The trend in innovation has gone to such extent that we see new versions of a product popping up every few months. While the manufacturers claim that each new version has significant improvements well worth the premium price, customer reviews often suggest a different story- a handful of superficial modifications at best.

Examples of frequent innovation include tech products (Iphone, Galaxy phone) to automotive (model year of cars) to even food items (Ben & Jerry icecream, Enfamil baby formula).

In your opinion, is this rate of innovation and its related marketing activities actually productive (for the manufacturer vs. for the customers) or is it a gimmick that sometimes benefit the manufacturer at the cost of cheating customers?
