So that I can get this down into the historical record that is the internet, I'm hereby coining the term "podiobooks" to describe books delivered in serialized audio format via XML fees and the tag.
Now let's talk about the timeline:
Tee Morris was the first author I'm aware of to release his novel MOREVI in podiobook format. There had been other sites releasing portions of books and shorstories in podcast format, but to my knowledge, all of those were public domain stories. But hey, I could be wrong. If I'm not, Tee gets the nod as being the first author to take advantage of this delivery format.
Mark Jeffrey quickly followed Tee, podleasing his novel THE POCKET AND THE PENDANT in podiobook format as quickly as we could find a way to make it happen.
Hats off to Scott Sigler for his podiobook EARTHCORE, who stepped the format up a notch by only releasing his book in podiobook format. The books written by Tee and Mark are available in print form, but the only way (for now) you can get Scott's is in podiobook format.
OK. Think that stake is planted pretty firmly in the ground.
