Old Time Radio - Surviving radio show recordings (169 series–over 12,000 individual shows) from the 1920's to the 1950's–all in mp3 format and downloadable (most of the time - the site seems to be a bit dodgey due to being a beta version). There's a few science fiction shows (Dimension X, X minus One, Mysterious Traveler, etc.) that became the basis for the Twilight Zone and Outer Limits and so forth, as well as numerous comedy and variety shows. There's even some old newscasts (including BBC's copies of Churchill speeches).
