The document discusses the effectiveness of combining a music album with ancillary promotional materials like a music video, digipak, and magazine advert. It notes that these materials promote each other by drawing audience attention across the different products. For example, someone who enjoys the song on the magazine advert may then be tempted to buy the album. Together, the package of materials creates synergy by connecting the products so that success of one can benefit the others. The document concludes that the final products were well linked to promote each other, though a lyric booklet could have improved the connections further.
