Why do just 25 of 35K+ Marketing & Sales books have “Listen” in the title?

The reasons that just 25 of more than 35,000 Marketing & Sales books in the Kindle bookstore have "Listen" in the title:

  1. Marketing has become synonymous with making noise, not listening.
  2. Marketers are still too often measured on activities (i.e. noise), not results. Getting good results means you have to listen to your customers before you start making noise.
  3. The Marketing-Industrial Complex (agencies, software companies, media/publishers, consultants) earns far more money making noise than listening.
  4. Marketing software is better at automating campaigns than listening at scale.

Any other reasons you can think of?
