DVD is short for Digital Versatile Disc, a hugely popular digital information storage format that was developed by Panasonic, Sony, Toshiba and Philips in 1995. Whilst they were the same size as compact discs, they offered much higher storage space, and could therefore include high-quality digital copies of movies and television programmes.
Although they are falling in popularity, with the rise of digital downloads, blu-rays and the ability to stream most movies in high definition, DVDs can still be bought from online retailers and from some high street specialist shops. Most modern movies are still put out on DVD, and the same goes for longer television series, with large boxsets still selling very well.
DVDs of just about any film or television programme can be found, with genres to suit anybody's tastes. As previously mentioned, larger television boxsets are popular, with comedies, dramas and documentaries being put out on multiple discs. Some DVDs are no longer in print, these movies or television programmes will sell for a surprising amount to the right collector.
Blank DVDs can also be bought, to allow people to burn digital data to disc - this data can then be transferred easily by putting the disc in another computer drive. To burn information to a DVD, a special DVD writer is required. DVD cases can also be found, often in bulk packages - these cases protect the data from being damaged, and can also help to organise your data once you need to put it in to storage.
