With virtual good sales already representing the main source of revenue for Social Games on Facebook, we have seen a dramatic shift in the mobile application model this past year towards a similar position. As apps are moving away from advertising as a revenue generator and towards creating in app purchases as the preferred method of monetizing the investment, you will see a shift in not only the style but in the whole mobile application development thought process.
Looking at the rapid growth of the sale of virtual goods in Social Games this is not a surprising trend and it is one that anyone considering iphone application development for their business should consider. If you also consider the fact that mobile applications now rival TV viewing in terms of audience reach you will rapidly see this market continue to advance at meteoric rate to keep pace with the opportunities available.
