"But Bezos’ move—and even the potential purchase of newspapers by the Koch brothers—is close enough for a 21st-century media landscape. These transactions should be seen not so much as the end of an era, but as a necessary recycling of control. A business that’s always somewhat depended on bigwigs more interested in challenge and prestige than pure profit maximization is naturally going to need some new bigwigs once in a while. It’s the circle of life."
