This paper aims to update newsworthiness criteria using as referential the social demonstrations that took place in several cities in Brazil in June 2013. It firstly reviews theoretical approaches focused on a broadcasting communication model, from the first studies in the 1960s to the newsmaking in the 1970s. Then, the participation and sharing culture of the early twenty-first century is discussed. Finally, it proposes three news-value definitions consonant with the contemporary scenario of ubiquity and mobile media: hashtag, redundancy and participation.
