The .Co domain extenstion is off to a great start with support from a lot of major players in the industry. Twitter adopted T.Co for their new url shortener service, while NBC.co is already in place and protecting their brand name. It is rumoured that Google will be the proud owner of g.co soon. Although companies were offered a the chance to register their trade marked names before the general public could get their hands on them, many companies such as Myspace missed the boat and ended up having to pay $25,000 for Myspace.co in the after market (instead of $300).

Below is a list of .CO domain names that have sold for several thousand dollars. This is by no means a complete or updated list. For more sales you may want to check out DNJournal who regularly monitors and list domain sales.
