I have pretty much every meaningful one word .com domain name listed in my Domain Monitor tool from DomainTools. When one of these domain names transfers to a different registrar, changes hands, or has some sort of other update, I am frequently able to see this within a day or two. I regularly notice great brand match .com domain names that were acquired by the most obvious end user buyer.
I recently noticed that Extend.com was acquired by a company called Extend. Obviously, a company called Extend is better off owning Extend.com, and having this brand match domain name should pay dividends for this company for years to come.
