What was the name of the first .com domain name ever registered?

The first .com domain name ever registered was Symbolics.com. It was registered by Symbolics, Inc., a Massachusetts computer company, on March 15, 1985.

Symbolics developed Lisp workstations and software, and its registration marked the beginning of the .com namespace. The domain was among the earliest registered commercial addresses at a time when the Internet was still primarily used by universities, government agencies, and research institutions.

Symbolics.com outlasted the company that originally registered it. Symbolics, Inc. ceased operations in the 1990s, and the domain was sold in 2009. It remains notable as the oldest registered .com domain and is still associated with Internet history.

The names in the wrong options—Apple, Microsoft, and IBM—became hugely important technology domains, but none was the first .com registration. Their registrations came later.
