Sex.com might be the best for 30 minutes but you never hear what Casino.com / Games.com would sell for if listed on the Aucton House.
I personnaly think google.com as a domain is worth the most as it is the one that is the most access in 1 day.
What about 1-letter .coms like a.com or t.com? I have never heard of one being sold, nor have I ever seen a site on one. Are they used at all? I would think they would be expensive since LLL.coms are selling for so much, why wouldn't L.com sell for more?
I would say exxonmobil.com, since it would cost you $490.7 Billion to buy the company to get the name. Google.com would be around $220 Billion to buy the company to get the name...
X.com - Paypal Z.com - Nissan If any of those 1 letter names sold, it'd sell at least in the $x,xxx,xxx range
Sex.com went for 20 mil plus after a long court battle over actual ownership. Same guy who owns sex.com also owned sex.net and sold it last year. He's from the north side of Chicago..
