Because a billion is a nice round number, and if you compare to other companies the same size, they've had a remarkably small number of acquisitions. Google has had Youtube, DoubleClick, Android, Motorola, Nest, HTC, Nest, Looker, Fitbit, Waze... and that's just what I remember. Facebook has had at least Instagram, WhatsApp and Oculus, but they've been around close to two decades less. For a company of Amazon's scale, it's lack of acquisitions is relatively surprising.
