Of Barnes and Noble. Well, not entirely. Mostly just comic books, leaving their large assortment of graphic novels in the halls of that very large book seller. This was a move by Marvel, not by B&N. The comic books were never a large part of the market in bookstores, usually sandwiched into the graphic novels and, I suspect largely lost to vie. Comics require a rather special frontage.
The bookseller continues to tread water, not only have sales of digital content dropped almost 21%, book sales in general have dropped about 4%. Toys, games and puzzles have managed to grow somewhat. Throw in some SEC investigations and B&N is bleeding in the water.
