The much-derided British city on Milton Keynes is to get a high-speed Wi-Max broadband network. If I understand the technology correctly, it could pose a further threat to traditional media - in particular radio. With some people already installing Mac Mini computers into their car dashboards, the ability to connect to the internet while on the move makes listening to web radio as easy as listening to local radio. With the choice of thousands of channels, will people be necessarily content with what's served up locally? And will the licensing system - under which broadcasters have paid millions of dollars to the government for access to the airwaves - become redundant?
