I've done a lot of looking at the e-publishing, web digital writing market. I'm a senior and seen a lot of changes which started for me in 1984, when joining SCBWI, Society of Children's Book Writers and Illustrators. At that time the libraries had their funding cut, and the bookstores emerge. Today lots of change in book publishing, the booming e-publishing where authors write, product, and market their own stories.
-->Millions of ebooks are sold! Soon readers on the many different electronic 'devices' will buy a chapter at a time. A good price per chapter is 99⍧ as an online song once cost. --->A 'series' book chapters as will be sold; check out wattpad.com and Jupebox.com, to mention a few sites. Where a Beta reader reads a chapter at a time and make comments to better the author's work. Why not have the reader pay for this time and privilege?
---> Back in the history stories were told by letters or hand drawn book, we still write individual letters. Think of the value of this process in today's cost of time, physical material, and postage, pieces of art, yesterday's cards --->Then printing machines were invented, and stories printed in newspapers as a series. The author earned a penny a word; I read a lot of those wordy first novels.
---> SO today, gear writings for this change, 'serial chapters' in the digital publishing. Use less words to create a simple, clean story to be read a at one time in our busy time. Also, as any excellent writing have a strong hook at the beginning of the chapter and stronger hook at the end of that chapter, so the reader buys the next serialize 'chapter' in your novel.
