Abstract
In 1896, the year in which Porfirio Díaz was headed for his fourth reelection, there was a notable change in Mexican journalism: a government subsidy allowed the emergence of what was to be its official organ, El Imparcial. The launch of this newspaper, with which the press became the business of industrialists instead of artisans, brought a new, eminently commercial notion of journalism, a new format, and new technologies that increased production and lowered prices; this in turn caused the ruin of such long-standing newspapers as El Siglo XIX and El Monitor Republicano.
