That's a big question.
I think one of the key challenges we're seeing as we're migrating from conventional content distribution systems to online is around how content gets made and how it gets the economic model for it. In our case, it's how artists and creators are being compensated for it. One of the big challenges we're seeing is that, as audiences are moving, revenue models are changing, and that's impacting the ecosystem in any number of ways.
We have a short window in which to answer, but I'd say that's the major challenge out there, that we're migrating from more a conventional system to an online world.
