[Steve in Pudsey]

I know that I'm more open to visualised radio (done well) than some other forum members, but still find Nicky Campbell an odd choice for this to go first. Personally I'd've started with something like Today in Parliament. Relatively easy to visualise, clear news value (particularly after the TV equivalent got axed) and in a less prominent slot.

But visualising a phone-in requires fewer changes to the production process than turning Today in Parliament into a TV programme, where you would need the video clips rather than just audio. Maybe not too much of a barrier in these multi-skilled days though.
