There’s a good quote on whether ‘behind-the-scenes’ qualifies as transmedia from the book Transmedia Storytelling:

“Despite the growing ubiquity of transmedia, we need to avoid confusing general transmedia extensions with the more particular mode of transmedia storytelling. Nearly every media property today offers some transmedia extensions, such as promotional websites, merchandise, or behind-the-scenes materials — these forms can be usefully categorized as paratexts in relation to the core text, whether a feature film, videogame, or television series. As Jonathan Gray has argued in his defining work on the topic, we cannot view any text in our media-saturated age in isolation from its paratexts — for instance, films come pre-framed by trailers, DVD covers, and posters, and once any text enters into cultural circulation, it becomes part of a complex intertextual web.[2] However, we can follow Gray’s lead by distinguishing between paratexts that function primarily to hype, promote, and introduce a text, with those that function as ongoing sites of narrative expansion that I will explore here; I would add a third category of orienting paratexts that serve to help viewers make sense of a narrative, as discussed in its own chapter.”

Is it worth exploring transmedia storytelling that is deeper than this in your own work? That moves beyond ‘promoting’ your story to ‘telling’ another part of it?
