SF writer Cory Doctorow is mad as hell about Marvel and DC's joint attempt to monopolize the term "super-hero":
"Super-hero" isn't Marvel's property. They didn't invent the term. They aren't the only users of the term. It's a public-domain word that belongs to all of us. Adding a ™ to super-hero is a naked bid to steal "super-hero" from us and claim it for their own.
