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.
Although com domains were originally intended to designate commercial entities (others such as government agencies or educational institutions have different top-level domains assigned to them), there has been no restriction on who can register com domains since the mid-1990s. With the commercialization and popularization of the Internet, the com domain was opened to the public and quickly became the most common top-level domain for websites, email, and networking. Many companies that flourished in the period from 1997 to 2001, (the time known as the "dot-com bubble") incorporated the com suffix into company names; these became known as dot-coms or dot-com companies. The introduction of biz in 2001, which is restricted to businesses, has had no impact on the popularity of com.
Although companies anywhere in the world can register com domains, many countries have a second-level domain with a similar purpose under their own country code top-level domain (ccTLD), such as Australia (com.au), Sri Lanka (com.lk), Greece (com.gr), Mexico (com.mx), South Korea (co.kr), India (co.in), Indonesia (co.id), China (com.cn), Japan (co.jp), Vietnam (.com.vn) or (.vn) and the United Kingdom (co.uk) are all examples.
Many non-commercial sites and networks use com names to benefit from the perceived recognizability of a com domain. However, the registration statistics show varying popularity over the years.
The U.S. Department of Commerce on November 29, 2012, approved renewal of the .com Registry Agreement between Verisign, Inc., and ICANN. Through this agreement, Verisign will manage the registry for the .com top level domain until November 30, 2018.
