A.C. Nielsen’s BookScan service has provided ICv2 with a ranking of the top 20 graphic novels of 2008, drawn from sell-through information in bookstore and other outlets tracked by the service. The rankings are based on piece sales for the entire year. Watchmen was the #1 graphic novel of 2008; although it was selling great all year, sales were turbocharged by the Watchmen trailer released in conjunction with The Dark Knight, the #1 movie of the year. Batman: The Killing Joke Special Edition, another 20 year old volume written by Alan Moore, was the #5 title of the year.
