But you seem to think that his techniques differ from what is known as magic.
I do, only because he specifically disclaims himself at the beginning of the show. "I am Derren Brown, throughout this show there are no stooges or actors of any kind. I achieve my feats using a combination of neural-linguistic programming, hypnosis, and advanced language patterns"

That's not exactly what he says, but that's basically it. I don't think anyone would consider it magic anymore, but that's just me. And of course I remember you pointing that out earlier in the thread, but I don't think his intention is to come off as a "magician" due to his disclaimer.
