A survey in 2002 showed just 1.8 percent of people listened to radio on mobile devices throughout Great Britain. Increase use and upgrade the technology, and now that number has increased seven-fold. A survey by England’s Radio Joint Audience Research (Rajar) shows 13.5 percent of all people surveyed said they had used their mobiles for radio listening in the third quarter of this year. In the 15-24 age category, nearly one-in-three, 32.7 percent, used mobile devices to tune in radio, up from 6%, seven years ago. The same survey found digital radio listening was on the rise. DAB listening was 21.1 percent of the overall audience in the third quarter of 2009, an increase from 18.7 percent one year ago, and nearly one-in-three surveyed said they owned a DAB radio set at home.
