The title of this dissertation is Sunday is a happy day. Here i analyse different variables that may contribute to a better understanding of the relationships established between children and the news originating in television. The research as such has an ethnographic bias about children who attend the first year of basic education in a municipal school in Rio de Janeiro, during the 2007 school term. In the core of this study these children are characterized as active and participatory subjects who like to express opinions, who feel the aptitude for questioning certain standards, as shown by television and the world of adults, in interactive situations with their peers. My main objective was to get acquainted and to understand their preferences, their development based on what they watch, their feelings and expectations, and the modes of relationship between their experiences and television news. The analysis involved television news production, broadcasting data and its repercussion in their lives. Thus, children were regarded as culture producers and consumers as well as a critical audience of newscasts. In order to know the attributes of events that might become news on television and at the same time to be able to understand the different repercussions of such news in these childrens lives, the theoretical approach included diverse areas such as Social Communication, Education and Theory of Literature. Those were guided, which was always guided by the possibilities of conceptual limit and range, allowing for the transition from one discipline to another.
