The first .com domain name

The first .com domain name was symbolics.com. It was registered on March 15 1985, more than 20 years back!
The first domain name to be registered was nordu.net which was registered on January 01 1985.
A list of the first 100 .com domain names is available here | cached copy.
I have also compiled a list of the domain names of the major tech and media companies to see which ones were registered when. IBM.com seems to be the first one in the list (March 19, 1986). Interestingly, both Adobe.com and AMD.com were registered on the same day (17 Nov, 1986).
