I was looking through my older posts when I came across the one about DC pulling titles from the Kindle Fire (the comixology app, to be exact). That was a rather curious story, and I still don't have an explanation for DC's actions. That post inspired me to look at the Kindle and Nook stores to see which one had the better selection.
After a spot check of a half-dozen titles, it seems to me that the selection is identical. Weird. I can't explain it, but I would guess that there is something going on behind the scenes. DC very carefully put the same titles in both ebookstores - the ones they added to the Kindle Store 8 months ago.
I would hazard a guess that DC doesn't really want to be in either ebookstore; that's why they never added any more titles to the Kindle Store. If I'm right then this new content for the Nook Tablet is probably going to be a one time deal; it was a way to make piece with B&N after the fracas last year (when B&N pulled DC titles from store shelves because the digital editions weren't listed in the Nook Store).
Any ideas why DC is limiting the selection?
One possibility is that they're avoiding getting in the middle, but I think it more likely that they don't want to pay to convert a title 3 times (comixology, Kindle, Nook). That cost might be fixed but it's not cheap.
P.S. If you noticed the similarity before me and want to count coup, go ahead. My ego could do with some shrinking.
