Move over .org, here comes .ngo. It's getting a bit crowded in the virtual world, and by next year, non profilt organisations and others could have an exclusive Internet domain. The Public Interest Registry (PIR)-the non-profit that manages and operates the .org domain, has formally submitted its applications to the Internet Corporation for Assigned Names and Numbers (ICANN) for such domains extensions. The .org extension can be used by individuals and for-profit corporations as well, but .ngo will be administered "as a closed domain exclusively for NGOs," says PIR's CEO.
