Might I suggest the No Agenda Show? It is a twice-weekly podcast, streamed live on Sundays and Thursdays and available for download a few hours afterward. Hosts Adam Curry (former MTV VJ and co-creator of podcasting) and John C. Dvorak (tech columnist and writer) take aim at the media and what's behind the coverage.
For over 900 episodes they've been having their chat about the media, relying on the value-for-value model which asks the listener (they refer to them as producers) to support the show with in-kind value to what they get from the show. The production quality is so high that it's hard to believe two guys are doing the live show by themselves for a couple hours.
