See previous post for current Amazon/Wylie Adventuretime In Books.
At a staff meeting recently at one of the big chain bookstores to which I was privvy, there was a brief but interesting discussion regarding the Amazon/Wylie exclusivity venture. Seems that some booksellers have come to the conclusion that exclusivity for e-book titles is detrimental to the growth of the electronic book model.
Basically, if you can only get these titles at Amazon, why would you purchase an iPad/nook/Kobo/etc. And, if this exclusivity thing gets bigger and say certain authors will only deal with Barnes and Noble, or Google, or Apple, then why on earth would anyone in their right minds by any of these devices? You'd have to buy an iPad to read JK Rowling, or a nook to buy Stephen King, and a Kindle to read Updike.
It gets ridiculous pretty fast. Why buy electronic reader for $100-$600 when, well, there's a perfectly good book already on the shelf?
