Amazon famously never gives sales figures for any of the devices it sells, preferring to let its financial results do the talking. Analysts can make estimates of how many devices have been sold, based on their information from sales channels and any guidance the company might give. But it’s not as definitive as, say, the smartphone sales that Apple or BlackBerry include in their financial figures. (They are now the only two companies which give specific values for device sales in their financial results; Apple goes farther by giving the revenue from those sales too.)
But we can have a stab at estimating how many Fire Phones are in use, based on data from Chitika, which runs an ad network.
According to a release from Chitika, looking at activity on its ad network in the 20 days after the Fire Phone’s release, the Fire Phone accounted for 0.02% of activity — although a more precise figure, in another graph, shows it as around 0.015%.
