Vox was an Internet blogging service run by Six Apart. Announced on September 21, 2005 by Six Apart president Mena Trott at the DEMO Fall conference under the codename "Project Comet," the site began private alpha testing in March 2006. In June 2006, the site entered public beta—opening registration to outside users on a limited basis via an invitation system—and transitioned to its official name Vox, moving the site to the domain Vox.com. Vox officially launched on October 26, 2006, with registration opened to the general public.
