What is a DVD?
DVD is the acronym for Digital Video Disc.
Basically, it is a disc storage format for digital media that was developed and invented by the
companies Toshiba, Philips, Time Warner, and Sony back in 1995.
The two main things that DVDs are used for are
data and video storage. They look and weigh just about the same as a CD, but they have the
potential to hold a lot more data.....actually, six times as much data to be
specific.

There are actually several different types of DVDs. The type of the DVD is usually displayed
in the name.
A DVD-ROM is a DVD that is only readable, not writable. A DVD-R
is a DVD that can be recorded on once, after which it functions as a DVD-ROM. A DVD+RW, however, can be recorded
on and then erased several times.
DVDs are considered a high quality digital format for video,
which is why almost all home videos sold in retail stores nowadays are in the DVD format. This is part of the
need for many people to convert from MP4 to
DVD.
However, with the advent of High Definition video, Blue Ray is
now making advancement as a type of high definition video format that is said to be much better. DVD, however,
is still the most widely used type of video format, mostly because not everyone has transitioned to Blue Ray
yet.
While the DVD is probably on the way out when it comes to buying
new movies, it will no doubt remain in use long after Blue Ray has become the movie standard due to its data
storage capabilities.
People in all kinds of professional industries, including the
industries of professional audio and video, use DVDs every single day to save and replay data of all kinds. For
this reason, it will be a LONG time before the DVD truly disappears.
