This thesis investigates and seeks to answer two research hypotheses: a) The journalism professionals are migrating from traditional media (print, radio and TV) to new media, especially for blogs. b) Journalists have adopted and are migrating to blogs in search of greater autonomy, independence, freedom of expression and professional achievement. The theoretical framework that guided this study conceptualizes the work and communication as a human activity, ergologic (Schwartz), a constituent of the ontology of social being (Marx). The journalistic work is approached from this theoretical framework, to highlight how the production processes in this professional area were transformed by technology, techniques and differentiated organization of productive routines. One takes the classical concept of journalism and its ethics and analyzes its development throughout the twentieth century and early twenty-first in the light of the changes brought about by the globalization, the journalist’s job in the world and the organization of communication companies in the contemporaneity. The humanist values that founded the journalistic field are questioned in relation to the values of the consumer society, information and spectacle. From a methodological point of view, the procedures are: relevant literature to concepts involved and also the empirical case studies and observation of experienced journalists who migrated to blogs as a new career option. As a result, it was found that journalists migrated to the blogs in search of independence, among other reasons, but found obstacles that prevent them from exercising full freedom of expression in the new medium, as the financial restriction and the judicial. They are also looking for new economic arrangements that will allow the full exercise of the profession in blogs.
