Internet Radio

Internet Radio is an audio broadcasting service transmitted via the internet. It started back in 1993 when Carl Malamud launched Internet Talk Radio that was the first computer-radio talk show.

Internet Radio presents a continuous stream of audio to the listeners using a streaming medium. Popular streaming audio formats are MP3, Ogg Vorbis, Windows Media Audio, RealAudio and HE-AAC. The bits are streamed over the network in TCP or UDP packets, then reassembled and played within seconds.

Because it uses the internet, Internet Radio services are accessible from anywhere in the world (as long as internet connection is available).
Internet Radio is becoming popular. In February 21, 2007 a survey of 3,000 Americans released by consultancy Bridge Ratings & Research found that as much as 19% of U.S. consumers aged 12 and older listen to Web-based radio stations.
