On March 15, 1985, Feinler's Network Information Center team registered symbolics.com, the first commercial domain name ever recorded.
On March 15, 1985, the team led by Elizabeth Feinler at SRI International's Network Information Center registered symbolics.com for the Massachusetts computer manufacturer Symbolics, Inc. This event is recognized as the registration of the first commercial domain name in internet history — a landmark moment in the commercialization of what had begun as a military and academic research network.
At the time, the significance of this registration was not widely appreciated. The .com top-level domain, part of the naming hierarchy Feinler's team had helped design, was intended simply as one category among several (alongside .edu, .gov, .mil, .org, and .net) to organize the still-small population of networked institutions. Few could have predicted that this single registration would presage the explosive growth of commercial internet activity that would define the following decades.
Feinler's group at the NIC was directly responsible for administering these early domain registrations, working out the practical mechanics of how the naming system would function as adoption grew. The registration of symbolics.com stands as a symbolic bridge between the internet's origins as a defense and research tool and its future as a global commercial marketplace.
This milestone is now celebrated annually in internet history circles and is frequently cited as a foundational moment, underscoring Feinler's direct, hands-on role in creating the infrastructure — including domain naming conventions — that underlies virtually all modern web addresses.
