From the laboratory to prime time: science coverage in the main Brazilian TV newscast

We analyse the science and technology news reports covered by the Jornal Nacional, the Brazilian newscast with the largest audience, which is broadcast at prime time on a free-to-air channel. The constructed week methodology was used to compose a sample of 72 newscasts, representative of an entire year (from April 2009 to March 2010): 77 science and technology news reports were thus identified, occupying an average of 7.3% of the newscast's daily broadcasting time, and therefore giving evidence that such matters belong on the JN's agenda. Content analysis has enabled us to observe the following: most reports were focused on announcing research results; the main fields dealt with were medical science and health; the coverage of national research projects ranked highest; researchers and scientific institutes represented the main sources of the news items; scientists were mostly shown in their offices, and as far as interviews are concerned female scientists were a minority. The approach to science was more positive than negative and controversial aspects were scarcely explored.
