As I understand it - its pretty easy to add subliminal messages (message) to videos with sound. All one needs to do is make the sound level of the main video higher than the sound of the message. Care of the message sound level must be very, very low wherein one can barely hear it.
What are your opinions about the ethics and reputation? Personally, I would not buy anything if I knew it had a message and I would stomp on any internet marketer that does it.
Do you know of any IMers that do it? Just a yes or no is fine. No names.
Some people on youtube advocate it in the sense of positive messages such as weight loss. Then there is the opposite being negative messages such as the college student sending mom an entertaining video from campus with the message "send money" lol.
