Wow, only 10 years. DVD's look like 100-200 years if you keep them in cool, dry, dark storage. So our grandkids will be able to trade DVDs like today's hipsters trade cassette tapes.Among the manufacturers that have done testing, there is consensus that, under recommended storage conditions, CD-R, DVD-R, and DVDR discs should have a life expectancy of 100 to 200 years or more; CD-RW, DVD-RW, DVDRW, and DVD-RAM discs should have a life expectancy of 25 years or more. Little information is available for CD-ROM and DVD-ROM discs (including audio and video), resulting in an increased level of uncertainty for their life expectancy. Expectations vary from 20 to 100 years for these discs.
I already have friends who are buying VHS tapes. Long live obsolete.
