ELI5:How do shows like the Daily Show pull clips that may be several years old to make very specific points?

With the second coming of John Stewart on Colbert this week, I was reminded how specific some of the clips they find are.  Is there like a data base for every news anchor somewhere? I have no idea.

This has been asked before and iirc, the answer was that there are companies with the sole purpose of recording TV and categorizing it on servers that shows like the daily show can pay to search through.
