Stranger Antenna was a stunt made for Netflix’s Stranger Things season 3. It was an app that warmed Brazilian fans up for the third season by giving them the first chance of a sneak peek at unreleased new Stranger Things scenes. This could only be done by mimicking an old national habit, common in the 80s, of putting steel wool on TV antennas to improve the signal. With Stranger Antenna, fans had to put a steel wool pad near their phones in order to tune in to new ST3 scenes and exclusive content created only for the app.
