I am struggling to find the appropriate term to define everything related to a text that it is not the text, or the book as a physical object. I mean everything from websites to merchandising, video games, apps, etc. I don't think that it is paratext or peritext, and I am sure there must be a word that implies all these, but I can't find it. Any thoughts?
Suggestions over there: "Cultural peritext", "paratext", "collateral", "peripherals", "authorized extensions", "deuterocanonical", "Ubertext? Untertext? Schadentext?", "Supporting material", and "ancillary material"
None of those feel quite right though - and it feels like there ought to be a word for this.
