Colgate-Palmolive Co. produced a television advertisement that dramatically demonstrated the effectiveness of its Rapid Shave shaving cream. The ad purported to show the shaving cream being used to shave sandpaper. But because actual sandpaper appeared on television to be regular colored paper, Colgate substituted a sheet of Plexiglas with sand sprinkled on it. The FTC brought an action against Colgate, claiming that Colgate’s ad was deceptive. Colgate defended on the ground that the consumer was merely being shown a representation of the actual test. Explain whether Colgate has engaged in an unfair or deceptive trade practice.
