I was looking at some data of Graphic Novel (GN) payment vs Picture Book (PB), for artists with similar years of experiences, GN are paid better than PB. But Why?
I understand that GNs are often much longer than PBs, and artists deserve better payments if they are devoting more time and energy.
The question I am asking is from the perspective of market size. I would think when PB readers grown up, some of them become GN readers. A small portion would probably lost interest in reading, because of attractions coming from games or other activities. So the market size of GN is smaller than PB. If that is true, profits of GNs should be smaller than PBs. What am I missing here?
Thank you!
