Listeners can now search hundreds of radio stations and click to hear their favourite artists through a new "one-stop" online platform.
Radioplayer, released yesterday, features about 230 stations, including the BBC and commercial and community stations.
Listeners can search by station, location, topic or artist and can click through to live stations or podcasts. An app version for mobile devices is expected by next year.
However, the Government's ambition of switching from analogue radio to digital has been dented by a fall in sales of DAB digital sets.
