Final answer:
Multiproduct branding is known as both corporate branding and family branding, which allows a company to market multiple related products under one brand name.
Step-by-step explanation:
Multiproduct branding is a marketing strategy that involves using one brand name for multiple related products. This approach is also known as corporate branding or family branding. With corporate branding, a company's overall reputation can extend over a range of products, which can reduce the costs of introducing new offerings because the brand is already recognized and established.
In contrast, private labels are products sold by a retailer under its own brand but manufactured by another company. A brand extension involves using an established product's brand for a new item in the same product category, which is different from multiproduct branding.
