A meme is a piece of media, typically humorous in nature, which spreads rapidly online, often through social media platforms. Memes can be images, videos, texts, or a combination of these, and are characterized by their viral nature and cultural relevance. They often contain a satirical or humorous commentary on current events, trends, or behaviors. In digital marketing, memes are used for their high engagement potential and ability to resonate with a wide audience. However, their use requires a deep understanding of the target audience and current internet culture to ensure relevance and effectiveness.
