People communicating with entertainment

The end of the cold war also created a reduction in spending for super computing The entertainment industry picked up where the Government left off and many off-shoot technologies were developed which allowed people to interact with entertainment anytime, anywhere.

CD:

The invention of the audio CD was a new high capacity portable storage medium allowing up to 74 min. of excellent quality sound. More durable than the vinyl record and cassette tape, the music CD has virtually replaced both in the consumer market. The CD-ROM allows people to interact with many types of media including images, digital video and sound.

CDs were the first ubiquitous digital optical storage technology

Multilayered Disk:

In 1992, researchers at IBM's Almaden Research Center set out to find a way to pack more information on a disk. They achieved this by stacking two (or more) recording surfaces on a single disk. The multilayered disk could be read by moving the laser's focusing lens and thereby re-focusing the laser on a different surface. This technology is currently used by DVD disks. (below)

Multilayered disks have much higher densities than normal CDs

DVD:

Because of the high capacity of the DVD we can now watch high quality full length motion pictures in multiple languages and/or with subtitles. Additional features can be added such as interviews, "trailers", advertisements, links to the web, how special effects are produced, etc.

DVDs today allow us unparalleled flexibility
