L'Auto-Journal is a bimonthly magazine created in 1950 by Robert Hersant and editor-in-chief Gilles Guérithault, devoted to automobiles. Notable journalists who have worked for l'Auto-Journal include Roland Gaucher and Jean-Marie Balestre. At the end of 1969, L'Auto-Journal abandoned the newspaper-style broadsheet format that it had employed for nearly two decades, in favour of a magazine format. For many years after that the magazine still stood out from the crowd because the pages were longer, by approximately 15%, than those of the standard format used by other magazines.
