They're often hailed as a 'revolution in radio', but I just think they're a good listen. I thought I'd put down the ones I listen to regularly, and it would be interesting to see what other people listen to as well.
Really good analysis of the tech (particularly gadget world). My enjoyment of it is limited somewhat because I spend most of the podcast filled with immense jealousy that the US is about to get all of the technology being discussed, but that I'm going to have to wait for ages until a) its brought out in the UK and b) I can afford it!
The World Tech Podcast
This is probably my favourite podcast, for two reasons. The first is that it is a co-production of some US public radio stations and the BBC, and so it achieves a good balance of not being too US-centric. The second reason is that it has great variety, so one report might be on stem cells, the next on Web 2.0, the next on portable music players. All in all, very enjoyable.
BBC radio podcasts
I've lumped these together as I rarely listen to all of them, because there are so many. There are sometimes some very interesting programmes on, and they publish a major interview in the Today Programme every day. Other programmes include In Business, From our own correspondent, Go Digital and In our time.
Quite an interesting set of reports on various different up-and-coming technologies, although not quite as good as the World Tech Podcast in my opinion.
ABC Science Show
Much more interested in science than technology, but it has some very interesting pieces on it sometimes. It is, inevitably, quite Austrialia-centric though. Good for Austrialians I guess!
