The document discusses the effectiveness of combining a music artist's main product (music video) with ancillary tasks (album digipak, magazine ads, billboards).
It finds the combination is effective because the ancillary tasks use consistent themes, costumes, locations, and imagery as the music video, allowing audiences to easily recognize and link all of the products together. Quotes from the song and the artist's facial expressions are also consistently featured. Using the same visual elements makes the artist and their brand more memorable and recognizable to audiences.
