Does pouring advertising money into a new product do more harm than good in a market where the product or service is only a 'fad' or? and if no ,why?

"Necessity is the mother of invention" Declaration of success entails expenses and advertising considered as a thumbnail of the institution and the reality of Mentgeltha and I considered it a fad to fad that if what you take the institution erosion lose their money

Advertising spends/budget is always a good investment for a company/brand. Regardless if it's just a fad, I always believe in the saying : Strike while the iron is hot.
