Podcasting does some disruptive things to the established way of doing broadcast radio. First of all it enables anyone to be a “caster”: no licence, no regulator, no formats. All that’s needed is some basic home computing equipment… Secondly, and even more disruptively, podcasting destroys the broadcast model of appointment making with the programmes: a podcast starts when the listener wants it too, not when scheduled by the broadcaster.
