Tanenbaum notes that Bell Labs’ most significant research and development efforts—transistors, microwave towers, digital transmission, optical fiber, cellular telephone systems—all fit a pattern. They took years to be developed and deployed, and soon became essential parts of the network. Yet many of the essential patents were given away or licensed for a pittance. And those technologies that weren’t shared were duplicated or improved upon by outsiders anyway. And eventually, the results were always the same. All the innovations returned, ferociously, in the form of competition.
