> the amazing resources of BBC radio (that precede all modern internet podcasts and the best of which still wipe the floor with most of them) are often forgotten
I don't know, there are some definite bright spots like IOT but the typical output of Radio 4 is definitely not massively in advance of the big podcasts. The Rest Is History/Politics are clearly hugely popular inside the UK and basically constitute "the competition" for your average R4 listener.
I actually think that the podcast model is a big threat for traditional radio. Podcasts are much more lucrative for the makers, the reach is as-big (or bigger) and you don't have to negotiate with the government like R4 does.
