What allows an ad to jump from just an ad to something that is virial - is what's called the amplification effect.

The amplification effect is when a $100 ad reaches the same amount of people as a $1000 ad with even more conversions.

Its an effect where the ad gets shared itself and moves through individuals and the public in a way that is seamless.

The way you do this is not by educating or selling a product - you do it by appealing to underlying desires in the customer and guiding them.

The products change but the human desires don't - amplification ($1000 Ads for $100) starts there.
