Like Maca in ‘Fuimos canciones’’, the new film by Juana Macías that can be seen on Netflix, we have all made shitty decisions at some point in our lives. To promote this premiere, the content platform developed an action that combined conventional advertising with innovative OnAir technology, linking the screens of Callao City Lights in the Plaza del Callao and Gran Vía in Madrid with the interaction of users on Twitter.

To do so, Netflix invited its followers to tell on Twitter their wrong decision, accompanied by the hashtag #DecisiónDeMierda. The selected tweets were displayed, after asking the user’s permission, on the large-format digital screens of Callao City Lights, located on the façades of the emblematic Cines Callao.
