Companies, like Nike, Pepsi, coca coala, corona, budlight, gatorade, Mc'donalds spend billions on advertising because it works.....people repeat what other people say, and other poeple repeat what they here on radio and tv commercials 100 time per day....
You won't know untill you try it...These companies spend billions on advertising.....these underground labs just have a few posters with O.C.D.....so how much more research do you think you need to do???
There have been studies done....if you so kids a picture of Ronald Mcdonald from 100's of different countries around the world...they will recognize him...you so them a picture of Jesus....they won't....this isn't to take away from the popularity of Jesus....but just to show you how powerfull advertising is....try Novotropin and Blue tops and then you will know...
