This is a godsend for my pulp-related work right now:
A Day In Radio — On Sept. 21, 1939, WJSV, an AM station in Washington, D.C., recorded its entire 19-hour broadcast day for the National Archives. Everything — news, station announcements, soap operas, quiz shows, music programs, a speech before a joint session of Congress by President Roosevelt (regarding America’s neutrality laws, in the face of the “European War”), and even a Washington Senators baseball game.
Now, 67 years later, I’m sitting here listening to everything in streaming audio via the web. Amazing.
