon Prime now reaches nearly half of U.S. households
Okay so nearly half. Most estimates put it at around 38%.
to whom is that data valuable besides other retailers
Why does that matter? Amazon is a retailer. If it's logistics data can allow it to consistently get packages to customers within 24 hours at a low cost then nobody will be able to compete and they will completely own the eccommerce industry. Also, every company that runs a warehouse or deals in any kind of logistics would want that data, because it is so comprehensive and at such a massive scale. You forget that Amazon also operates the largest enterprise cloud in the world and controls a significant portion of all data collection in the world. Amazon is gathering massive data on data itself. What is your precious Walmart doing lol?
