“Dot what?“, my grandmother asked in '96. Now, you are lucky to find a good six-letter .TV domain.
Back in the day, errr 1980's, you could get some choice dot com names. We came across this list that tells you the oldest domains still registered, a nice piece of trivia:

If contingency domains ever catch on, there will be a whole new race to GoDaddy.com, etc. Here is a good piece on next gen URLs that covers contingency domains and other URL formation techniques.
Enjoy the list, folks!
