aww, I can't enter because mine's not adult.
Record created on 28-Mar-1994.
That actually is my 2nd oldest -- the other one I let go when Notwork Solutions started charging $70 for a two year registration for domains -- it was registered in November 93.
I'm not 100% sure, but, I believe bbn.com is one of the oldest .coms -- having been registered on April 24, 1985. Coincidentally, they also hold AS1 which is a number used for routing packets on the internet.
As for adult, I doubt I have any prior to the ultra* flameout, so, probably November 2000 which was about the time disaster hit.
However, I'll bet everyone can beat the amount of adult affiliate revenue I've made.
Since Nov 2000, I would bet that I have probably made under $100 in adult affiliate revenue.
