One million free comics were downloaded last month during a 48-hour giveaway to celebrate the second anniversary of the Dark Horse Digital initiative, the publisher announced.

With a click of the "Buy Now" button, readers could download 50 first issues through the company's online storefront. Worth $168.50, the titles ranged from from the first issues of 1994′s Hellboy: Seeds of Destruction and 2002′s B.P.R.D.: Hollow Earth to far more recent series, like The Massive, Mind MGMT and The Black Beetle: No Way Out.

“The success of our digital promotion illustrates the growing reach of digital comics, which we believe are an important element in the recent resurgence of physical comic book and graphic novel sales,” Dark Horse President Mike Richardson said in a statement.
