There are many ways of measuring smartphone success and, using almost any metric shows both the iPhone and Android doing pretty darn well.
That said, new numbers from Millennial Media offer up an interesting take–just how are the smartphone leaders doing in terms of making money for others. The report looks at both how many ads are being viewed on various devices as well as how much app revenue is being generated via the various smartphone operating systems.
In terms of advertising impressions, Android is the clear leader, with devices running that operating system accounting for nearly half of all ad impressions shown last month. Measured on that basis, 14 of the top 20 devices run Android, though the iPhone still tops the list and the BlackBerry Curve is the second most common phone model.
However, in terms of app revenue by platform, the numbers are largely reversed, with iOS apps generating 47 percent of revenue, as compared to 36 percent of revenue generated by Android apps. BlackBerry apps accounted for 7 percent of sales, while WebOS, Windows Phone, Symbian and other operating systems combined for just 10 percent of app revenue.
