Le Petit Journal

In 1882, Marinoni took control of the newspaper, succeeding Girardin. As early as 1884, on June 15, the weekly illustrated supplement appeared, first subtitled Sunday Supplement and then the Literary Supplement - of the newspaper, for which an innovation was provided: the color illustration.

This supplement is finally named Le Petit Journal illustrated supplement. Sensing the importance of color, in 1889 Marinoni produced a polychrome printing press, with 20,000 copies per hour, which, from the November 29, 1890 issue, and the portraits of the presidential couple Sadi-Carnot, print in six colors the one and the last page of the illustrated Supplement. The circulation of the Supplement reached one million copies in 1895.
