Infomercials can be very effective marketing tools. They are long enough to demonstrate the value of a certain product. They offer more value for your money by setting and managing consumer expectations. They also offer consumers money back guarantees, which removes any risk a consumer might feel when they buy the product. Infomercials also demonstrate a product's full use. However, infomercials are beginning to decrease the credibility of products. Bad acting combined with the increase in consumer involvement has begun to make infomercials seem like jokes.
