text: The Justice League, or Justice League of America (JLA), is a group of superheroes appearing in American comic books published by DC Comics. The team first appeared in The Brave and the Bold #28 (March 1960). Writer Gardner Fox conceived the team as a revival of the Justice Society of America, a similar team from DC Comics from the 1940s which had been pulled out of print due to a decline in sales.
  The Justice League is an all-star ensemble cast of established superhero characters from DC Comics' portfolio. Diegetically, these superheroes usually operate independently but occasionally assemble as a team to tackle especially formidable villains. This is in contrast to certain other superhero teams such as the X-Men, whose characters were created specifically to be part of the team, with the team being central to their identity. The cast of the Justice League usually features a few highly popular characters who have their own solo books, such as Superman, Batman, and Wonder Woman, alongside several lesser-known characters who benefit from exposure. The Justice League was created to boost the profiles and sales of said characters through cross-promotion and helped develop the DC Universe as a shared universe, as it is through teams like the Justice League that the setting's characters regularly interact with each other.
  Beyond comic books, the Justice League has been adapted to television shows, films, and video games.
