Targeted advertising on mobile devices is something we’re all getting increasingly familiar with. Visit a web site and there’s a good chance you’ll see an advertisement that’s aimed directly at you, perhaps using information about the sites you’ve previously visited, the type of smartphone you’re using or even your location.

Last year smartphone users spent $8 billion (around £5 billion) for paid apps in the five biggest application stores: the Apple App Store, Google Play, BlackBerry App World, Nokia Ovi Store and Windows Phone Store.

That’s a 27% increase from the previous year, according to a new report from mobile research specialists research2guidance.

Carphone Warehouse Group plc has published an interim management statement for the third quarter of its financial year, covering the three months until the end of December 2012.
