JLA commonly refers to the Justice League of America, DC's flagship superhero team featuring Superman, Batman, Wonder Woman and others. The shorthand became especially familiar to cartoon fans through Justice League, the animated series that ran on Cartoon Network from 2001 to 2004, and its follow-up Justice League Unlimited. Short heroic stings associated with the team have since circulated online as entrance sounds, shared on soundboards and in edits where a group arrival needs instant comic book weight, long after the original series ended.
