The comic book "Hellblazer" began in the 1980s and boosted the popularity and image of the occult detective fiction genre and shaped it to its modern form. Many modern examples of the genre such as "Hellboy", "Supernatural", "Grimm", "The Originals", and "The Dresden Files" have been influenced by it, and many imitators of both the series and its character flourished such as "Criminal Macabre", "Gravel", "Planetary", and others. Its elements and style have been used countless of times in other works and many analogues of the cynical protagonist John Constantine have appeared.
