I just seen a post about a fire that destroyed most of the original masters of music and some old films

All too often do the creators or the companies that own the originals not properly preserve them, look at how many episodes of TV shows like Doctor Who went missing for years because they did not have the tapes anymore, or how Wizards of the Coast had to ask fans of the Dungeons & Dragons pen and paper tabletop game to scan their original books to provide to them so WOTC can use them to sell as ebook versions.

Stuff like this should never happen if they truly cared about them.
