Open innovation has a strong foothold in the tech industry. Big tech companies create application programing interfaces, or APIs, to tap into the knowledge base of outside software developers. By doing this, centralized companies are able to access external pools of knowledge that enhance the value of their own proprietary application. One prominent such example is Facebook’s ‘Like’ button API. Facebook made integrating the ‘Like’ free and easy because it let them tap into apps’ users, giving them access to massive data they didn’t have access to before.
