The Walking Dead #100 has already been trumpeted as the bestselling comic, in initial orders, since 1997, so it comes as absolutely no surprise that those 383,612 copies were more than enough to lead Diamond Comic Distributors' Top 10 list for July. It's the first time in its nearly nine-year run that the horror series by Robert Kirkman and Charlie Adlard has topped the chart.
However, it also marks another milestone: It's the first time in almost a decade that a comic published by a company other than Marvel or DC has claimed the top spot in the direct market. That honor, in November 2002, went to another Image title, Masters of the Universe #1, by Val Staples and Emiliano Santalucia. Of course, that comic sold about 270,000 fewer copies than the 100th issue of The Walking Dead, according to the invaluable Comichron archives.
Before that, though, the now-defunct Dreamwave Productions had a pretty good run, with its Transformers series leading the monthly sales charts for a full half of 2002.
