Does the radio still have a future in the digital age?

For my EPQ I am going to be researching radio and trying to find out if radio still has a future in the digital age? By doing this I am going to be researching the history of radio, finding out about current stations and pirate radio stations; how social networking effects the radio; hospital and charity radio; the influences DJs have on radio shows and ratings etc; how events run by radio stations effect popularity; alternative ways of accessing music and the development of DAB.
