“Radio listening in this country remains high. Nine out of every 10 people listen, mostly through radios but, increasingly, through satellite television, computers, phones. You may have stumped up £100 to buy a digital radio three years ago, but a decade from now, that radio is going to be an antique. Programmes will still be coming out of it and you will still look fondly on its familiar face but, as today’s digital dawn becomes tomorrow’s digital day, be prepared for climate change.”
