Real life propaganda technique 1

In real life, I think that the "Testimonial" propaganda technique is the most commonly used. On television and in magazines celebrity faces are used to sell more of the product, or get it out into the public if it's a new product then the famous faces will get the product out into the public and it will sell faster and more effectively. If just everyday people had to go out onto the streets and have nothing but themselves to sell the product there would be alot less products out on the market today.
