It seems like the answer is always DVD.
Maybe it's like that:
"A company named Matshusita first introduced DVD in 1995. They can store
more information than compact discs while having the same dimensions. There are two
main types of DVD :
DVD-video and
DVD-audio.
DVD-video is the one that many people are familiar with for watching movies
in their homes. DVD-audio is similar to a music CD. Both types can also be
used on a computer. DVD allow a large amount of high-quality information to
be stored at little cost."
