The BBC has put out a (big, long) document about Building public value: Renewing the BBC for a digital world. I haven't read the whole thing (did I mention it is big and long?) but here's a couple of interesting bits:

At the heart of Building public value is a vision of a BBC that maintains the ideals of its founders, but a BBC renewed to deliver those ideals in a digital world. That world contains the potential for limitless individual consumer choice. But it also contains the possibility of broadcasting reduced to just another commodity, with profitability the sole measure of worth. A renewed BBC, placing the public interest before all else, will counterbalance that market-driven drift towards programme-making as a commodity. Only a secure and adequately funded BBC can ensure that broadcasting retains its cultural (in the broadest sense) aspiration.

And...

The BBC will launch a Creative Archive – free access to BBC content for learning, for creativity, for pleasure. The BBC’s programme archive is owned by the British people. Until now it has remained largely inaccessible as there has been no cost-effective mechanism for distribution. Digital technology removes this barrier

The creative archives mean that BBC content is available to the public for use in creative projects, for building more intellectual property and for learning. There's also some interesting stuff in the document on public value, public responsibility and a digital future.
