Do remember when OldVersion.com first started? Do you remember viewing OldVersion.com on July 09, 2001?
I can show you a website I found from TechTV (call your local cable or satellite provider if you don't get this channel), it's called Internet Archive. One of their services is the Internet Archive Wayback Machine.
Try other websites too. Example: Take me back to the old days of microsoft.com.
NOTE: The Internet Archive Wayback Machine only goes as far back as 1996.
