I have discovered two places for the history buff to feed his or her habit.
The first is free. The Gilder Lehrman Institute has a couple of dozen podcasts lectures on various history topics, always by someone who has written the book. More are added every month, and they vary is quality from very good to amazing. Even if you don’t have an ipod or iphone, you can listen directly from your computer.

The second costs money. It’s the Teaching Company and they sell courses on audio, DVD or CD on several hundred topics. The courses feature well known academic experts who can be lively and entertaining as well as knowledgeable. Currently I am working through a 36 lecture series on the crusades.
