Richglib, marvellous !
I haven' bothered checking, but I don't think the BBC has much choice. Also, if they did so with the assiduity you suggest, that would kill 99% of their discussion/chat type shows, mostly because of the length of the lists.
They don't have to have a list on air. Just "the details of the funding are on our website."
Most of these are secretly funded. I wan't to know who is paying for their opinion.
