I've been into podcasts more and more lately. Terrestrial radio with all its commercials and censorship just doesn't do it for me. Tons of content is available all for free, it's awesome. Dan Carlins hardcore history is a must listen, especially the series on Ghangis Khan.
His new one, Blueprint for Armageddon is amazing
I've listened to all of his history podcasts (even the ones you have to pay a couple bucks for) they are all as good as the one about Ghengas khan BUT...You have to...have to..have to listen to his podcast Prophets of Doom. I've listened to it twice now. I'd like to say its my favorite one. But picking a favorite is impossible
I'm a history podcast junkie. If ya ever want any ideas on good ones let me know I've got a ton of suggestions I can send your way

. I stopped listening to the radio years ago Ill work around the house all day and the wife will ask me "whatcha listening to?" My response is usuall something like " ohh just a 199 part podcast on the history if Rome" I'm a history geek I'll admit it. Lol.
