The term meme was coined in Richard Dawkins' 1976 book The Selfish Gene, but Dawkins later distanced himself from the resulting field of study. Analogous to a gene, the meme was conceived as a "unit of culture" (an idea, belief, pattern of behaviour, etc.) which is "hosted" in the minds of one or more individuals, and which can reproduce itself in the sense of jumping from the mind of one person to the mind of another. Thus what would otherwise be regarded as one individual influencing another to adopt a belief is seen as an idea-replicator reproducing itself in a new host.
