July’s almost over, and while I’m not totally done tracking releases for that month, I think it’s reasonably safe to say none of them are likely to snag an elusive top 20 BD/top 30 DVD slot – Naruto and Hetalia were the only series to spend multiple days in triple digits and neither cracked the top 500.
This August looks pretty thin in terms of series likely to chart: the only releases currently better than 20,000th are DBZ’s sixth BD set, Love Lab, and Shinsekai Yori’s second half. Tracking them, as always, to add to the dataset and hopefully eventually enable analysis of the US market.
Despite the fact that both get released in compiled volumes costing somewhere between 400 and 1000 yen a few times a year, the market for manga differs in many ways from the market for light novels. For one thing, it’s a much smaller scale market; the most popular light novels sell hundreds of thousands of copies immediately after their release, rather the millions that One Piece/Fairy Tail/Attack on Titan bring in. Too, light novel adaptations tend to succeed much more as a function of their initial popularity than manga does. To get an in-depth look at how anime adaptations of light novels have impacted the source material, I’ve plotted the sales for their first two weeks of solicitation over time, with the airdate of the anime superimposed. See this doc for the raw data, and compare the 2011data for manga adaptations.
Note: I plot the two-week totals, rather than the one-week total, because even the average the first week total is vulnerable to a series that comes out on the last of the Oricon tracking period and having its sales numbers hamstrung. Kore wa Zombie Desu Ka had 4 volumes in a row come out on the last day of the week, obscuring a very real anime-fueled boost in sales.
