DC Comics
In 1970, writer Dennis (“Denny”) O’Neil and artist Neal Adams introduced a new level of maturity to the superhero genre with Green Lantern/Green Arrow. The book, which featured stories that dealt directly with social issues such as race relations, pollution, and drug abuse, is regarded as one of the defining titles of the Bronze Age of comics. O’Neil and Adams also teamed on an influential run of Batman stories, and Adams drew what is widely considered to be the definitive modern version of that character. During that time the DC superhero books—along with many of their books in other genres—were considered to be set in the same fictional universe and shared the same continuity.
