The DVD can also hold up to four full movies on one disk. Because of the large capacity of data that can be held, the distribution and duplication costs are lowered, which lowers the cost to the consumer. The DVD has integrated interactivity in which it is possible for the player mechanism to be directed by the user to go anywhere on the disk and start playing. Along with the random access features there are also parental control features built in, so that a parent can decide what version they want their children watching. One last feature that stands out in DVD's is the capacity to support up to eight languages.
Society wants the convenience of having quality video without having to go somewhere else to see it.
DVD allows this convenience with some extra perks. Titles of movies are limited and machines are still on the high priced side. Having these DVD's available to consumers at lower prices would have its advantages, of course. But if we did not have them, I think it would be still in the future until the consumer actually would feel as if they were hurting not having this technology. As a technology person, I am always looking for something that stores more data with out saving to different disks.
