edit: how the heck does a link to an excellent introduction to semiconductor physics get voted down in a thread about an article relating to semiconductor physics?
That site actually does have some decent articles related to semiconductor physics, the whole "Britney Spears" thing is just a gag to show how simple they've made it (though the humor is likely to be appreciated only by Physics geeks :)
My advice if you care about that sort of thing: link in further, e.g., http://britneyspears.ac/lasers.htm
I'm sure there's a less spammy physics site you could have linked to?

Its basically a reverse rickroll. "Britney Spears" was by far the most searched-for term on the internet for a long time.

Although you can't stream that programme and I appreciate that my half-recollections are hardly convincing.
What does seem likely is that the site was in fact set up in the 90s by a physics professor as a joke, and since then it has been used to make money, precisely because it was popular and unusual at the time. Maybe he sold it to someone back in the good old 90s bubble, when men were men and a domain name was a business model.
(Fun Fact: That documentary was presented by the woman who wrote the article about LSD that was on here recently.)
