Scribd has published the first volume in Scribd Originals, an ebook/audiobook platform designed for stories between magazine articles and full-length books. It sounds a little bit like Amazon Original Stories (formerly Kindle Singles).
At first, I got excited because I thought there might be open submissions, but I can't see any evidence of that, except for a vague statement about reaching out to "authors, agents, and publishers." Listing authors separately gave me hope, but it could just be trad published authors. A number of authors have signed up for future projects already.
The one point of interest is that the content will be exclusive to Scribd. That kind of exclusivity has been common in video but so far confined to Amazon in books, at least as far as I know. If it brings more subscribers to Scribd, it might be emulated elsewhere. Interesting fuel for speculation, anyway.
