Colombia
Overview
Colombia's country code found its largest audience outside Colombia. Delegated in 1991 and operated by .CO Internet S.A.S., the extension was marketed internationally as a two-letter stand-in for .com, and the resemblance to the word 'company' did the rest. Roughly 2.5 million domains are registered, a substantial share of them held by startups and technology firms with no Colombian connection. No eligibility rules apply, and applicants from any country may register.
