A jingle is a short, catchy tune or phrase used in advertising to promote a product or brand. It often features simple melodies and repetitive lyrics, making it easy for listeners to remember. Jingles are designed to create a positive association with the product, encouraging consumers to recall the brand when making purchasing decisions. Jingles are commonly used in television and radio commercials, as well as in film and online media. They can enhance brand recognition and help differentiate a product from its competitors. Famous examples include the McDonald's "I'm Lovin' It" and the Kit Kat "Give Me a Break" jingles.
