The immense popularity of The Dark Knight Returns served both to return the character of Batman to a central role in pop culture, but also (along with Watchmen) started the era known as the Dark Age of Comic Books (also known as the Modern Age and the Iron Age).[1] The grim, seedy versions of Gotham and Batman updated the character's identity from the campy Adam West version from the 1960s Batman TV series, and proved critically and commercially successful enough that a new wave of "dark" superheroes were either created or re-popularized, and preexisting heroes were redesigned or retooled to fit this new trend.[citation needed]
