The domain name com is a top-level domain (TLD) in the Domain Name System of the Internet. Its name is derived from the word commercial, indicating its original intended purpose for domains registered by commercial organizations. Later, the domain opened for general purposes.
The domain was originally administered by the United States Department of Defense, but is today operated by Verisign, and remains under ultimate jurisdiction of U.S. law. Verisign Registrations in the .com domain are processed via registrars accredited by ICANN. The registry accepts internationalized domain names.
The domain was one of the original top-level domains (TLDs) in the Internet when the Domain Name System was implemented in January 1985, the others being edu, gov, mil, net, org, and arpa. It has grown into the largest top-level domain.
The domain com was one of the first set of top-level domains when the Domain Name System was first implemented for use on the Internet in January 1985. The domain was administered by the U.S. Department of Defense (DoD), however the department contracted the domain maintenance to SRI International. SRI created DDN-NIC, also known as SRI-NIC, or simply the NIC (Network Information Center), then accessible online with the domain name nic.ddn.mil. Beginning October 1, 1991, an operations contract was awarded to Government Systems Inc. (GSI), which sub-contracted it to Network Solutions Inc. (NSI).
On January 1, 1993, the National Science Foundation assumed responsibility of maintenance, as com was primarily being used for non-defense interests. The NSF contracted operation to Network Solutions (NSI). In 1995, the NSF authorized NSI to begin charging registrants an annual fee, for the first-time since the domain's inception. Initially the fee was US$50 per year, with US$35 going to NSI, and US$15 going to a government fund. New registrations had to pay for the first two years, making the new-domain registration fee US$100. In 1997 the United States Department of Commerce assumed authority over all generic TLDs. It is currently operated by VeriSign, which had acquired Network Solutions. VeriSign later spun off Network Solutions' non-registry functions into a separate company which continues as a registrar. In the English language the domain is often spelled with a leading period and commonly pronounced as dot-com, and has entered common parlance this way.
