I think the DC Dredd comics were yanked because no bugger was buying them. The film probably had something to do with this, but the fact that the comics were terrible as well can't have helped.
I think the character's a property owned by Rebellion (2000AD's current publishers), or licensed by them from Egmont (2000AD's prior publishers, who acquired all of Fleetway's intellectual property years ago). I may well be wrong, though."
