In the near future, old-fashioned AM/FM radio will be replaced by digital radio, also known as DAB radio (Digital Audio Broadcast). DAB protocol has been in development since the '80s, and now it's making room for the more efficient and comprehensive DAB+. DAB+ utilises AAC audio instead of MPEG-2 audio. Because AAC audio deals with available bandwidth more efficiently, other media such as traffic information, program information and slide shows can also be transmitted via DAB+ protocol
