The radio

Radio waves are a natural phenomenon, which lies behind everything from mobile phones and WiFi to remote controls and satellite TV. The ether is filled with invisible messages and you can choose which one you want to capture or send. The first radio stations transmitted Morse Code signals in 1900.

In 1920 the electron tube was developed and there were radio stations with talk and music. In the mid-1900s the transistor arrived and made the radio smaller and lighter.

Today digitalisation characterises development. The new radio and TV laws open up commercially financed terrestrial digital radio. With web radio the concept is released from the technology. The important thing is the transmitted message, not how it reaches the listener.
