This is the first word, behind a paywall.
More to follow and I will update this post.
Same-day update: The trouble with paywalls is the inability to get the whole story. And the whole story is that the Nook is not dead. Ownership was transferred from one corporate entity — Barnes & Noble Education, Inc. — to another corporate entity, Barnes & Noble, Inc.. Mere paperwork. The Nook business is not dead. Yet. I wouldn’t be surprised if it goes away in 2016, after it’s been milked dry for the 2015 holiday sales.
