We, as a modern society, are producing an enormous amount of content these days and I’m wondering what types of schemes we’ve come up with to store and archive all of this. It seems like shows like The Daily Show routinely pull up news clips from 5 or 10 years ago so there must be some system by which they can pull up this content.
I’m assuming the major networks keep a copy of their broadcasts but what about local news stations? Community public access channels? If I wanted to see the July 18th, 1994 nightly news from Muncie, Indiana, how would I go about doing that?
What about ads? Are they archived by some central authority or is it up to the owners of the ads to figure out how to store them?
Are newspapers routinely stored? I know large newspapers like the New York Times have their complete historical archive but what about regional newspapers? Is each copy stored indefinably or do they get discarded after a certain number of years?
What about books? I know the Library of Congress is vaguely involved somehow but I’m not clear on the specifics.
Also, songs, movies, radio broadcasts, etc. How are all these things archived?
