The number of people listening to digital radio services has almost doubled in a year, according to a survey by monitoring group Rajar.
During August and September this year 10.5 per cent of the total radio audience tuned in via digital, compared to 5.9 per cent a year ago.
Of the total audience, 5.5 per cent were using digital radios, 2.9 per cent used digital television, and 1.8 per cent tuned in via the internet, the same split as for 2004.
The number of owners of a DAB receiver, or listeners using digital television or the internet, has increased by a huge 4.7 million or 25 per cent year on year.
Listening via digital radio has also overtaken combined listening via digital TV and the internet for the first time, as those tuning in via DAB jumped by 165 per cent
Last year, people tuning in to radio via traditional AM/FM receivers accounted for 81.8 per cent of the total listening hours. In 2005, this figure fell to 74.8 per cent, against rises for all the digital formats.
However, radio is lagging way behind digital television adoption which now stands at 60 per cent of households. DAB is also rarely used in cars.
