What is web-radio, and what are the benefits of this service?

Web radio, or more commonly referred to as internet radio, is a technology that continuously transmits audio over the internet to your computer. It’s a technique of broadcasting audio using data transmission that is very similar to terrestrial radio, and it’s used by 57 million people every week.
Internet radio broadcasters use “streaming” to transmit their stations over the internet to their users. Listening to audio streams means that you don’t have to download every song and store it on your computer. Instead, your computer downloads small portions of data (usually in the MP3 or AAC formats) in a continuous stream, usually a little faster than you listen to it, and discards the portions once you’ve gone past these parts of the stream. This means that you never have a fully-downloaded file on your computer.

The most obvious benefit of using internet radio is access to thousands of radio stations that you wouldn’t normally be able to listen to due to your location. Another advantage is having an almost unlimited supply of music and live shows that you can listen to in real time.
