They’re reportedly receiving more requests than expected and are keen to exploit staff involvement beyond their usual spheres.
Requests from staff to do them or listeners for more podcasts?
Either way though it can only be a good thing. I'd imagine that, beyond compliance/licensing, they are relatively cheap to produce.
I'm a particular fan of Brexitcast - it started out quite niche but has settled into a great format - bringing brexit knowledge together with an accessibility that I don't think I've seen from many other outlets. This is probably evidenced in the win at the Podcast awards in the last few weeks. I hope that it continues as a regular political podcast after brexit over (assuming it ever does), and more pop up in the same mould.
P.S. Wish they'd hurry up with Chromecast support in BBC Sounds - getting ridiculous now!
