Radio broadcasts from the 30's and 40's

I don’t remember what I was searching for. Somehow, I stumbled upon Radio News on Radio Days, which has a collection of Creative Commons-NC/ND-licensed recordings of old radio broadcasts, including Edward R. Murrow’s Orchestrated Hell broadcast of December 3, 1943. I had never heard such extended recordings from this time — just snippets and samples used in other works. These news broadcasts are so very different from today’s TV or radio. It’s easier now for me to see how radio then could hold people’s attention.
