Some critics believe that the very concept of intellectual property is mistaken. Unlike physical property, ideas are non-rivalrous goods that can be used by many people at the same time without making them any less useful. The term 'intellectual property' was widely adopted only in the 1960s, as a way to bundle trademarks, copyrights and patents. Those critics argue that today's rights are too strict and make the sharing of knowledge too expensive. The paradox about intellectual property in IT and telecommunications is that it eases the exchange of technology and acts as a bottleneck for innovation at the same time. The whole system is in a stage of transformation. 'Markets require institutions, and institutions take a long time to develop. Today, the institutions for a 'market for technology' are not well developed, and it is costly to use this market,' says a specialist. Ideas are to the information age what the physical environment was to the industrial one: the raw material of economic progress. Just as pollution or an irresponsible use of property rights threatens land and climate, so an overly stringent system of intellectual-property rights risks holding back technological progress. Disruptive innovation that threatens the existing order must be encouraged, but the need to protect ideas must not be used as an excuse for greed. Finding the fight balance will test the industry, policymakers and the public in the years ahead.
