In the 19th Century, new Court genres appeared to represent trials, which became public after the Revolution. Since 1825 when the first Court newspaper the Gazette des tribunaux was created, the popularization through the media of the Court became more and more successful, first in political newspapers, then later at the end of the century in cheap newspapers and in 1887 when the Court Press Union was founded. The newspaper genre is based on two prototypes: the stenographic report of the Crown Court and the comic little chronicle for the debates of the magistrate’s Court. They contained literary qualities, which were developed during the century in some changes of the article, which enriched her poetics. A specializedpress, which was not daily, entitled L’Audience (1839) or Le Tribunal illustré (1879) turned out to be very innovative. But other genres were also influential: the “ cause célèbre du jour” was a media chain between a “fait divers” and a report created during resounding trials; the new “ Court chronicle “ of the 1880s appeared between a review and a report and some columns like « les souvenirs judiciaires » were situated between History and Fiction. Finally, when the literary, media, and Court fields met, it created the « court fictions », in which trial was at the same time the main subject and the structure. We find them in different fields: in panoramic literature, in novels and also in plays.
