The scale on the left side represents average views in a month for each of the mediums: print, epub, social media and web. Small transparent circles surrounding each medium represent the elements they offer including illustration, printed book, digital book, stories, cat for a day and animation. Arrows show if the medium can refer to other mediums with dash lines representing those that were not used during this study.
With that in mind, web offers the most elements, receives the most views and interacts the most with other mediums. Web is essential to a multimedia campaign.
