Gizmodo/BBC, April 5, 2008:

A 43-year-old man from Maryland has sold the domain name pizza.com for almost 10,000 times the price he paid for it. Chris Clark registered the name pizza.com in 1994 for just $20, and continued to pay the annual registration fee until January of this year, when he heard the domain name vodka.com had gone for a massive $3 million, and decided he wanted a slice of the pie.

I won't attempt to calculate the effective ROI on this one, but at any interest rate if you are spending less than $500 total and getting back over 2 million dollars, you are doing well.

I respect this man's discipline. I would have been sorely tempted to auction it years ago, probably for substantially less money. Making even $5,000 off of this investment would have been excellent. At long-term capital gains rates, he will probably clear close to $1.8 of the money. Very well played.
