Porn companies sue ICANN over .XXX domain
Two of the world's biggest porn companies have teamed up to sue the Internet Corporation for Assigned Names and Numbers (ICANN) and ICM Registry over their introduction of the .XXX top-level domain.
Digital Playground and Luxembourg-based Manwin, which owns a network of websites including YouPorn.com and manages Playboy's brand on the web, claim that ICANN and ICM are guilty of antitrust violations.
