Best TV shows as podcasts (and potential for future ones)

I subscribe via itunes to NBC Nightly News (which I probably watch one out of three days) and The Rachel Maddow show (which I might find time to watch one out of five).

I used to watch CBS Evening News but just found that I didn’t have the time to watch mostly repeated information from the NBC News that I’ve watched my whole life, so I unsubscribed to it.

I would actually pay to have Jeopardy as a podcast, but all the googling in the world hasn’t shown up anything for it.
What TV shows do you watch as a podcast?

I watch the Australian ABC’s The New Inventors and The Einstein Factor.
