In good time for Christmas, Facebook has a new product category for its Facebook Gifts service: iTunes vouchers. Users can now buy the digital gift certificates for Apple’s store in $10, $15, $25 and $50 denominations in the US – the service isn’t available elsewhere. An interesting aspect is the ability for the givers to suggest specific albums or content that the receiver may like to buy with the voucher. Initially, this is all manual on the part of the giver, but TechCrunch points out that in the future, Facebook could mine its data on the receiver, as well as the iTunes catalogue, to make helpful suggestions too (“If someone shares to Facebook from the classic Angry Birds app, it might say you should recommend they spend their credit on Bad Piggies or Angry Birds Space.”). It’s the latest example of Facebook and Apple teaming up, in contrast to the tense relationship they had under Apple’s late CEO Steve Jobs.
