Dunno if this has been posted before (couldn't find anything), but I just stumbled on this cool site containing WWII News radio broadcasts in mp3 format.

Search around the site too for some other little radio gems - I'm currently listening to the 1938 "War of the Worlds" broadcast...I'm glad I'm not in NJ right now...
