We posit the following hypothesis regarding the circulation of news in the public space. With the advent of new digital technologies, the public space has split into two distinct yet deeply intertwined social and technological spaces. On the one hand, there is the traditional media arena mostly composed of journalists and politicians, which is still the place for defining public issues and the public agenda. On the other hand, the average citizen may or may not decide to share and comment on news stories on social media. In the former model, the agenda-setting role of media was essential to the framing of public opinion. With social media, each individual can easily select his or her own source of information. In turn, his choices may influence his greater circle of friends. We present the following fundamental question: How and in what way is Facebook reshaping news that the general public is exposed to? The US elections and the English Brexit have recently demonstrated how critical the question of news and misinformation circulation is for the sake of democracy. In this project we will measure two types of audiences for every French news outlet during the recent French presidential and legislative elections. Audiences refer to both the number of visits to a media outlet’s website and shares on Facebook. The Facebook URL Shares dataset will also offer the unique opportunity to examine the properties of news stories that stimulate conversation on social media.
