DVD or Digital Video Discs are similar to compact discs with one major exception; they can store a lot more data than a CD. Initially, a DVD was used for storing data but very few could afford them. DVD's came into the picture early in the 90's, when compact discs were booming.

Introduced by Pioneer, DVDs were one-sided. Toshiba, Sony and Philips soon followed with their own versions. At the time, the discs were about 1.2mm thick and could contain approximately 2.1GB data.

The amount of data that can be stored onto a DVD has rapidly increased because of new developments in the field by major companies. DVD-read only memory discs are still the most popular on the market, even though DVD-read write memory disks are available. This is because of the price difference between the two. The DVD read only memory discs the best bargain.

In today's market, DVDs are the latest craze in the movie world. Since they can store as many as 3 to 5 movies on one disc, rental agencies are finding them to be a valuable resource. Profits are greater because DVDs are more durable than CDs and can be rented out hundreds of times.
