Singapore’s administration no longer uses static billboards, preferring modern technology. Solar-battery drones can use their built-in holographic projectors to display the most complex images and video. The content of an ad depends on its location and often changes depending on the gender and age of the targeted person (drones are equipped with image recognition systems). Ignoring this kind of personalised advertising is much more difficult but it is possible to pay a small amount of money to unsubscribe.
These drones don’t only serve commercial purposes — they also help maintain order, notifying the police of any problems or violations.
