There has been a massive rise in the last decade of CD and DVD duplication since the technology to be able to duplicate a CD or DVD has become a lot more affordable and accessible. CDs are a very popular form of media for music, data and games and people find it much easier to back up their favourite music CDs or games onto CD to allow them to protect their original. When people work on a computer it is now possible to store vast amounts of information onto a CD rather than leave the information on the hard drive. This enables data to be portable and to be given to other people to share information. With the rise of digital cameras it is efficient to store the digital photos onto a CD so that they can be stored alongside normal albums.
