Editing Justice League (section)

==Cultural impact==
Most of the characters that appear in DC Comics' books are set in the same fictional universe, known as the [[DC Universe]]. They occasionally make guest appearances in each other's solo books, and more regularly in team books such as ''Justice League''. Such crossovers encouraged readers to buy other books in the DC Comics catalogue, and readers became engrossed not just in the individual characters but in their web of relationships across the broader setting, thereby building brand loyalty. [[Marvel Comics]] copied this idea by creating a number of superhero teams of its own, the closest analogue being the [[Avengers (comics)|Avengers]], so as to promote and develop the [[Marvel Universe]]. Some readers focused their attention on just one of these two comic book universes, as they were both large and did not overlap. Thus, the superhero fandom developed sub-communities of DC devotees and Marvel devotees.<ref name=Kaveney2008p28/>
