archive.org has a lot of all images, videos, and audios on a wide range of subjects, all for free download. Like the old radio shows? Martin and Lewis, Fort Laramie, Sam Spade, X Minus 1, CBS Radio Mystery Theater, etc. Want to listen to the radio broadcasts and reports of the Normandy landings as they filtered in and the leaders of governments-in-exile of Nazi-occupied nations made broadcasts (with following translations by the network) to their countrymen? There's enough material there to keep just about any taste occupied for years.
There's so much crap on TV at the moment that I find myself listening to these old radio shows more and more.
