4. Porn.com, $9.5 Million
Buyer: MXN Limited
We don't know the exact figures, but we can imagine the number of daily visitors to Porn.com is much higher than even we can estimate. MXN wouldn't release exact numbers when it purchased the adult industry's top domain; it only said that it paid more than $9 million. A writer for Moniker.com, a domain name service, did a little more research and discovered it was sold for a minimum of $9.5 million.
