Ideas spread like this; mind to the person then person to the mind. Ideas are spread by advertisements by words by people, as I said before.

Ideas are spread by talking, by singing, by dancing, by art. An effective way to spread ideas is to talk to explain to feed someone else’s mind an idea then let the hunger develop. Make their minds hungry for more ideas make their minds hungry, make them want to share your idea, to make other minds hungry to develop more ideas, or just to pass on your own.

Ideas spread through the hunger of their mind, racing and racing trying to find more explanations. Giving your ideas a purpose, your ideas, your mind food. Giving them your mind food.

That everyone, is how ideas spread, that is how an idea implants itself in a brain, making it hungry for more.
