Comics in America have broadened their appeal by marketing to adults. Prior to World War I

I , usually only adolescents bought comics. During World War I1, the comic book industry in the United States began to undergo a major change. When the war started, the government subsidized the comics industry in order to take advantage of the powerful propaganda effects, regulating them for purposes of military defense. By the time the war was over, the taste for comic books had reached the adult population. Publishers from this point on expanded this portion of the market that was to become the largest sales increase in the history of the comic industry.

The editor of Exciting Comics, Ed O' Donnell, was important in extending the success of this marketing drive. Here organized comic drawing to encourage artists' innovation. The market had declined slightly since the late forties. O' Donnell, against conventions, hired adroit illustrators. He abandoned the low-cost budget publication, a step considered risky to his peers in the publication industry; however, his begin environment for artistic creation eventually proved successful. Kenny Bar was one of the artists that helped spawn the most innovative titles to come out of Exciting Comics. He insisted on revising the concept of the comic book radically; he proposed to create characters designed to capture markets that had previously not been successfully explored by comic books. This revolutionary idea laid the foundation for the now thriving market for sophisticated adult-oriented comic books.
