Immediate floppy diskette obsolence has been predicted for decades.
The ISO Standard (IBM) format has survived while many non-standard
others (Atari, etc) are gone.

Manufacturers survive by developing and marketing new technologies,
and support older ones only so long as there is a large installed
base. The large number of CD and DVD read drives indicate long-term
support.

Retrieval systems for high quality CD and DVD discs based upon ISO
Standard formats should be around for a long time. It is not
predictable whether writers will still be around for that period,
but that is not the issue.

CD-DA is defined in CEI IEC 908, CD-ROM is defined in ISO/IEC 10149,
and DVD-ROM is defined in ISO/IEC 16448. Proprietary Philips color
books are Red for CD-DA, Yellow for CD-ROM, and Orange for CD-R and
CD-RW.
