DataPlay Discs
Lifespan: March 2001—October 2002
Price: $9.99
Pushed As: Compact-disc replacement
Why It Failed: Its quarter-sized frame was cool, but media consumers found the price of CD-Rs and CD-RWs more fitting. Pre-loaded music discs came with extra features that were annoying to unlock and its write-once capability didn't bode well for those looking to use the discs as back-up storage.
