On March 18 2011, ICANN’s board approved the execution of the registry agreement with ICM for the .XXX sponsored top level domain.
After more than seven years of political wrangling, delays, and policy reversals, the Internet Corporation for Assigned Names and Numbers, or ICANN, gave what appears to be final approval to the controversial .xxx domain. The domains could start appearing within a few months.
ICM Registry is already taking preregistrations for .xxx domains. There’s also a process for companies not in the porn business to purchase domains during a “sunrise” period–those will be set aside as reserved and not available for anyone to use.
This .XXX domain is suitable to promote porn website, however some country which doesn’t allow pornographic can easily block all .XXX contents to appear on their region of users.
