Fall 2011 Anime Original Material Sales
AkibaBlog tweeted an interesting link a few moments ago. This is a post by an employee at a general bookstore who calculated the increase in novels/manga for series that started in Fall 2011. This employee started in the first week of October and counted how many were sold up until the 4th, 8th, and 13th weeks of the season.
Order by amount sold in 13 weeks:
Mirai Nikki: 1,731
Persona 4: 1,171
Kimi to Boku: 929
This is ordered by percentage increase from July-September sales to October-December sales:
Mirai Nikki: 1,456%
Persona 4: 549%
Kimi to Boku: 500%
Mashiroiro Symphony:6025% (special case as it was not previously on their ordering list)
Keep in mind that this is a single bookstore that does not specialize in anime goods like Animate. It's just always interesting to see the increase in sales at a normal bookstore due to currently airing anime.
