Lesson: Build better, more desirable products.
IMO, an aggressive ad campaign implies a product that can't stand on its own.
Example: I can't remember the last time I paid attention to an Apple ad. I know which products I want because I know they are quality and I go looking for them.
Pull, not push.
Simply not true. Who do you think makes the most desirable products in the world? Many would say Apple. They still advertise. Heck, a Keynote is nothing more than a type of advertisement. Tesla advertises. Everyone does it no matter how amazing and desirable their product is.
Show me a product that doesn't advertise and I'll show you a company that's missing out on HUGE potential sales.
You may claim not to be swayed by Apple advertisement but more everything on this site is an ad for Apple. It touts the features and provides information for people to use in making a buying decision.
We also have lots of studies that show no matter how much you believe advertising doesn't work on you, you're simply wrong. It works on everyone, no matter how much they swear it doesn't.
