“How long will a DVD last?”
I have seen reports of 75-100 years. This could be wrong. DVDs will last until they become too scratched to be read, and scratching a DVD is not hard to do. Always make a back up copy of important video or data and put the DVD away in a cool, dry place. Exposure to extreme heat or extreme cold can cause damage to DVDs, and they should also be kept away from any harsh chemicals to ensure a longer lifespan.
