Professor Zittrain and I have recently examined a variety of data about registrations in .BIZ. Our major findings are as follows:

At least 74% of currently registered .BIZ domains provide no web content or provide only error messages or placeholders.

Approximately 25% of .BIZ registrations are registered to the same organization that registered the corresponding .COM, and such domains are about one-third less likely to provide substantive web content than domains registered by someone without a corresponding .COM registration.

A large number of .BIZ domains fail to comply with .BIZ registry anti-warehousing policies, suggesting that such policies are not being effectively enforced.

Registrar market shares vary substantially between .BIZ and other TLDs; while the largest .COM, .NET, and .ORG registrars have large shares of .BIZ, certain other registrars also service many .BIZ names.
