When a TV series is cancelled, but the stories unresolved, the studios could, conceivably, farm out the unfinished production notes to authors to novelise the closure of the story and sell it as an ebook. The costs are almost nil, especially if the author is only paid in royalties, and it gives fans at least something to finish. The upside is that the novel sales, if they are particularly good, could go on to fund a new season of the show, with the sales numbers as a prediction of audience size.

PPS - See how it can all come together?
