Since history podcasts are a focus on Anne is a Man!, I can compare to many, many other versions of World History. By all means, Herbst's series is very good; splendid lectures with great many details and delivered in a comprehensive framework. However, it is yet another great quality I would like to pick out here. Not only does Herbst dig into the main stream World History, the direct roots of the Western World, that is, Christianity and the Classics with a touch of Byzantium and Muslim world.

Other areas in the world Herbst has touched upon were Armenia and Ethiopia. By this he filled a gap in my knowledge and possibly for the large majority of us. And what he taught about Persia, I would not have known anything about, had I not listened to In Our Time on the Sassanid Empire.
In short, UC San Diego's MMW courses are an outstanding addition to the history podcast world.
