· Telefónica deployed a technology solution for large-scale events that enabled the 7,000 attendees at Jorge Drexler’s concert at the Movistar Arena to interact with the show in real time and play an active role in the musical experience. · Through a real-time engagement platform, the audience chose the song La trama y el desenlace, which was exceptionally added to the setlist of the artist, recently nominated for eight Latin Grammy® Awards. This pioneering experience enabled concertgoers to play an active role in the show.
