"Textbook publishers don't even bother to advertise at their conventions"

This quote by Peter Brimelow recommends that textbook publishers are not actively promoting their products at conventions. This could be analyzed in a few methods. To start with, it might mean that book publishers are not seeing the value in going to conventions and are not investing in promoting their items. It could likewise indicate that book publishers are not seeing the need to market their items at conventions, as they are already popular and developed in the industry. Finally, it might imply that textbook publishers are not seeing the capacity for increased sales at conventions, and are instead focusing their efforts elsewhere. Whatever the factor, it appears that textbook publishers are not actively promoting their products at conventions.
