The domain name Vista.com and the VISTA trademarks were sold by Innuity for $1.25 million. You can read the press release covering the sale here.
Sahar also has some commentary about the sale here. I think Vista.com is a fantastic generic domain name. It illustrates the topic of “domain usage.” Regardless of whether a huge company owns a trademark for the word, someone else can own it as long as the content doesn’t infringe on the other trademark.
