A jingle is a short, catchy tune or phrase used in advertising to promote a product or brand. These musical snippets are designed to be memorable, making it easier for consumers to recall the product when making purchasing decisions. Jingles often incorporate simple melodies and rhymes, which help them stick in people's minds. Typically, jingles are used in television and radio commercials, but they can also be found in online ads and social media campaigns. Famous examples include the McDonald's "I'm Lovin' It" and the Kit Kat "Give Me a Break" jingles, which have become iconic in popular culture.
