Incidentally I know where you're going here Cranker and your opinion seems to be due to a misunderstanding of what hypnosis is.
It's merely suggestion - it reinforces desired behaviour. It isn't brainwwashing at all - even a hypnotist will tell you that's impossible without using drugs and torture as well.
The psychology behind "suggestion" fits in with hypnosis too. The parts that are "crap" are all things that are misconceptions anyway (that you're in a coma-like trance etc). It's just a more direct way of doing what Marketers do more subtly.
What's this thread about again?
