In anattempt to answer it, this dissertation covers the history of journalism, in order to identifythe social contexts in which significant changes occurred, and how each step left ideas ormodus operandi found today in the dissemination of disinformation. The theoreticalframework of the study includes the theoretical approach of the context of ICT, social mediaand fake news itself, in the light of authors from the human and social sciences, in the fieldsof sociology, anthropology and philosophy, which allow addressing aspects and dimensions complementary to the studied phenomenon. In addition, a mixed methodology research was carried out, through a survey andinterviews with experts on the subject.
