What method of communication involves using a catchy phrase to promote a brand or candidate?

The method of communication that involves using a catchy phrase to promote a brand or candidate is known as slogans. Slogans are designed to be memorable and convey the essence of a product, service, or political campaign in a concise and appealing way. Their primary function is to create a lasting impression in the minds of the audience, making it easier for them to recall the brand or candidate when needed. Effective slogans often use rhyme, alliteration, or other literary devices to enhance their appeal and ensure that they resonate with the target demographic. By encapsulating a message in a few impactful words, slogans work to establish brand identity and foster emotional connections with potential supporters or customers.
