.org (organization) is a generic top-level domain (gTLD) used in the Internet's Domain Name System.
.org was one of the original top-level domains, established in January 1985, originally intended for use by organizations that did not meet the requirements for other gTLDs. The MITRE Corporation was the first group to register a .org domain with mitre.org in July of 1985.
Now anyone can register a .org domain. .org was the domain commonly recommended for use by individuals.
The .org TLD has been operated since January 1, 2003 by Public Interest Registry.
