[Amazon] started as a “book retailer” and nothing else. They leaned on Ingram’s Oregon warehouse to enable their business model, which was to take an order for a book and accept payment, then procure the book from Ingram and send it to the customer, and then a little later pay Ingram’s bill. This positive cash-flow model was so brilliant that Ingram could have readily enabled lots of copycats, and they formed a division called Ingram Internet Support Services to do just that. So Amazon killed that idea by cutting their prices to no-margin levels and discouraged anybody else from getting into the game. That was in the late 1990s.
They could do that because the financial community had already accepted Amazon’s strategy of using books to build a customer base and to measure future business prospects by LCV — the “lifetime customer value” of the people they did business with. And it became clear pretty rapidly that they could sell book readers other things so no- or low-margin sales were simply customer acquisition tactics. This was a game Barnes & Noble and Borders couldn’t play.
Now book and ebook sales are almost certainly no more than a single-digit percentage of Amazon’s total revenue. Kindle Unlimited, like their publishing enterprises and self-publishing offerings, are small parts of a powerful organization that has many ways to win with every customer they recruit.
