Dark Horse’s site has a brief article (link below) on being named Manga Publisher of the Year by Diamond Comics Distributors Gem Awards. This being Dark Horse’s 25th year of publishing this makes a nice feather in the hat for them. Out of the 25 years, the site mentions they have published manga for 23 of those years, most notiably Oh My Goddess! and Blade of the Immortal.
