EDGE - I've been thinking about virtual goods again. They've been big news for a while now. A quick Google search - I mean, my well-honed legal mind - reminds me, for example, that the US virtual goods market is forecast to hit $2.9 billion in 2012. Then I saw that Facebook has announced its planned IPO, as part of which it disclosed that it made $445 million (12 per cent of its total revenue) from its partnership with Zynga in 2011 – nearly all based on virtual goods sales, I imagine. So trebles all round for games businesses selling virtual goods, then?
