The discussion of creating new Generic Top-Level Domains has been around since the inception of ICANN; there was no set number fixed, and the fact that the .com extension has long been the most widely used and recognizable top-level domain was encouraged by ICANN's slow policy development process. It was underwritten in the 2001 amendments to their MoU with the U.S. Department of Commerce that ICANN was to "collaborate on the design, development and testing of a plan for creating a process that will consider the possible expansion of the number of gTLDs".
