Good. We're on the same page then. Snarky response not required but okay.
> Yes. It's called word-of-mouth and it is how it has always been done.
I don't know where to start with how to respond, but I'll bite:
Let's magically go back to the gold rush in the US. You're traveling from New York and arrive in San Francisco. You know nothing about products and services in that market. You walk into town and look for a general good store to buy some water. You ask a guy on the corner where the general store is and so you find the general store based on his help. Okay, so word of mouth. You want to prospect some gold and know you need to buy a pan. There are two gold prospecting material vendors in town, Gold Supply Inc and Acme Gold (but you don't know this because you're new to town). You walk through town looking for a vendor and notice a guy with a megaphone is yelling to the crowd about Gold Supply Inc offering better prices on pans. He is paid by Gold Supply to do this. This is marketing/advertising.
So, no, this is not "how it's always been done" and its inconceivable to think any modern company doesn't spend money on advertising/marketing. I understand the grievances about having hundreds of thousands of megaphones in your face 24/7, but let's stop pretending the world's marketplaces can operate efficiently on word of mouth alone because that's what you're implying.
