In August 1995, DC Comics chose to sell its comics exclusively through
Diamond Distributor. Several other major publishers followed suit (Diamond
continues to distribute most other comics as well). In July 1996, Capital
City sold its assets to Diamond, and in February 1997, Marvel shut down
Heroes World and returned to Diamond.
For most comic stores and publishers, Diamond *is* the direct market. If
Steve Geppi doesn't want to distribute a comic, most American retailers
won't receive it. So is it a monopoly? The Department of Justice is
considering the matter. Diamond's defense is that comics are merely a subset
of the periodical magazine market, in which Diamond is a small fish.
