Very few people “get it” when it comes to the Art/Science of Marketing. Most people are under the impression that Marketing is Sales on steroids or Public Relations for Products.
My Father was part of the generation that devised Marketing and they were all young guys who went to collage on the GI Bill after WWII. Advertising was where the best and brightest wanted to be. It wasn’t long before these bright Advertising guys figured out that companies were not producing the Products that people wanted to buy, so armed with sales numbers and demographics they created Marketing.
Marketing is mostly research, lots of numbers and analysis in a process of creating new Products that people will buy.
