Batman
The first Batman story, "The Case of the Chemical Syndicate", was published in "Detective Comics" #27 (May 1939). Finger said, "Batman was originally written in the style of the pulps", and this influence was evident with Batman showing little remorse over killing or maiming criminals. Batman proved a hit character, and he received his own solo title in 1940 while continuing to star in "Detective Comics". By that time, Detective Comics was the top-selling and most influential publisher in the industry; Batman and the company's other major hero, Superman, were the cornerstones of the company's success. The two characters were featured side-by-side as the stars of "World's Finest Comics", which was originally titled "World's Best Comics" when it debuted in fall 1940. Creators including Jerry Robinson and Dick Sprang also worked on the strips during this period.
Batman (comic book)
DC Comics relaunched "Batman" with issue #1 in September 2011, written by Scott Snyder and drawn by Greg Capullo, as part of DC's company-wide title relaunch, The New 52. As with all of the books associated with the DC relaunch, Bruce Wayne appears to be about five years younger than the previous incarnation of the character. Superheroes at large have appeared only in the past five years, and are viewed with, at best, suspicion, and, at worst, outright hostility. All of the characters that have served as Robin, except Stephanie Brown, have been accounted for as still having served at Batman's side in the new continuity. The stories build on recent developments, with most of the character's previous history remaining intact, and Bruce Wayne is again the only Batman, with Dick Grayson having returned to his role as Nightwing.
