The ABC in Australia has a series of TV and radio spots that bring interesting public talks to the audience who couldn't be there. It has a rather unfriendly name of ABC Fora.
For a long time, I thought it was something to do with plants but over time I've, mostly accidentally, heard some fantastic talks from this program.
It's on TV on Sunday nights on ABC2 at 6pm and Thursdays at 5.35pm.
It's on Radio on Radio National on Wednesday at 6pm and Thursday at 3am.
Oddly, I think I've heard the 3am broadcast more than the others.
The best way to access this material is via the web here.
The podcast feed is here.
The whole project is a partnership with FORA.tv which has some great stuff.
I'm starting to find that broadcast media - TV and radio, is basically a way to find out about what's available on the Internet.
