What I mean is that neither Demon Goblin nor Iron Patriot stuck around in comics or in other mediums (Don Cheadle's version notwithstanding) while the classical take on the Green Goblin has continued to appear and, more importantly, to be marketable (Demon Goblin's return in Saladin Ahmed's run, for example, was significantly more forgettable and less marketable than the hype that Gobby's return got in Spencer's run).
