In German, the testimonial can also be a promotional person who is in favour of a brand or product (“advertising ambassador”), for example for the quality and usefulness and/or price quality of a product. It can be a real person (living or dead) or a fictional figure (advertising character). Typical testimonials are celebrities, experts, collaborators or stylized users.  Fictitious testimonies known in the German-speaking region are or were the insurance agent Mr. Kaiser and Clementine. Attention is not enough. The sharp vulgar credo of the American marketing gurus for the beginning fart to start (German and in essence: a noisy fart at the beginning guarantees the attention of the public) disappears without solid editorial support. The great-grandmother are the TV spots for the detergent Ariel with the iconic advertising character Clementine.
