MASS MEDIA AROUND THE WORLD
There are different types of mass media and some work better than others in different situations. They could be as advanced as digital billboards, or as simple as public loudspeakers.
Digital billboards
Unlike a traditional billboard which can only show one printed image, a digital billboard can change between different messages. Digital billboards are also considered more attractive than traditional ones, and people are more likely to notice them. Moreover, they can also be updated in real time.
Nowadays, digital billboards are common in many big cities around the world. It is hard to imagine places like Times Square in New York, Piccadilly Circus in London, or Shibuya in Tokyo without bright light adverts. Although they are growing in popularity, there have been concerns about their impact on the surrounding environment. Global light pollution is increasing each year. The constant light emitted by digital billboards often confuses birds, harms insects, and causes health problems in humans, too.
Public loudspeakers
In the past, public loudspeakers were used during the war to warn people of air attacks. Nowadays, they are still used in parts of Japan, the Philippines, and the US to alert people to natural disasters such as storms, earthquakes, and tornadoes. In Viet Nam, they are used to communicate important public announcements to residents. However, the noise from a city-wide loudspeaker system can be a problem to some people.
