The term used when a company's products are so closely related that sales of one brand take away sales from the other brand is brand cannibalization.
Step-by-step explanation:
The term used when a company's products are so closely related that sales of one brand take away sales from the other brand is brand cannibalization. Brand cannibalization occurs when the introduction of a new product from the same company competes with an existing product, resulting in a decrease in sales for the original brand.
For example, if a company sells two different smartphone brands and introduces a new model that offers similar features to the existing one at a lower price, customers may choose to buy the new model instead, leading to a decrease in sales for the original brand.
