Symbolics registered Symbolics.com, the first commercial .com domain, on March 15, 1985.
Symbolics was a computer company based in Massachusetts that produced specialized Lisp machines. Its domain registration helped establish the .com naming space before the World Wide Web became widely used.
The domain belonged to Symbolics for many years and later changed hands. In 2009, domain investor XF.com Investments acquired it, and it was subsequently sold to its current owner. This history is why Symbolics.com is often discussed in accounts of early Internet commerce.
A common mix-up is confusing the first .com domain with the first registered domain of any kind. Symbolics.com was the first .com, while other domain-name milestones involved different top-level domains and later dates.
