New Music Seminar Battle for World Supremacy

I've been looking around on the web for sound (or ideally video) of the annual New Music Seminar emcee battles and can't seem to find very much. A lot of dead zshare links, but that's about it. What was the deal with this? Why isn't there more out there about it? Am I looking in the wrong places or using the wrong search terms? A lot of British bullshit keeps coming up instead, because they seem to have coopted the World Supremacy title. Do they have legitimate lineage and I'm just misreading this?
