I would like to know what the most popular franchises of all time are, when viewed through the lens of Comiket.
By "Comiket-related metrics", I mean things like: number of circles participating; number of distinct doujinshi sold; total number of doujinshi sold; or any other such metric that you think would make sense. I'm not sure which of these metrics have data readily available, so any of them will do, really. I'm looking for data taken in aggregate since Comiket 1 in 1975, or at least as far back as data is available. I'm not looking for information about what was most popular at C87 (the Dec 2014 Comiket) or any other recent Comiket in specific.
Now, that said, I'm fairly confident that the number-one most popular of all time is going to be Touhou - it's been at the top of the Comiket "charts" more or less sincefor a long time now (in the comments, Logan suggests it came outbecame really popular in 1996, as far as I'm aware2002). So what I'm really interested in knowing is what comes in second place on down. I really have no idea what might even be on the list besides Touhou - maybe something long-running like Nanoha or PreCure or Gundam?
