On a side note, I've been digitizing some of the family's old 78 RPM records (pre-vinyl, these are acoustic shellac disks). It finally sunk in that these things are over 100 years old - and they are playable, and play better than they did back then (with modern cartridges, amp & speakers).
Bet those DVDs don't last 100 years.
