As of Q1 2008, 31 percent of Britons ages 15 and older listened to the radio via a digital platform every week, including a digital audio broadcast on the radio, cable television or personal computer, according to the Radio Joint Audience Research estimates.

The growing audience also spent more time on digital radio. Weekly listening hours increased nine percent to reach 184 million in the first quarter, and digital radio now makes up 17.8 percent of all radio listening in the UK.

Radio listening via mobile phone also continued growing. In Q1 2008, 11.6 percent of adults ages 15 and older used their mobile phones to listen to radio, up from eight percent in the same period last year, eMarketer reported.

The percentage of 15- to 24-year-olds who listened to mobile radio was up from 20.3 percent in 2007 to 27.3 percent at the end of March 2008.
