Ageneric top-level domain TLD intended for domains to be used by businesses; the name is a phonetic spelling of the first syllable of “business.”
It was created to relieve some of the demand for the finite domain names available in the .com top-level domain, and to provide an alternative to businesses whose preferred .com domain name had already been registered by another party.
There are no specific legal or geographic qualifications to register a .biz domain name, except that it must be for “bona fide business or commercial use” (i.e. no personal or “soap box” sites, and no cybersquatting), and the usual legal remedies for trademark infringement are applicable.
It is administered by Neulevel.
