Education has .edu, .gov belongs to the government, and now, adult entertainment has .xxx.
Starting last week, anyone can go online and buy a domain name ending in .xxx, but it's not all adult entertainment companies that are rushing to purchase the new addresses.
Colleges and other institutions have purchased .xxx domains preemptively to prevent others from doing so and associating their names with adult content. And many big names in the adult entertainment industry are opposed to the possibility of censorship by places that could block the entire .xxx domain.
