Sometimes advertisers introduce a new product using teaser advertising, which is designed to build curiosity, interest, and/or excitement about a product or brand by talking about it but not actually showing it. They are also often called mystery ads and are also used by marketers to draw attention to upcoming product launches and/or advertising campaigns and generate interest and publicity for them.
