Stephen King wrote a story called UR that is available only on the Kindle. King said that he was initially said no to writing a story but then he thought it was a way he could write a specific scene.
Paraphrase of what King said about story:
My wife likes to say that lobster is an excuse to eat butter. For me, sometimes, writing a story is an excuse to write a certain scene. Wanted to write a scene about the phenomenon of reading off a computer and the crisis point that at least the press has made between print media…and the evil Kindle.
UR by Stephen King
Sneak Peek of his most recent book too!
When I preordered his most recent book of short stories for my Kindle, it sent one of the stories right away, before the book was out. I got a great sneak peek that made me look forward even more to reading the rest.
He was the first to do a book entirely on audio, as I recall, and The Green Mile was published as a serial at first, little paperbacks. I love that he is always ready to innovate.
Pink Kindle
Oh, and according to King, since he wrote about a pink Kindle, Amazon.com gave him a pink one, as well.

Books published in serial form
Kings “Green Mile ” is hardly an innovation. Most of Dickens (and many other 19th authors) was originally published in a serial form. It was much more lucrative. King or his publishers must have thought likewise.
