Bringing an innovation to the market is a process.
Companies, resist new ideas and products, sometimes even kill new products or services and finally accept them only reluctantly.
For instance, television took more than three decades to become a mass medium in the United States—from the first experimental broadcasts in the late 1920s to widespread acceptance in the 1960s.
Companies hostility to innovations becomes stronger when players are interconnected. In a networked market, each participant will switch to a new production process only when it has to. The players’ codependent behavior makes it tougher for companies to dislodge the status quo than if each participant were to act autonomously.
