According to this list of the oldest 100, symbolics.com is the oldest .com domain name, registered all the way back in March in 1985 (I can’t currently get to their site). BBN.com is the next one on the list, over a month later. There was a total of six domains that were registered in 1985, and then a bunch of the big players hit in 1986 (Xerox, HP, Sun, Intel, IBM, GE, and AT&T, just to name a few). An interesting history lesson, indeed.
