United States
Overview
American companies overwhelmingly prefer .com, which has left the United States country code in an unusual position: large by absolute count at roughly 1.8 million domains, yet marginal relative to the size of the market it represents. GoDaddy Registry operates it under NTIA authorization. A nexus requirement applies, restricting registration to US citizens, residents, and organizations. Heaviest use comes from state and local government bodies, regional businesses, and URL shorteners exploiting the short string.
