You probably already know that the DVD is destined to run videotapes and compact discs off the planet.
The DVD far eclipses videotape for movies and shames the compact disc for music. In data storage, at 4.7 gigabytes it beats a rewriteable CD about sevenfold.
There's really no need anymore for CD-ROM drives in computers, as DVD-ROM drives, which cost less than $100, can read all CD-ROMs and standard audio CDs.
