Internet Domain Extensions were generally assigned by country

From $0 to $1 Billion  in less than a lifetime

New domain registrars are approved frequently

Look down through the extensions.  Many are meaningful within industry.  Although many associated with ICANN are "not-for-profit" organizations, some of the Domain Registrars are very profitable (i.e. Bob Parsons, GoDaddy).  Also, more extensions will be defined, yet with those we have, these abbreviations have special value.  Think about the Periodic Table of Elements and how each element has an industry around it.

Internet Corporation for Assigned Names and Numbers (ICANN)- accredited registrars have the authority to assign domain names for the top-level domains (TLDs) of .com, .biz. .info, .name, .net, and .org

ICANN's working group, Country Code Names Supporting Organization (ccNSO),  generally followed the accepted abbreviation of that country's name within the Universal Postal Union.¹ Yet, this determination was not always consistent. Many exceptions were made and new extensions introduced.
