Call what store? How do I know a store even exists to call it? How do I find out the store’s name and phone number? How do I find out where the store is located?

You say products that work tend to get remembered, and sure, for existing products with a market you might be right… people would continue buying those things even with no advertising.

But how did the FIRST person who bought the product find out about it? Someone has to try it once before you can even know the product works. How would a new product enter the market?

Maps exist. Search engines exist. Have you been stuck in a cave the last 50 years?
