You might be out shopping today in retail stores, but it's the digital app store on your phone that's raking in the dough.
By the end of this year, the mobile app industry will have generated more than $30 billion in revenue since emerging about four years ago, according to a report on mobile markets by ABI Research, a tech analysis firm.
The report takes into account money made from app purchases, in-app purchases (such as upgrades inside video game apps), advertisements inside of apps and also subscriptions.
That's a lot of money, but if you're an app developer, the best news is that nearly half of that revenue has come this year alone. The reason: The digital app market has proved to be a major industry and not just a short-term gold rush, ABI Research Senior Analyst Aapo Markkanen said in a statement.
