.org
The ".org" domain is one of the original top-level domains (TLDs) on the internet, established in 1985. It is primarily used by non-profit organizations, charities, and other groups that aim to serve the public interest. However, anyone can register a ".org" domain, making it a popular choice for various types of websites.
Websites with a ".org" domain often focus on community service, education, and advocacy. Many well-known organizations, such as the Red Cross and Wikipedia, use this TLD to signify their commitment to social causes and provide information to the public.
