Zombo.com

Zombo.com is a single-serving site that was created in 1998 when Flash animation was a new technology. Originally a faculty and student joke from the George Washington University Center for Professional Development, the site parodies Flash introductory web pages that play while the rest of a site's content loads. Zombo took the concept to a humorous extreme, consisting of one long introductory page that leads to a message that says, "Sign Up For The NewZLetter", with the Z being red.

The website has remained unchanged since its public launch in 1999.
