.XXX has been approved.
A few days ago,
ICANN -- the quasi-government corporation that oversees the internet’s naming and numbering system, approved the .XXX top level domain. .XXX will operate much like .COM does now -- meaning it will be a domain name people can type into their browsers to take them to a website -- but similar to the way .GOV is reserved for governmental organizations, .XXX will be reserved for pornographic or adult content websites.
Current expectations are that .XXX will be available for purchase and use by year’s end.
