Mediación periodística, circulación digital y persistencia del acontecimiento en la esfera pública

Abstract

This article examines how journalistic mediation and digital circulation contribute to the unequal persistence of two recent institutional attacks: the storming of the United States Capitol on January 6, 2021, and the invasion of Brazil’s Three Powers headquarters on January 8, 2023. The design combines annual Google Trends series with contextual triangulation based on moments of journalistic and institutional reactivation and on secondary public opinion data produced by Pew Research Center and DataSenado. The results show that the Brazilian case concentrated higher and more volatile initial intensity, whereas the U.S. case displayed longer persistence. The article argues that the public duration of the event depends less on the original shock than on the capacity of journalism, platforms and institutions to reopen it narratively as a public problem.
