Will normal radio give way to internet radio?
Most of it probably will, eventually. Internet radio already offers vastly more choice and flexibility, its sound quality improves all the time while normal radio’s stands still, and the price of internet access (both at home and on the move) is constantly falling. Thanks to the combination of fast internet connections and processing power on smartphones it has become portable. In a decade or two’s time there will be very few (if any) reasons to choose normal radio instead of the internet variety, and stop-gap services like DAB and Visual Radio probably won’t be needed, at least in their current form.
If internet radio does become established, and it uses the a Visual Radio-style track selling system, it could turn radio from a passive activity into a trip through new music, a mixture of exploration and shopping. DJs and their choice of music would become more important than ever.
