Internet radio is an automated service transferred via the Internet. It refers to any media being webcasted and cannot be replayed, much like traditional radio. While traditional radio is limited by the short range that it is broadcasted and in sound quality, internet radio allows anyone to listen to virtually any broadcast around the world. This new technology is becoming increasingly popular for a society that does more and more on the web. While various models are used, people use stations like Pandora and Grooveshark to play artists that interest them and also to discover new music. Many internet radio sites use complex algorithms and characteristics of musical songs and genres to personalize the stations they have, and some have the option for the user to customize their station by creating playlists. Many sporting events and talk shows are also being streamed online as well. FM stations have also started streaming online to broaden their audience range and to keep up with the increasing popularity of other internet stations. Although FM radio offers convenience and accessibility and streaming online helps them to compete with so many other stations, Internet radio is often favored because of variation, ease of access, and sound quality. Most models of internet radio are like FM radio stations, which have cater to their audiences and advertisers for years. They use advertisements between songs or on their site to pay for the licenses necessary to stream music, but have to pay more in royalties than terrestrial stations do. There are devices for internet radio to allow anyone with an Ethernet or Wi-Fi connection to listen to the streamed music, and many internet radio stations have created applications for smart phones such as the Android or iPhone so that users may listen to music on the go. The effects of Internet radio are still unraveling, although it has already exponentially increased in the amount of popularity, providers, listeners, and music available online.
