Radio stations have welcomed a delay in announcing a digital switchover date for radio after communications minister Ed Vaizey said the service must be improved further before a commitment can be made. Vaizey unveiled a range of measures aimed at improving access to digital radio, including up to £21m of new investment from the BBC, government and commercial radio to improve digital radio coverage and government funding for Ofcom to develop ways for smaller radio stations to go digital, but he stopped short of announcing a switchover date.
