Analogue broadcasting

Today we live in the era of free music, news and chat programmes. However before Internet appeared nothing had competed to radio, not even television.

The radio is actually a tool in which electronic components absorb the airborne radiowaves and then transform them into tones that can be perceived by human ears. Radio was developed in the late 19th century and reached the peak of its popularity decades later. While it is not as popular as once was, wireless communication is still the basis of the achievements of the modern age: wireless internet, cell phones, RFID (radio frequency identification) chips, etc.
