No. 37 - Ghislain Thibault – Celestial Posters: Skywriting and the Folk Theory of Media Influence Working Papers On January 1st 2016, a few months before the United States presidential elections, spectators at an annual parade in Pasenada, CA suddenly had their attention pulled to the sky. They watched as hundred-foot-tall letters were drawn there with white puffs of smoke to form a series of short sentences, including: “America is great,” “Trump is disgusting,” and “Anybody but Trump.” Readable for only a few minutes, the sentences soon vanished into thin air. The commissioner of the communication stunt, millionaire Stan Pate (a supporter of Marc Rubio), had chosen a technique known in the skywriting industry as “digital skywrit- ing” to intervene in the Republican primary, making use of the sky as a space of mass com- munication.
