I came up with the idea for this type of deliverable during that shaky time period where corporations wanted their sales reps to only use iPads, but then freaked out when they realized their options to disseminate training were limited. I knew PDFs wouldn't pose any testing or distribution issues, and a graphic-intensive deliverable would look great on a tablet. Plus, it was a good excuse to draw stuff. I've helped produce a bunch of these graphic novels since then.
