Google has purchased the shortest possible domain name to make it easier for Chinese users to find Google: g.cn. Interestingly, "g.com," along with most other single-letter and single-digit domain names are reserved by the Internet Assigned Numbers Authority. The IANA is the master arbiter of domain names and addresses on the Internet. There are a few one-letter domain names out there, though: Z.com is owned by Nissan, Q.com by Qwest, and X.com is owned by PayPal. There was a proposal floated a few years ago to auction off the one-letter domain names, but nothing has come of it.
