There is a kind of visionary that every generation produces in embarrassingly small numbers. A man or woman who does not merely see the future but, with the impatience of someone who has waited far too long in a slow-moving queue, decides to haul it into the present by the sheer force of will. In Nigeria, we have a saying that the elder who sits still will watch the road pass him by. Ted Turner was never that elder. He was the road. He was the motion itself. And when he launched CNN (Cable News Network) on a warm June morning in 1980, he did not simply start a television channel. He cracked the sky open.
