Meme was coined by Richard Dawkins in The Selfish Gene in 1976, and defined as the equivalent of a gene but for more abstract ideas (because the gene is ultimately just a unit of information as well). I don't remember for sure if religion is specifically an example he personally used, but if it's not it's very comfortably in the same vein.
Which internet meme, if somehow erased from ever emerging, might have the biggest impact?
Is there a fundamental internet meme that has had such a major impact that it would have notable repercussions if it had somehow disappeared?
