Apple responsible for 99.4% of mobile app sales in 2009

The latest report from market research firm Gartner suggests that mobile apps are big business, and that business should only grow in the next few years.

According to Gartner's numbers and those reported by Apple, Apple completely owns this market, likely grabbing almost every one of the 4.2 billion dollars spent on mobile apps in 2009. Based on Gartner's estimates and ars technica analysis, Apple could hold on to at least two-thirds of the market if current sales trends hold for 2010. Gartner's predictions for 2010 are 4.5 billion apps sold, for a total of $6.8 billion in revenue. If Apple can merely maintain its current rate of about a quarter billion app sales per month, and revenue share tracks with market share, it stands to be responsible for 3 billion apps sales—67 percent—good for about $4.5 billion in revenue. Apple's cut would be $1.35 billion, with developers taking the remainder. However, as Apple gains more users from sales of new iPhone models and possibly from an expected tablet, Apple could get an even larger share of the mobile app market.

Predictions for 2013, just a few years away, are even bigger—21.6 billion apps sold for a total of $29.5 billion revenue. The firm predicts that by then, 25 percent of the revenue generated by mobile apps will be from free versions supported with advertising. "Growth in smartphone sales will not necessarily mean that consumers will spend more money, but it will widen the addressable market for an offering that will be advertising-funded," Baghdassarian said. That makes Apple's acquisition of a mobile advertising firm seem like an even smarter move, just for the extra revenue alone.
