DVD (Digital Versatile Disc) is an optical disc storage format that can be used for data storage. It is a medium that can store data with very high video and sound quality. DVDs resemble compact discs. Their diameter is the same (120 mm (4.72 inches) or occasionally 80 mm (3.15 inches) in diameter), but they are encoded in a different format and at a much higher data density. They can store any sort of digital data.
Upon its introduction into the market, the DVD format became the most successful consumer electronics product in history in a very short 3 years. It has since become the standard for the entertainment and video industry. Film companies almost exclusively take advantage of this medium to deliver high resolution video content and special bonus features on DVDs that you purchase for your home library. DVD is the epitome of a dynamic way to deliver video, and provides the best quality from original master content.
The applications of DVD are endless for business marketing and communications. Increasingly, companies and organizations are using the medium as a method to not only deliver video content, but to deliver software products, multimedia presentations, and marketing information. Animation studios, film houses, independent film makers, and television studios are all using DVD as the standard for product releases to providing entire seasons of popular television shows.
