By 1942, the writers and artists behind the Batman comics had established most of the basic elements of the Batman mythos. In the years following World War II, DC Comics "adopted a postwar editorial direction that increasingly de-emphasized social commentary in favor of lighthearted juvenile fantasy". The impact of this editorial approach was evident in Batman comics of the postwar period; removed from the "bleak and menacing world" of the strips of the early 1940s, Batman was instead portrayed as a respectable citizen and paternal figure that inhabited a "bright and colorful" environment.
