Definiton and purpose of a digipak

Definition of a digipak: A digipak is an original styled CD/DVD packaging, and it includes different elements inside. 
A didgipak helps to promote the album and list what is actually on the album itself. A digipak makes the album look more appealing so it makes the CD look more appealing for customers to buy as it is in a fancy case and comes with others things as well as the CD.
A digipak helps to show customers the re-occurring theme of the artist or group through their CD's and other products so that are recognisable and easy to see who it is and appeals to the right people that are interested in the artist or group and want to buy the digipak. This product helps tell the customers and buyers of the digipak a bit more about the album and the producer and singer within it so that they can get more involved and so that they will pay for a digipak rather than just the album.
This helps the artist or group to put across a message through the art of the digipak cover and interior of it so that listeners can understand the music more and the message that it is trying to portray. These digipaks helps to attract people outside of the fan base so that they appeal to a wider range of audience so that they increase their sales and add interest onto the artist or group overall.
