This document discusses ten types of "world flatteners" that have contributed to increased globalization. They are: the fall of the Berlin Wall, Netscape, workflow software, open source projects, outsourcing, offshoring, supply chain management, insourcing, information resources like Google, and portable personal devices. Each type is briefly described in one to three sentences.
