In the field of journalism, « new » technologies are helping to dissolve what have long been considered winning formulas. At the same time, and with the help of the same technologies, the interested parties experiment and innovate as they seek new, successful mixes. This text presents three such cases of destructuration- restructuration that have affected journalism in the last decade. The first one concerns new business models that have given rise to transnational all-news television stations, free dailies and Internet. The second involves the reorganization of the content of generalist (catch-all) medias. On one side, publicity, entertainment and information are separated and give rise to distinct media; on the other, hybridation intensifies when they remain together in the same supports. The third restructuration goes to the very heart of journalistic information itself with the dissociation of its various components. : news production (newsmaking) remains in the hands of professional journalists while the editorial function (op-ed) is dispersed through so-called « citizen journalism » on the Internet and journalistic authority restricts itself to creating images of star journalists and commercial brands.
