Virgin Radio is to return to the UK airwaves, along with two spin-off TalkSport stations and a host of new nationwide broadcasters as part of a new wave of digital radio stations. The rock and pop music brand owned by Richard Branson is one of 14 stations that will launch on Sound Digital, the second national commercial digital platform licensed by media regulator Ofcom on Friday. The new stations are expected to launch in March next year and will see around a doubling of today's national digital stations.
