I have decided upon Dr. Finer's suggestion to develop this idea further by looking more specifically at how the market was changed by the introduction of not only eBooks, but of the technology itself.  Things like the Kindle and the Nook have been so successful while others that succeeded so well in the 90s are now bankrupt and bought out. (i.e. Borders).  From there I will look at some of the advantages this presents to authors as well the intriguing opportunities it presents to publishers, editors, and booksellers.
