ICANN has finally approved .xxx as a top-level domain. Unfortunately, according to one article, the strictly volunteer use will never encompass the majority of porn sites because ICN, the group responsible for administering the TLD, is going to impose rules about where and how a porn site may operate. Not only that, but domain names will cost significantly more than .com domain names do today:

The new domain will cost less than $100 and will be available to registrants willing to adhere to the predetermined best business practices.

There will remain countless porn sites in the .com TLD, dramatically reducing any "save the children" benefit that proponents claim the new domain provides.
