18. AltaVista.com, $3.25 Million
Buyer: Compaq Computer Corporation
Remember AltaVista? If you've been using the Internet for more than 10 years, you should. Back in the '90s, before Google came through and crushed the game, AV was one of the 'Net's premier search engines. When Digital Equipment Corporate, the company that owned and operated AltaVista, was sold to Compaq, it was decided that AV would be an online portal. There was only one problem: Compaq didn't own the domain name. $3.25 Million later, that was all worked out.
