A digipak is an elaborated CD cover with at least four panels that allows for information like the album, artist, and tracklist to be displayed. Extra panels can include images. Advertisements promote digipaks and artists, usually including the digipak image, album/artist name, ratings, and tour dates to inform audiences. The purpose of a digipak is to project the artist's image, package and sell the CD, and market the album through logos and thumbnails. Advertisements aim to project the artist image, provide information on availability, and promote release dates and tours.
