.BIZ

This top level domain (TLD) is short for business. Because of the exponential registration of .com domains, the .BIZ extension was created to supplement businesses needing a domain that is no longer available as a .COM. Because the .COM TLD is still the most sought after domain extention, .BIZ domain names are still widely available.
