In 1895, a young Italian named Gugliemo Marconi invented what he called “the wireless telegraph” while experimenting in his parents’ attic. He used radio waves to transmit Morse code and the instrument he used became known as the radio.

Today we understand that technology as sound communication by radio waves, usually through the transmission of music, news, and other types of programs from single broadcast stations. More simply put….Radio works by transmitting and receiving electromagnetic waves.

Radio stations will be allowed to continue broadcasting via analogue for another decade.

The world’s first ever internet radio station was launched by Carl Malmud in 1993. Internet radio involves streaming media, presenting listeners with a continuous stream of audio that typically cannot be paused or replayed, much like traditional broadcast media. Online radio is either pre-recorded MP3 files or live, via-a-microphone broadcasts that are streamed over the Internet.

The radio signal is not transmitted via AM or FM, but streamed via the internet. This means that your device needs to be connected to the internet to receive the radio station. With online radio, you are not limited to one geographic area or dependent upon syndication partners picking up your show in order for it to be heard. It can be heard all over the world.

A technology called PODCAST is erupting all over the internet. Podcasts are digital audio content distributed over the internet using a podcast hosting service. These services store all podcast episodes in one location and automate the generation of RSS feeds. These feeds list all the podcaster’s episodes. Podcasts are not RADIO broadcasts.
