I track US amazon anime releases from one week before the first release date (Tuesday) of the month to one week after, and have been doing so since March of 2014. I’m leaving the data here so that people can more easily browse it if they so desire. It seems to be somewhat useful in predicting what has a chance of actually making the US Blu-Ray charts, though it has been difficult thus far to nail down what exactly a given rank is worth. I don’t necessarily track all releases, just those that are on amazon and show up under the anime/coming soon labels when I check them at the beginning of each month, but I do have data on over 150 releases at this point.
Note: There are
2 5 releases I have tracked and subsequently seen chart: Dragon Ball Z Season 3 on BD (7472 copies in week 1), Attack on Titan Part 1 (BD/DVD combo pack, 11,748 copies in week 1), Attack on Titan Part 2 (10,677 copies in week 1), One Piece Film Z (6199 copies in week 1 on both BD/DVD combo and DVD-only editions), Dragon Ball Z: Battle of Gods (86,735 copies in week 1, 162,228 over 4 weeks). I also have data for various movies (which came out earlier than I started tracking) and data which suggests that ranking 120,000th place or worse in a given day corresponds to a title selling zero copies on amazon.
Note 2: The Initial Data pages are blog posts containing the full titles and links to the relevant items on amazon. The Final Results pages are google spreadsheets that use abbreviated versions of the release titles.
Note 3: Due to personal circumstances, I was unable to access the internet regularly between May 25 and June 8, 2015, so data between those dates is very incomplete. I apologize very much for any inconvenience this causes, and am looking into ways to automate the system.
Feel free to ask if you have any questions!
