Back in the day
If you head over to the internet archive, http://web.archive.org , you can see what used to be at that site. Here is the most recent one: http://web.archive.org/web/20020123010736/http://www.santaclaus.com/ and it doesn't look as if it has changed much since 1996. So my guess is that it is pretty irrelevant the company that it is registered to, just some guy's homepage that apple paid a small fee for.
