"Although given the NBT was DAT and Minidiscs"
You see what happens when instead of agreeing on a single standard - as it was done with the CD - companies started to multiply them, and making them all incompatible. To replace the compact cassette analogue tape you got DCC, DAT and MiniDisc. All of them had limited consumer success - and were soon replaced by CD-Rs - which were less expensive, and were compatible with a far lager number of devices (HiFi systems, car audio, computers, etc.).
