Analyst ABI Research has published a report predicting that cumulative all-time revenues from mobile apps will pass $30bn by the end of this year, nearly double the milestone reached at the end of 2011. This includes paid apps, in-app purchases and subscriptions, and in-app advertising. “Consumers’ high interest in apps has for long time been obvious from download volumes, but it’s 2012 that will go down in history as the year when the economic side of the business finally took off,” reckons senior analyst Aapo Markkanen. “We’re no longer talking only about a short-term gold rush. Apps have become a major digital industry.” Which is true, although it’s important to note that a lot of people are losing a lot of money making apps that don’t succeed, while the biggest revenues are concentrating around a relatively small slice of overall apps released.
