From the scream of headlines in newspapers to the silence of home pages in network journalism, front pages and home pages express two moments in journalism. Headlines used to seduce the readers in the streets and were an agent of agenda-setting and social memory. On the other hand, home pages are threatened nowadays by invisibility because of new reading habits: the majority of people are reaching the news through links distributed in social media and search tools, which aren t guided by newsworthiness, but by algorithms. To expose these two moments in journalism, this thesis first maps the begginings of the modern front page in five Brazilian newspapers: Jornal do Brasil, Gazeta de Notícias, O Paiz, Correio do Povo e O Estado de S.Paulo. Then it presents the results of ethnographic studies in two newsrooms - O Globo e O Estado de S. Paulo - and a content analysis comparing the content posted by the three most influential newspapers in the country - Folha de S.Paulo, O Globo e O Estado de S. Paulo - in their Facebook s pages to that published in their front pages. Finally, it presents 26 in-depth interviews with journalists who edit or have edited front pages and home pages. Based on the premise that the crisis of journalism is the result of the crisis of modernity, the purpose was to investigate ruptures and continuities in journalism practices. The results reveal that journalists are worried about the effects of reading fragmentation over agenda-setting and social memory. To reach the public, they are adopting new productive routines, publishing spreadable news on social media, among other practices. On the other hand, they still believe in their social responsability and their role in agenda-setting.
