Amazon has a new platform in beta-testing called Vella. It is a throwback to the way Charles Dickens and others used to write, publishing each chapter of a book in a newspaper in serial format. Throw in a social media layer—readers can “favorite” stories, which earns the writer extra income—and you have the platform in a nutshell.
Unfortunately for writers, you cannot “repurpose” the content by publishing it in book form on its completion, and it’s not clear whether a successful writer could sell the screen rights.
I haven’t decided whether to jump in, but I’m keeping my eye on it.
