Marc Zicree and I started up a semi-regular podcast during the most recent Writers Guild of America strike. We realized we know a lot of folks who might have a few things to say about the creation of television shows and films so we decided to wrangle them in front of a microphone and hear what they have to say.

If your interests run to computers (Macs or Windows, Linux or Ubuntu), gadgets, food, google, home theaters (and they probably do) you owe it to yourself to check out Leo Laporte. Hands down, he’s the hardest working man in tech today. The conversations are funny and informative. Great stuff.

Claude Brodesser-Akner covers the goings-on in Hollywood with humor and style. This is the stuff that “Extra” and “Entertainment Tonight” think you’re too dim to understand. You’re not.

On the Media
On the Media explores how the media 'sausage' is made, casts an incisive eye on fluctuations in the marketplace of ideas, and examines threats to the freedom of information and expression in America and abroad. For one hour a week, the show tries to lift the veil from the process of "making media," especially news media, because it's through that lens that we literally see the world and the world sees us.
