 What was the first ever dot com domain? Symbolics Inc. registered on the World Wide Web as Symbolics.com on March 15, 1985. Nordu.net was technically the first domain name ever, but didn't go through the registration process. In fact, less than 15,000 domains had been registered to the web in 1992. There were 359.8 million registered domain names at the close of 2019. But no domain name is going to come close to dethroning.com anytime soon, if ever. Regardless, Symbolics.com will hold its place in history. And now you know!
