ICANN, the governing body for the Internet’s naming conventions, recently approved the triple-X domain name, which will host adult content. Ballard Spahr’s Mercedes K. Tunstall says the domain name’s launch is causing concern among those within the porn industry about trademark infringement. According to Ms. Tunstall, “.XXX” was okayed earlier than expected because ICM Registries sponsored it, and ICM, meanwhile, is taking hits from those in the adult industry for being ‘anticompetitive.’ She says her finance-industry clients are worried that search engines won’t have the ability to filter out the .XXX domain, causing embarrassing names with similarities to her clients’ to pop up.
