Digital radio might be the next wave, but it might not be as straightforward as simply shoving us all on to DAB. Or so new research from the Broadcasting Commission of Ireland tells us.Despite the shift towards digital in most areas of our lives, FM radio isn’t going away any time soon, the research says. In fact, more than 70 per cent of people questioned for the study said they believes FM radio will still be around in 2020.Commercial radio operators also believe that DAB+ – and not DAB – would be a better choice for broadcasting their digital radio services.And (surprise) one of the problems facing digital radio is a lack of investment. Another is a lack of an industry-wide strategy.Full story is here.In today’s Technology & Innovation section, Jason Walsh asks if the medium has a future. He quotes Today FM chairman Willie O’Reilly as saying that while the digital switchover is welcome, the equipment needs to be in iPods, car radios etc. Which is a fair point – there’s no point switching off analogue services if the majority of people aren’t able to access them easily.There’s also the competing standards to consider, and the sound quality to take into account.
