From the responses to a survey I posted a few weeks ago I put together this info graphic outlining the readership of major fantasy sub genres, in addition to important historical milestones for the development of what it is today.
Fantasy as a literary genre has been sadly very under-represented in studies and classification through the years, and as time progresses it has become a significantly more dominant genre in the writing field. It's history is hugely interesting, and I'm really curious to see how it continued to develop!
Thought you guys might like to see it. Enjoy.
