I have just found this article in MocoNews. There they state that:
News Corp has confirmed it’s trying to sell its former Jamba mobile content unit, after announcing it’s writing off some of the value of the group.
COO Chase Carey told investment analysts on Wednesday about Jamba: “We are pursuing a process to potentially sell that. We prefer to build businesses than buying them. It’s been the foundation on which we’ve built this business. It’s certainly what we plan to pursue.”A News Corp spokesperson subsequently confirmed to mocoNews.net: “Jamba is Fox Mobile Group. So Chase’s comments refers to both.”
For the fourth quarter ending June 30, News Corp says it’s writing off $217 million from the value of its outdoor and mobile businesses, in impairment and restructuring charges; though it’s not clear how much relates to either of the two components.
