News Corp acquired a controlling 51% stake in Jamba from VeriSign for a reported $188m (£108m) in 2007, following which the two formed a joint venture with News Corp’s Fox Mobile Entertainment unit.
Jamba creates content such as wallpapers, ringtones and games for mobile phones.
It also produces short, made-for-mobile episodes of certain Fox television shows such as 24.
VeriSign has been trying to divest its slower-growing businesses to focus on its core internet security services for some time, and the Jamba sale marks the latest step in that process.
