Specifically, the report indicates that:
- Digital radio services are provided through multiple platforms: digital terrestrial radio, digital television, and through the Internet.
- Coverage varies by service and platform - BBC's digital radio service reaches 94.3% of UK homes (using multiple platforms); commercial digital radio services reach 84.6%; local digital radio services reach 66.6%; 95% of the primary TV sets in UK homes are capable of receiving some digital radio services; and 77% of UK homes have broadband Internet service capable of streaming digital radio services.
- As of June 2012, 29.5% of radio listening was to digital radio services. Roughly two-thirds of that listening was to terrestrial digital radio (DAB) receivers, 15% through digital TV sets, and 13% online.
- Most people still don't own digital radio receivers - less than 30% of radios sold in the last year included a DAB tuner; only a quarter of cars include a DAB tuner; and half of those currently without a DAB receiver said they were not likely to buy one in the next year. Nationally, only 41.2% of people claimed ownership of a DAB receiver, and diffusion varies widely in different regions of the UK (from a high of 54.4% in Surrey to a low of 25.8% in the Scottish Borders).
