In a Hardtalk interview first broadcast on Tuesday 10th July, Stephen Sackur talked to the former Director General of the BBC, Greg Dyke.
The first boss of the BBC, the arch paternalist Lord Reith, declared his mission was "to inform, educate and entertain".
Eighty years on, in a broadcasting world of dizzying digital choice, do we still need the BBC and its Reithian values?
Greg Dyke was, until three and half years ago, the BBC's Director General.
Now he's back in commercial broadcasting, Stephen Sackur asks him about the challenges facing the world's biggest broadcaster.
HARDtalk can be seen on BBC World at 0430 GMT, 0930 GMT, 1430 GMT, 1930 GMT and 0030 GMT.
It can also be seen on BBC News 24 at 0430 and 2330.
