From Knowledge@Wharton: will lose money on each $199 Kindle Fire it sells, but hopes to make back that money and more on tablet users who are expected to spend more than other customers. Sprint is not expected to turn a profit selling Apple’s iPhone for at least three years, but expects that gamble to pay off in happier users who will bring in more subscribers.

The prin­ciple under­lying these moves is customer life­time value (CLV), a marketing formula based on the idea of spending money up front, and sacri­ficing initial profits, to gain customers whose loyalty and increased busi­ness will reap rewards over the long term. It is a model that is becoming more and more popular among tech­nology compa­nies, including Amazon, Sprint, Netflix and Verizon.
