Amazon's Net US Ad Revenues, 2011-2015 [CHART]

Chart - Amazon's Net US Ad Revenues

Amazon has already developed its targeting technology, along with creating its own demand-side platform (DSP) to improve targeting of Amazon buyers on other web properties and devices like Kindles—something that may help position them as a more attractive site for both brand and direct response advertisers.
