What is the term for a group of related products sold by the same company?

The term for a group of related products sold by the same company is referred to as a product line. A product line consists of items that are closely related in terms of their functions, customer groups, or marketing strategies. Companies often group these products together to streamline marketing efforts, capitalize on brand identity, and make it easier for consumers to recognize and choose from a range of offerings that fulfill similar needs.

For instance, a cosmetics company may have a product line that includes various shades of lipstick, all targeting consumers looking for lip color options. By grouping these products into a single line, the company can market them collectively, making it easier for consumers to find what they need.

In contrast, the other terms do not accurately describe the same concept. A product category generally refers to a broader classification that can encompass multiple product lines from various companies. A product segment relates more to a specific market share division within a larger category. A product portfolio, on the other hand, is a comprehensive collection of all the product lines and individual products that a company offers, rather than just a focus on a related group.
