In The Selfish Gene (1976), Richard Dawkins introduced the word ‘meme’ (derived from the Greek word mimema, roughly translates as ‘something imitated’) to denote “a unit of cultural transmission, or a unit of imitation.”
It turned out to be a good meme itself. Since its introduction, it has spread quickly, and, by now, most people have been exposed to the term somewhere, from newspapers to conversations with friends and relatives to academic publications. In the past few decades, memes have become a field of study.
