Advertising jingles are short, catchy tunes or songs created to promote a product or service. They often include memorable lyrics that highlight the benefits of the item being advertised, making it easier for consumers to remember the brand. Jingles are commonly used in television and radio commercials, as well as online advertisements. These musical pieces aim to create a positive association with the brand, encouraging potential customers to make a purchase. Successful jingles can become iconic, sometimes even outlasting the products they promote. Examples of famous jingles include those from McDonald's and Kit Kat.
