Back in the day--up until 1995 or so--it used to be free to register domain names. There was this text file that you would edit with your registration and e-mail it to Internic to get your domains. Anyone could get a .com (commercial) but you had to prove that you were a non-profit or a network provider to get the .org and .net suffixes. I registered some really sweet names. I had snell.com, cjs.com, grateful.com, elite.com, and a bunch of others. Then in '95, they started charging $70/year for domains. This was before the days of GoDaddy and $8 registrations. I was a poor college student and couldn't afford $2000 in fees so, like a total idiot, I let all my domains go.
I feel lucky that I still have chrissnell.com, blueaspen.* and island.nu amongst a few others.
