That's the term given to the practice of writing long story arcs so they can be repackaged and sold as graphic novels, more specifically the trade paperback kind of GN. ICV2 reports that DC blames the phenomenon for slowing sales of pamphlet comics.
OK, but if you're gaining sales in GN formatted comics, what's the problem?

I wonder if this move will affect graphic novels sales in a significant way. My initial thought is "probably not," since we all know pamphlet comics are not exactly a growth market, and GN's were chugging right along for a while there, though they've slowed too, and we do live in a "What have you done for me lately?" world.
