I recently got given a flash new phone from work (lg gw525) and it has built in radio.

This isn't exactly 3g stuff but i'm surprised that when i'm listening to radio stations, it not only tells me the name of the station but in many cases, it also tells me the artist and name of the song that's playing.

My question is, how is this data being received? It's not being recieved via the internet because i've done tests!!

Is this data actually being sent via radio? If it is (which it must be) i'm surprised... i only thought radio sent sound waves? Is there a name for this? When did they first start broadcasting this data?

It is data transmission which is interwoven with the FM radio signal.Albeit the data is quite small it is enough to give basic text display on your radio.

Its known as FM-RDS and was used and developed on the Pager transmission system.
effectively the data piggy backs on the FM signal

Ya need to be in the big city to get RDS info. Most radio networks not providing that service in regional areas.
