Meme (pronounced as meam) is an element of culture whose styles, concepts, and behaviour can be indefinitely imitated. But when we talk about internet meme, it refers to a humorous image or video having a definite style and concept which usually go viral on the internet. The style and the concept of the image stay the same whereas the copy changes.
Meme marketing is a subset of viral marketing which is a practice of using mediums like word of mouth and social media networks to fulfil marketing goals.
It is the practice of using users to promote a brand or product by creating appealing, engaging, and fast-spreading news or content.
