Businesses need any form of advertisements whether is print, the Internet, promotional items, TV, radio, words of mouth, etc to raise awareness, to sell or to whatever purpose. Just like you, I have nothing against advertisements but I definitely against FALSE advertisements.
Well, I guess people are programmed to consume so sometimes we can't spot false adverts.
Well, that, and some advertisements throw some pseudo-scientific terminology in, that most people can't spot. But as long as things sound good ...
Yeah I know what you mean @lunanightshade. It's all the psychological/emotional effects that some ads bring to people.
