It only assumes they are aware that the category of products exists, and ordinary word-of-mouth communication is sufficient to propagate that knowledge.

How does word-of-mouth communication propagate knowledge that is currently in the possession of zero existing customers? Or operate for products that people have little reason to discuss with other people?

Suppose you sell insulation and replacing the insulation in an existing house could save $2 in heating and cooling for each $1 the insulation costs. Most people know that insulation exists, but what causes them to realize that they should be in the market for it when they "already have it"?
