In Q2, commercial radio had regained audience share from the BBC, to 42.7%, from 41.6% in Q1.
The fall in commercial radio's share was driven by a surprising drop in local commercial radio's audience. Its share declined to 31.6% in Q3, down from 32% a year earlier and 31.9% in Q2.
National commercial radio's audience share was broadly flat: up 0.1 percentage points from Q2 and down by the same amount from Q3 2008.
The Rajars show radio listening via all digital platforms increased 14% year on year to 21.1% of all listening hours. DAB's share in Q3 was 13.3%, up from 11.3% in Q3 2008. Internet listening, by comparison, was 2.2%, the same level as Q3 2008.
Radio listening via mobile phones continues to grow: 6.9 million adults claimed to do so in Q3, up from 6.4 million Q3 2008. The 15 to 24-year-old demographic shows a slightly bigger increase of 8.3% year on year, with nearly a third of those in this age group saying they have listened to the radio in this way.
The Q3 Rajar period covers the three months to 20 September.
